For the heating of a private house without centralized gas supply mainly use affordable and inexpensive solid fuel. However, traditional types of heating devices running on this type of fuel have a rather low efficiency and labor-intensives during operation. Not so long ago of long-burning boilers using a pyrolysis method, more efficient, economical in fuel spending and easy to maintain.

Criterias of choice

Pyrolysis boilers for home heating are designed to work on different types of fuel: wood, coal, peat, sawdust, pallets. The highest performance due to the full combustion of fuel in pyrolysis mode has wood-burning devices. Therefore, if there is a possibility of inexpensively and in sufficient quantities for the entire heating season to prepare firewood, then you can buy and install at home just such a boiler.

Otherwise, it is better to purchase a universal device capable of working on any solid fuel. Structurally, they are arranged so that they can burn in pyrolysis mode to 80% of fuel resources, and the remaining 20% \u200b\u200bin the mode of a simple solid fuel unit.

Also pay attention to:

the power of the unit. When calculating this indicator, the area of \u200b\u200bthe structure is taken into account, which will be heated by a pyrolysis boiler for long burning, and the level of protection of its rooms from heat loss;

the volume of combustion chamber. The boiler with a small size of the combustion chamber will require more frequent laying of fuel, so it cannot be left without servicing for a long time, especially in severe frosts;

the quality of the internal coating of the chambers. Cameras, in which the walls lined with cerama concrete are more protected from exercise, retain the integrity at the maximum level of heating and ensure proper fuel combustion;

duration of burning with full fuel loading should be at least 10 hours;

the level of automation for the safety of the device. Pyrolysis boiler for long burning should be not only productive, but also safe, so when you purchase it is necessary to check whether it is equipped with an alarm and automatic shutdown system;

the presence of an additional contour. The heating device with one circuit can only be used to heat the room. If the boiler is planned to be used to organize hot water, then you need to immediately buy a device with a two-door design;

cost. On buying a boiler should not save, since depleting models may not have enough technical capabilities for optimal heating of the room. It is better to purchase a boiler for proven brands, which have already passed the tests in the harsh Russian winter and deserved good reviews of the owners.

Comfortable life in the cold season is impossible without heating, except that you have not decided to winter in Thailand or on any other exotic islands. As for the furnaces and boilers, the length of long burning is a very good alternative to other types of heating devices. It all depends on preferences and goals.

Suppose that in addition to heat in the house you are interested in more and hot water supply, in this case it is worth paying attention to a double-circuit boiler on a solid fuel for long burning. Also, most likely, the pyrolysis boilers of long burning with water contour will come across the eyes - unlike the first, manufacturers say that they give up much higher efficiency of the efficiency, because the secondary gases will be survived, and not produced through the chimney. As for the price, solid fuel boilers of long burning of Russian production are cheaper than imported analogs.

To facilitate the search for numerous information, we made a small rating of solid-fuel boilers of long burning for premises of various purposes, so it remains only to choose.

What is better - a long-term combustion boiler on coals or firewood

This question is always asked for those who only think to switch non-solid fuel boilers of long burning. Consider the positive and negative aspects of each of the fuels.

In general, these are all the main criteria for which one or another type of fuel is chosen.

Video: What is the difference between a long burning boiler from the usual

Among the heating equipment operating on solid fuel, pyrolysis boiler occupies a special place. The miraculous properties of these heat generators are invented a lot of non-pieces. We want to dispel myths and objectively present solid fuel gasifying boilers in normal lights - as effective heat sources with their advantages and disadvantages. To begin with, explain what pyrolysis is.

Briefly about pyrolysis burning

The pyrolysis process is a slow decomposition of carbon fuel that occurs under the influence of high temperature with a lack of oxygen. The output obtains combustible gas or liquid fuel - depending on the initial raw materials and the conditions of flowing the chemical reaction.

Pyrolysis boilers of heating are produced and burning precisely gas, hence the second name - gas generator or gasifying. Primary raw materials - dry firewood, coal, fuel briquettes.

Scheme of gas generator installation, producing fuel for an internal combustion engine

Reference. For pyrolysis combustion, the most diverse solid fuel containing hydrocarbon connections is used. An example is the production of liquid fuel from old automotive tires or grinding of garbage in industrial gas generator furnaces.

How is the wood pyrolysis:

1. In a closed reservoir (reactor), a certain amount of crushed wood or sawdust is loaded.
2. The metal vessel is heated outside up to 500 ... 900 ° C, through the furma (blowing holes) air is limited to the air.
3. The tree is tweet and decomposes into the components - hydrogen, methane, carbon monoxide, water vapor, carbon dioxide. At the end of the reaction, a little ash remains at the bottom.
4. The resulting gas mixture is cooled, cleared, then pumps into cylinders for further use.

Before loading inside the gas generator, wood is dry. Otherwise, the heating energy will be spent on evaporation of water, the pyrolysis reaction will slow down, we get a bunch of water vapor.

It should be noted that any process of burning solid fuel is accompanied by the separation of wood gas, even in a fire (watch a photo). Read more in our other publication.

2 types of gas generator boilers

The principle of operation of both aggregates is the same, only burning is organized in different ways. In any pyrolysis boiler there are 2 cameras:

• a fuel, where burning, decomposition of firewood with separation of combustible gases;
• the secondary chamber, where the furnace gases burn out, highlighting additional heat.

That is, the principle of the pyrolysis boiler is based on a separate fuel burning. Wood burns, gives heat and heats up the upper layers, which is precipitated by carbon monoxide and hydrogen. The mixture enters the secondary chamber and burns due to a separate air supply.

For a more understandable description of wood and coal heat generators, we decided to take advantage of the classification of the famous Czech ATMOS company, which produces two-chamber heaters for more than 10 years. So, boilers are divided into 2 groups:

1. Ordinary pyrolysis. Here, the separation supply of air is organized due to the natural thrust of the chimney.
2. Gasifying models with compulsory upgrade using a fan (or smoke), equipped with automatic.

Consider each species separately, using the ATMOS boilers as examples.

The principle of operation of the pyrolysis unit

To describe, take a low-power model ATMOS DC15E with a maximum capacity of 15 kW. From the inside the pyrolysis boiler looks like this (oriented according to the drawing):

On the left in the photo Fuel bunker with nozzle, on the right - the secondary free chamber

Note. The maintenance of pyrolysis thermal generators of other European manufacturers (for example, Buderus, Viessmann) is almost no different from the design of "atmospheres", although the latter are noticeably cheaper.

DC15E solid fuel boiler operation scheme Next. Large lamps are laid in the furnace and roasting, the primary air goes through the damper in the back wall. Further processes:

With full operation, the temperature in the fuel will reach 800 degrees, the unit goes to the maximum efficiency of 83% (executed by the manufacturer). If you "press" the air damper and translate the boiler into long-burning mode, efficiency will fall to 71%.

The reason is to reduce the amount of heat from direct burning of firewood, a decrease in temperature, a slowdown of pyrolysis. The appearance and design of the heater is represented by video:

Description of gasifying heat generators

In general, the design of these boilers repeats the device of pyrolysis heat generators, but there are significant differences:

• primary and secondary air is injected with a fan, as a rule, with a smoke activity;
• air flows are directed to fuel from the side walls;
• the temperature of the coolant is controlled by the automation unit;
• changed the shape of a ceramic nozzle and a bump in the secondary compartment;
• in the back of the heat-tube heat exchanger;
• The efficiency of the boilers lies within 81 ... 87%, the greatest flame torch temperature is 1250 ° C (the data of the manufacturer "Atmos").

The design of the gasifying boiler in the context. The air for burning is supplied with a smoke of the holes from the holes in the side walls of the fuel (not shown in the diagram)

The principle of operation of the gasifying heater is the same - the upper compartment serves as a bunker for firewood and a gas generator, incineration occurs in the lower. Thanks to the high flow of air in the bar, the flame torch is formed, the temperature, wood and coal burns better.

Gas-generating boilers of different brands may differ in small-scale shape - a form of the fuel, methods of air distribution in chambers, a nozzle configuration. In low-cost models instead of figured ceramics, a brick lining can be used, there is no water cooling circuit, the metal is 4-5 mm thick.

Operating Rules

To get a good heat transfer from a gas generator heater with minimal fuel consumption, manufacturers recommend adhere to the following rules:

• use only dry firewood, permissible humidity 12 ... 20%;
• when installing and strapping the boiler, it is necessary to apply a three-way mixing valve or a complex LADDOMAT-21 device to support the temperature in the return line at 65 ° C;
• the operating temperature of the coolant on the supply - 80 ... 90 ° C;
• the heat generator should work on the power close to the maximum, it is impossible to operate the unit in low-performance mode for a long time (less than 50%);
• it is very desirable to cooke with large lamps, but not round decks;
• together with pyrolysis boilers, it is strongly recommended to use a buffer container that will accumulate excess thermal energy;
• the requirement for the minimal volume of the heat accumulator is 25 liters for each kilowatt of the power of the heater.

Explanation. If a cold coolant with a temperature is less than 65 degrees in the boiler, then condensate and dispatch is formed in the process of gasification of fuel in the primary chamber. Read more about the correct strapping in a separate manual about.

The supply of coolant into the boiler must be adjusted to the three-way valve. After the buffer tank, another mixing unit is placed to reduce water temperature.

The use of buffer containers is due to the effective mode of operation of the boiler - intensive burning, the temperature at the outlet of 80 ... 90 degrees. It is under such conditions that the high efficiency of 86-87% is achieved. "Strain" the heat generator in the air can not, the combustion efficiency will decrease to 40-50%, as the homemade bourgeitous stove.

Real advantages of pyrolysis heaters

We list the advantages of gasifying boilers, declared by sellers, and then we scan frank bikes:

• pyrolysis thermal sources are full-fledged gas generators excreted by combustible synthesis gas;
• the aggregates are very economical and environmentally friendly due to the high efficiency;
• boilers completely burns coal and firewood, almost without a balance;
• the duration of burning is over 10 hours (the most modest indicator is 8 hours).

The first statement is too bold. Recall: Intensive pyrolysis begins with strong heating and lack of oxygen, and what happens in the boiler? The fan is inserted into the air in the furnace with an excess, there is no damage. Synthesis gas, of course, stand out, but direct fuel burning is also present.

On the left is shown the flame torch in the survival compartment during the boiler operation, on the right - a fire-cutting heat exchanger (top view)

We will analyze the rest of the advantages:

1. Approval about economy and environmental friendliness is not a fairy tale. Due to the decent efficiency, the boiler is better mastering the fuel energy and throws up much less toxic compounds into the atmosphere - nitrogen oxide and carbon monoxide. For 1 condition: recommendations on the mode of operation and humidity of firewood are fully respected.
2. Causes of more complete combustion - dry firewood and forced air injection. If you put briquettes from sawdust or dry acacia into the traditional turbocharged boiler, then the ash residue will also be zero. A lot of light ash is simply blown out by a fan in chimney. This means that the fact is not the advantage.
3. The duration of burning depends on 2 factors: efficiency and fuel compartment capacity. By efficiency, solid fuel boilers lose pyrolysis by 10%, this is a small increase for the duration of work. The main factor is the volume of the combustion chamber, if it reaches 80 liters and more, the firewood is roasted for 6-8 hours.

Reference. The Czech manufacturer of ATMOS describes the advantages of its heat generators (literally): a large fuel hopper is a long burning time. Hence the conclusion: a statement about the duration of work truthfully, only the reason for the other is the cooler of the furnace, and not the fact of generation of wood gas.

Also, many non-pieces are described about the cost-effective mode, which is simply missing in pyrolysis units. In the operating instructions "ATMOS DC15E", it is written - a decrease in the intensity of the flame leads to a decrease in efficiency and increase fuel consumption.

Essential cons of boilers

If you visit any online store of heating units and ask how much pyrolysis heat generators cost, then you will immediately see their main disadvantage. Not the most expensive Russian boiler "Suvorov M" K-20 (20 kW) will cost 1320 y. e., and Identical power ATMOS DC 20 GS - 2950 y. e. For comparison: the price of the cheaper traditional heater Buderus Logano S131-22 H is 1010 y. e.

Denote other disadvantages of heat gas fiction:

• 2 cameras, lining of brick or ceramics plus a water shirt at the bottom of the case - the listed structural solutions significantly increase the mass and dimensions of the aggregates;
• high fuel quality requirements;
• the heat carrier with a temperature of 80 ° C is rarely used when heating private houses, it means that it is not necessary without expensive;
• ceramic details of the lining are not eternal - the nozzle can crack from overheating and will have to be changed.

I must say pyrolysis boilers attract homemade craftsmen. But it is very difficult to make such an aggregate with their own hands, experience and investment in the purchase of materials need. Free to make the heater will not work. It is much easier to cook the usual or mining boiler.

Note. Judging by the reviews of the owners of boilers on thematic forums, the use of raw firewood is still possible. The algorithm is such: the unit melts and warms with dry lamps, then wet wood is thrown out. But the share of such fuel should not exceed 30%, otherwise soot and soot will go. Let's listen to the opinion of the expert on the video:

Choose from all existing boilers pyrolysis makes sense with such a situation:

• you are willing to pay for the efficiency and preservation of the environment;
• the budget allows you to purchase a heater and heat accumulator of the desired volume;
• the boiler room has enough space for equipment;
• there is an opportunity to harvest high-quality firewood, buy briquettes or dry freshwater wood.

The heat generator model is selected by power and functionality. How to fit on firewood for home, read in our instructions.

Initially, pyrolysis household boilers are designed to install the battery tank and using good fuel. This is a Western European practice, where solid fuel units cannot be operated without a buffer tank.

Our income is not so high, therefore, homeowners are saved on all - equipment, combustion, combustion method. Hence the conclusion: at the moment, gas-generated installations are incompatible with the needs and expenses of most homeowners, because they will not be able to properly exploit.

Fuel

Pyrolysis boilers are effective on fuel with high yield of volatile substances - wood (firewood, wood waste, fuel briquettes and pellets), corner brown; Some models consume stone coal (class "Walnut 1" or "Stone") and even coke. This type of boilers presents sufficiently high requirements for fuel humidity - for firewood no more than 20-35%. This is due to the fact that water vapor dilutes pyrolysis gases and prevents the burning (see below), when working on a wet fuel, the power drops sharply or the boiler will swell at all. In situations where there is no dry fuel, it is a serious disadvantage.

It is interesting: wall gas boilers heating

Plot thickness

This value is in reverse proportionality to the inner diameter of D. It is necessary to achieve an optimal piston pressure on the fuel bookmark. If the pressure is insufficient, it will reduce the reverse action coefficient. As a result, the opposite firebox fire may occur with further exit of smoke through the pipe. If the piston is very heavy, it will noticeably reduce the air layer necessary for high-quality combustion: as a result, the flame will fall.

The ratios between the inner diameter and the thickness of the pancakes are approximately such:

• 30 cm - 6-10 mm.
• 40 cm - 6-8 mm.
• 60 cm - 4-6 mm.
• 80 cm - 2.5-4 mm.

Device and principle of boiler

Earlier it was already said that boilers of this type have cameras. The furnace is divided into a gasifying chamber, which is loaded with fuel and directly - the combustion chamber.

In the figure, the diagram shows the internal device of a solid fuel boiler pyrolysis type

In the first chamber, where the air flow is limited, fuel is loaded. The boiler starts and works as usual. With slow burning, the fuel starts to pyrolized, the wood gas is distinguished, which is already in the second part of the furnace, in the combustion chamber. From this point on, a solid fuel boiler goes into the operating mode. Now the processes are beginning, which are fundamentally distinguished by pyrolysis type of burning, solid fuel heating boilers of long-burning burning from the process of direct burning and from traditional boilers.

In the first chamber, heat loss is minimized. Usually in models of solid fuel boilers of long-burning, the space between the first and second chamber is filled with grate, which is stacked by fuel.

The second part of the furnace is the combustion chamber, where the combustible wood gas comes. The camera is filled with secondary, heated air. The principle of double blast already operates here.

After the outlet of the boiler to normal, working mode, air access to the first chamber is significantly limited. The combustion process is practically stopped by moving to the condition. Fuel burns gradually. Each previous layer of fuel in the process of tension gradually uses the subsequent layer. Slowing is accompanied by a constant separation of wood gas. Due to this process, solid fuel pyrolysis boilers are still customary to be called long burning boilers.

In the second, the main combustion chamber is only a wood gas, which, when in contact with the secondary air (heated to T 3000 C), gives a huge amount of thermal energy. Only now the heat energy comes into operation, heating the heat carrier, circulating in the heat exchanger. Those, in the design of solid fuel boilers of pyrolysis type, the heating of the coolant is carried out not due to the direct combustion of solid fuel, and already due to the combustion of the secondary product of the combustion - pyrolysis gas, a fuel gaseous substance. This is the main difference between boilers of this type from solid fuel boilers of other species.

What is meant by pyrolysis

Pyrolysis is a combustible gas generation and its subsequent burning, - occurs in all solid fuel boilers, to a greater or to a lesser extent. The same process is also in a conventional furnace - when burning firewood or coal, in some place there is not enough oxygen, the carbon black gas appears, then it fits missing oxygen and burns, highlighting heat, turning from the poison to conventional carbon dioxide - CO2 .

As experiments, the 1950s scheme developed a scheme of boiler equipment, where first the fuel was pulled with a lack of oxygen, then the obtained from was waited in the secondary chamber. But ideas were not embodied, as not any advantages with weighty disadvantages and expensive.

How to make pyrolysis boilers do it yourself

The technological process of manufacturing the boiler of the pyrolysis principle of operation involves performing plumbing and welding work.

Necessary materials and tools

For the manufacture of a high-quality unit, experience is needed in working with the following tools:

• electrical welding machine;
• electric drill;
• angle Grinder;
• a set of plumbing tools - a square, level.

Materials and components will be required:

• sheet, thickness 4 mm, 7.5 m²;
• tube - 8 m (diameter 57 mm, wall thickness 3.5 mm);

strip steel (thickness 4 mm, width 20 mm) - 7.5 Mp;
strip steel (thickness 4 mm, width 30 mm) - 1.5 Mp;
strip steel (thickness 5 mm, width 80 mm) - 1 MP;
Chamotted (refractory) brick - 15 pcs;
Profiter 70 × 30 (wall thickness 2 mm) - 1.5 Mp;
Profiter 80 × 40 (wall thickness 2 mm) - 1 MP;
Circle cut D 230 - 10 pcs.;
Circle grinding D 125 - 5 pcs.;
electrodes - 5 packs;
temperature sensor.

They are automatically performed by dampers: opening (to increase the combustion temperature) and closure (when the maximum temperature is reached)

The temperature sensor is a mechanical device for monitoring the amount of air passing into the combustion chamber.

The productivity of the boiler depends on the functioning of the chimney pipe. To ensure good thrust, the chimney must comply with the quality requirements:

• height is not less than 5 meters;
• good insulation;
• no sharp bends;
• condensate removal;
• easy cleaning access.

Drawings and device schemes

Pyrolysis boiler without forced ventilation has the most simple scheme. The energy and volatility of the design shall heare the operation of the aggregate.

The diagram of the pyrolysis boiler with a natural chimney has the form:

To increase the high efficiency, some designs have double base walls.

The boiler consists of three main cameras:

• loading, serving for fuel cast;
• locking chamber, where the secondary air is served;
• heat exchanger overlooking the pipe.

The combustion of raw materials directs the gas flow from top to bottom. When air is supplied under grinding in an array of chammed brick, the combustible gases survive occurs. Debris products go through the heat exchanger in the chimney. The thrust adjustment is performed by a thermal sensor at the outlet of the boiler using a chain associated with the feeder of the secondary air supply.

Detailed detail with dimensions and tolerances can be taken in a standard drawing:

A - boiler contour controller; B - load door; C is the ashbar cover; D - chimney; E - coupling for the temperature fuse sensor; F - safety valve nozzle; G - feed line of contour; H is a cooling water supply to the heat exchanger; L - return highway contour of the boiler; M - expansion tank

Step-by-step manual of the aggregate

The manufacture of pyrolysis boiler with their own hands is divided into steps:

1. According to the drawing, markup and cutting parts for the housing are performed. After the "sticking" of the elements, the control measurement is performed, then welding seams are made. The rear panel and side walls installed on their places are welded on both sides, are cleaned, processed by welding sealant.
2. Installation of heat exchanger pipes.
3. After boiling the outer wall and the door shells, a mechanical controller of the coolant control is installed.
4. The chimney is assembled by increasing the pipe. The subsequent part should be inserted inside the previous one so that the condensate does not fall on the outer side. The finished design is painted refractory paint.

Pyrolysis boiler work principle

The chemical process of decomposition of wood under high temperature effects (from 200 to 800 ° C) with limited oxygen access is called pyrolysis

The action of the pyrolysis boiler is based on the principle of dry distillation. Heating firewood with a lack of oxygen leads to the formation of wood coke and gas. The resulting gas when mixed with oxygen focuses. At the same time there is interaction with carbon. Combustion products emerging from the boiler contain a reduced amount of harmful substances. A firm part of the wood, burning, highlights thermal energy.

Pyrolysis effect can be obtained from fuel combustion of various types:

• firewood (bars the size of no more than 450 × 250 mm);
• grinding branches;
• briquettes;
• sawdust;
• pellets (wood granules);
• peat;
• coke;
• coal.

Wood is the most effective type of fuel, outstanding a large amount of pyrolysis gas. It is possible to mix branches and sawdust in a size not exceeding 25% of the total volume to save the efficiency (efficiency ratio) at a high level.

The distinction of the maintenance of pyrolysis boilers from traditional is the presence of two fuel chambers: fuel (gasification) and combustion.

As a result, the formation of charcoal and gas, accompanied by the release of a large amount of thermal energy

The design of pyrolysis boilers are distinguished depending on the air supply method: natural, using chimney thrust, and forced, injection air fan.

In the installations with a natural burden, the secondary chamber is located above the main furnace and the air flow passes upwards. With artificial traction, on the contrary: the main furnace - under the secondary chamber and the direction of the air - from top to bottom.

What is it necessary for what

Pyrolysis boilers are becoming increasingly popular due to the growth of the cost of other energy carriers. The heating of premises is becoming more expensive. Firewood is the cheapest type of fuel for traditional boilers, but they need a lot.

The use of additional energy from the combustion of the gas highlighted during the pyrolysis of wood allows to obtain significantly more thermal energy.

Compared to boilers working on other types of fuel, the mains of the pyrolysis principle of operation have the following advantages:

• reducing air flow rate on the process of gas combustion;
• fewer waste - soot and ash;
• reducing 3 times the release of harmful substances and components;
• an increase in the boiler operation (time interval between fuel loading (up to 12 hours);
• the ability to adjust the capacity of the boiler in the range of 30-100%;
• facilitating the process of controlling the combustion of pyrolysis gas.

Features of the stove of long burning

First of all, you need to understand what is happening during the burning of firewood. For the appearance of flame, the temperature of the wood must be brought to about +150 degrees using an external heating source for this. Usually enough of the piece of paper burned from the usual match. After that, the process of slow coagulation of the material begins, which, after reaching the mark of + 250 degrees, goes into disintegration of simple chemical elements. The composition of the smoke of white, which appears during the ignition of the flame, includes gas and water vapor: they exude a heated wood. The ignition of the released gaseous components is observed when heating in +300 degrees is reached: as a result, the thermochemical reaction is significantly reduced.

The decay of the organic matter on simple elements is called pyrolysis. Practice shows that during the combustion of wood, part of the energy potential laid in it remains not used. This is expressed in a significant amount of waste remaining after the fading of the flame. In pyrolysis furnaces, fuel is used much more efficiently, which is achieved by individual burning of gases released during burning. At the same time, the velocity of the wood itself is very small, which contributes to an increase in the work of the furnace on the same bookmark. The bunch of bunch, which is a type of pyrolysis heater, guarantees almost complete combustion of all fuel.

Pyrolysis boilers long burning with water contour

Pyrolysis boilers of long combustion with water contour are an excellent alternative source of energy in private houses under frequent gas supply interruptions.

Copper solid fuel long combustion with water circuit can work on firewood and on other types of solid fuel: coal, wood waste, etc.

The main minus of this type of boilers is a high price. In addition, in contrast to many other types of boiler equipment, the pyrolysis boiler of long-term combustion with water contour is most often energy-dependent.

Not only the circulation pump and the control devices are powered by electricity, but also a built-in fan: on natural thrust this equipment, as a rule, does not work.

Solid fuel wood and coal boilers are inferior only to gas. At the same time, they have one serious disadvantage - loading the fuel must be carried out several times a day.

With the usual combustion of firewood, the efficiency of boilers does not exceed 75%, and some of the combustible substances simply flies into the pipe.

Pyrolysis boilers of long-burning combustion with water circuit are much more practical and more efficient.

No one will be a secret that boilers Pyrolysis heating are currently very necessary and demanded by the devices of heating systems. It was for this reason that very many of our people began to be interested in these aggregates.

Pyrolysis boiler is a special heating boiler, which can use pallets, coal, wood, and other materials as fuel.

One of the main criteria, depending on which heating boilers are subdivided, is the type of fuel on which they work. Thus, in today's market you can find boilers on pallets, coal, firewood. You can also find the so-called universal boilers for yourself.

The most common currently wood solid fuel boilers that have many advantages. The first is that fuel is considered the most affordable. It should also be noted that such boilers are sold at reasonable prices.

A distinctive feature of pyrolysis boilers is to control the level of oxygen in the combustion chamber, and, accordingly, temperature control and fuel combustion rate. Pyrolysis boiler on solid fuel will ensure your independence from gas and electricity, since the cost of these energy sources significantly exceeds the cost of solid fuel.

Construction foundation

The base under the bunch of bunch is laid in this way:

1. The first thing the square pit is digging. Its approximate dimensions - 150x150 cm, with a depth of 20-30 cm.
2. The bottom of the trench is covered with a cushion from rubble and poured with a solution of concrete. For aligning its surface, a trowel is useful. When the flooded site is grabbing, it is necessary to check the horizontal surface of its surface with the help level. If necessary, additional adjustment is performed.
3. On top of a completely dried concrete stand, a refractory brick is placed in several rows. Usually there are enough 2-3 layers.

Strong and weaknesses of bubfoni

Pyrolysis stove has a number of positive qualities:

• Easy design. Having welding skills and work experience with metal, the stove will not make a lot of work.
• Universalism. Bunch is very unpretentious in terms of fuel: it can throw firewood, coal, sawdust, chips and other types of wood waste. Also, the stove copes well with pellets - inexpensive eco-friendly granules.
• Duration of work. The breakdown time of one wood laying is almost a day: throughout this time, the oven regularly allocates heat. This indicator may vary depending on the modification of the device, the volume of its furnace, the rate of circulation of oxygen, etc.

It should also be mentioned about the main disabilities of Bubafoni:

• Low efficiency. The reason for this is the uneven heating of the body of the device at a sufficiently low heat transfer. More "advanced" pyrolysis furnaces in this regard an order of magnitude more efficiently: their efficiency often exceeds 90%.
• Uncomfortable cleaning. As such, the ashist in the design is not available, so the remnants of combustion products are removed through the top. Some furnace modifications are equipped at the bottom of the door that facilitates the procedure for cleaning ash and ash.
• Low aesthetics. The appearance of the bubfoni can hardly be called beautiful, so it is mainly used for the heating of utility rooms.

Drawing up drawing

The main proportion along the manufacture of the homemade stove of the bunch of gas cylinder is the mathematical ratio of the parameter of the internal diameter of the case and its height. It must be from three to five to one. The optimal diameter value is from 30 to 80 cm.

Making the diameter of the furnace case less than 30 cm is not effective, since oxygen too quickly will circulate along the combustion chamber, without entering into a full-fledged reaction with firewood. This leads to a noticeable decrease in the efficiency of the device. In the chambers with a diameter of more than 80 cm, another problem occurs - in it firewood from the edge is very slow, and in the center - faster. In the course of fuel burnout, a failure arises, in which the piston is lowered. As a result, the flame gradually fades. In the drawing, the diameter is more convenient to designate the letter D, and height - H.

Types of fuel

Osinovye Eurodova

One of the most positive properties of pyrolysis boilers is that they are capable of efficiently operated on any solid fuel.

It may be black and brown coal, as well as wood and peat, etc.

Of course, on each of these types of fuel, the pyrolysis boiler is capable of working for a certain time until it is completely burns.

The combustion time of different fuel as follows:

• brown coal - 8 hours;
• solid wood - 6 hours;
• soft wood - 5 hours;
• black coal - 10 hours.

As observations show, the most effective fuel for pyrolysis boiler is dry wood. It, with a length of 45-65 centimeters, allows the boiler to function most effectively and increase its operation time.

But if these fuels are missing, you can use any kind of organic fuel.

Fuel briquettes

Of course, if it is allowed for use in such a boiler.

The permitted fuels include:

• briquettes and pellets for heating;
• wood waste;
• industrial waste containing cellulose;
• some varieties of peat.

When heating, it is necessary to take into account that if the consumption of primary and secondary air is chosen correctly, and the air humidity is not higher than that, there will not be highlighted by combustion.

Be careful: if the moisture is high, then the release of a strong water vapor is inevitable, which means that it will be inevitable, it will appear to appear, soot, the calorific value characteristics of the gas will deteriorate and the boiler attenuation can occur.

Scheme, work features

Secondly in the 2000s, when the average manufacturer had sufficient production capabilities and materials, production began on the household level. The consumer falsely caused interest - sales and profits appeared.

The diagram of the pyrolysis boiler is usual - in a large chamber, the firewood tab is first flared up, then the automation overlaps the air and with its lack of firewood for a long time. The release gas and a large amount of solo particles - pure carbon with mixed with heated air in the secondary chamber, where they are expensive.

In this burner, there is always a reddish flame - a direct sign of the reaction with carbon participation.

How to increase the PDD pyrolysis furnace

Basically, the KPD of Bubafoni is reduced due to uneven heating of its housing; This leads to a deterioration in the effectiveness of the heat transfer of the device with the surrounding space. There is a fairly simple way to optimize the process using a corrugated metal sheet. An improvised shirt for the case is made of it: it is fixed on top of the cylinder with welding or twigs.

Another popular option for increasing the effectiveness of the pyrolysis furnace is a boiler bunch with a water jacket. Most often, the water circuit is made of a metal barrel or drawer, pouring water in them. By placing the gross bubonchi inside the manufactured design, it is possible to achieve water heating and put it inside the heating system. Thus, it is possible to acquire a kind of boiler for heating an extensive room.

Creating a water shirt, you need to take all the necessary measures to make it the most reliable. If the box is used for these purposes, it must be qualitatively suited, in order to avoid leaks. All seams are desirable to tap the heat-resistant sealant. The recommended thickness of the steel sheet for the manufacture of a water circuit is not less than 3 mm. From above, the box is best to close the lid with the handles. The oven of a long-burning bunch with a water jacket may additionally be equipped with a heat exchanger consisting of thin tubes.

There are several useful tips for better and safe operation of the furnace from a gas cylinder long burning:

• Installation of the device in the room is best carried on a sheet of metal.
• The space around the furnace must be released from any flammable items.
• When fuel ignition, it is not recommended to abuse fuel liquid.
• The body of the product is quite strong, so when servicing the heater, it is necessary to carry out in thick gloves.
• To extinguish the flame, the flap closes on the air pipe.
• Painting the bubfonet parts is strictly prohibited.

The homemade pyrolysis oven from the gas cylinder is one of the most popular options for manufacturing. He bribes his cheap and simplicity. All materials will be easily found at any dacha.

She will not hit the big house, but for a small cottage, garage, greenhouses are the most.

Such a furnace easily cope with the heating of the room in 100 m 2. It is often used for heating greenhouses, garages, warehouses. Does not require a foundation device, but the basis still needs to be prepared. At least, align and close with a metal sheet, a thickness of at least 4 mm.

It is also important when installing comply with all fire safety rules. The distance to the combustible objects should not be closer 50 cm

Wooden surfaces are additionally protected by non-splashing web.

Operation of the furnace

Before the bunch of bubfoni from the inside of the case, it is necessary to remove the welded air duct, removing the upper cap before that. The inside of the stove is a laying of wood manneys in a horizontal position, frightened to each other. With a vertical tab, some obstacles can occur on the movement of the piston: it usually happens in cases where the lamps are not completely roasting. As a result, the depression in the primary chamber will turn into a full combustion, which seriously disrupts the proper functioning of the furnace. Firewood in this case is consumed much faster, and from the duct begins to leak smoke. When laying a manpiece, it is forbidden to overlap the plot where the chimney is welded.

A layer of chips, sawdust or crushed branches pour on firewood. From above, you need to put an old fabric or paper impregnated with kerosene. On the fuel tab, the fuel is installed piston and the lid is put on. For the ignition of firewood, you need to set fire to a piece of vehicle or paper, and throw it inside through the air pipe. Matches in this case are ineffective, as they go out, not having time to reach fuel. After sunbathing, wood pause is 15-20 minutes, giving them well to flared. When the flame takes strength, the airpipe valve should be closed: thus the bunch is translated into the main operating mode.

A bit of history

The development of the bunching furnace is attributed to the folk crawler Athanasia Bibyakin from Kolyma. Subsequently, a new invention was named in his honor. Athanasius during their experiments was repelled from the device of the pyrolysis boiler Stropuva Lithuanian production.

The domestic inventor tried to simplify the design as much as possible so that it could be constructed with their own hands. This specificity of Bubafoni and explains its high popularity. Considering the fact that the material for the manufacture of this device is mainly protruding tools, it cannot boast by external aesthetics. The strong sides of the stove is its simplicity, efficiency and reliability.

Pyrolysis boiler from gas balloon instruction

This design in the people is called a bunch. Such a nickname was the inventor-cradle from Kolyma, who first posted an idea on the network.

The movable piston divides the combustion chamber into two segments: the firewood is burning at the bottom and the pyrolysis gas is burning from above.

In such a boiler, the firewood burns almost no residue

Air movement is directed from top to bottom. The burning is much slower than in the traditional boiler.

Oxygen enters through a pipe that serves as a piston rod. For the combustion of pyrolysis gas oxygen enters the holes where the piston pipe is inserted into the lid. The connection should not be sealed. The separation of cameras ensures the extension of the entire volume of fuel.

Adjusting the combustion intensity is carried out through the pipe connected to the piston ring. For convenience, a pin with a movable metal disk is welded to the pipe, the size of which slightly exceeds the pipe diameter. Adjusting the gap between the pipe and the disk are achieved by the desired temperature.

The following materials are needed for the manufacture of bubfoni:

• cylinder with a volume of at least 50 l;
• armature;
• metal strip (steel).

The device consists of parts:

Assembly and welding

Installation and welding work follows:

1. Cut the rounded part of the cylinder by receiving the housing and cover. Collect slice places with a grinder. On the side cut the loading hole for fuel supply.
2. From the reinforcement to make a grid, through which burnt firewood will wake up.
3. Make a piston: to the iron disk to weld the blades on the one hand, the pipe is on the other.
4. Perform the installation of chimney. For better thrust, you can use a gradual increase in the pipe diameter in the direction from the beginning to the end.

Cove the design of refractory paint.

The combustion process leads the blade in motion. Aerial vortex streams are created, but the disc is preventing the increase in flame. The result becomes the pyrolysis effect from the decline of firewood for 8-10 hours. Loading fuel is made 1 time per day.

Such a boiler can drop the room large size. It works on different types of solid fuel:

Getting more thermal energy from wood makes the use of pyrolysis boilers are increasingly attractive. Having skills in fitter and welding works, you can make a heating unit of the pyrolysis principle of action with your own hands according to drawings and diagrams or from the old gas cylinder.

How to make a pyrolysis boiler with their own hands from a gas cylinder step-by-step instruction

To begin with, the drawings of pyrolysis homemade boilers are required. They are found in the appropriate literature or on the sites of homemade craftsmen

It is important to consider aggregates with detailed video and reviews from real owners, during operation of improving their own invention. From materials and tools will be required:

1. Steel sheets and profile pipes with a thickness of 3 mm. If less, then over time, the combustion temperature of firewood deforms the unit and leads it to disrepair at the time of work, which is fraught with the risk of roasting the walls and the emergence of a fire-hazardous situation.
2. DC welding machine and corresponding electrodes.
3. Drill with diamond drills and grinding machine with similar discs.
4. Accessories Boiler: Doors, ash bar, blowing fan.

Depending on the design and drawings, the models of the aggregates are different. If a pyrolysis furnace is created with her own hands - the heating device is better holding heat, unlike iron, then chamotte brick and asbestos or palylated sheets is added to the set.

The algorithm or step-by-step instruction consists of the following items:

• According to the planned sizes, the cooked sheets of steel and profile pipes are cut. The edges of the workpieces carefully pass through the diamond grinding circle - welding will be easier and the risk of breaking will decrease.
• The housing is welded - the end of the end is stacked on the horizontal surface, and the walls and the lid are fixed to it.
• Inside the boiler have a furnace with a grate grid. In the middle there is a nozzle for the removal of exhaust olefins - gases with high temperatures.
• The cooling system is assembly. It consists of several profile pipes overlooking the boiler.

View video

It remains to be accepted on the heating boilers with your own hands the front wall, equipped with a pensive and loading door, set the unit to the appropriate bed and test.

Install the boiler with your own hands on the concrete plane, flooded in terms of the level and covered asbestos sheets. If there is no possibilities for the fill - the weight of concrete affects the foundation, the floors are disassembled, lay out the bricks, rip off the parenchite and are covered with sheet gland. So, the safety of the improvised boiler house will be observed. Pyrolysis boilers do it yourself - it's easy, just need to try a little.

Design

The bunch of long burning bunch includes the following nodes:

1. Case. The main element of the device usually having a cylinder form. It is most often made of cylinders, barrels, large fire extinguishers, thick boiled pipes, etc.
2. Chimney, according to which combustion products are distinguished. The material for its manufacture usually performs a metallic pipe with a diameter of 110-250 mm. It is fixed by welding on the top of the furnace.
3. Piston. Ribs are welded on the lower part of the metal circle: the air duct pipe is fixed in its central part. At the expense of the ribs, the creation of an additional interlayer of air separating fuel and piston is achieved. This makes the process of tension more efficient and stimulates the active release of pyrolysis gases.
4. Regulator. Thanks to this valve, oxygen is supplied inside the furnace.
5. Cap. It has holes for the air duct, forming a secondary combustion chamber in combination with a piston. Inside this compartment, pyrolysis gases are combustion.

How is the construction assembly with a water jacket

Production of chimney is carried out in the following alternateness of operations:

1. Gently cut the balloon at the top. From the resulting case, the cap is subsequently produced cover for the boiler.
2. The bottom of the balloon is equipped with homemade legs. Each of them before fixing must be set exactly in terms of level.

The piston is constructed in three stages:

1. A steel circle is cut: in cross section, it should yield to the internal diameter of the cylinder approximately 35-45 mm. Thanks to side gaps, pyrolysis gases without interference will be seeded into the secondary chamber. In the center of the circle, a hole is performed under the air duct: this pipe should be inserted into it quite tight.
2. Next, welding is carried out with each other of the metal circle and pipes.
3. A piece of the chapellera is welded over the piston base.

For the manufacture of the furnace cover, you can use the upper cut part of the cylinder. On its surface, markup is applied to the air duct tube with a fixed feed piston. At the same time, it is necessary to provide a certain stock for the free movement of the pipe. Available on the applied lines. The homemade cover is drawn up with handles, for which fittings bent in vice. Now you can start setting the chimney at the top of the improvised pyrolysis furnace. With the help of a grinder, a cutout is made under the pipe blank: welding is also used to fasten the parts.

At this, the main part of the work on the construction of bubfoni is considered to be finished: it can be commissioned. Install the furnace is preferably on a pre-equipped foundation.

conclusions

Having considered how to make different types of pyrolysis stoves, you can summarize that it is realistic to do only the design of the gas cylinder. Brick oven will not work independently, too complicated. A hostility from cans also has the right to exist, but you can only make it at home, it will not be done in the field. Finally, the oven on working out is simple, but dangerous, requires very attentive and neat operation. The risk is great enough, so we do not take it for heating the garage.

At the occurrence of winter colds, worries are worried at the owners of private households, which are fully responsible for heating their home. In those rooms where the capacity of the main heating is weak or is absent at all (sheds, garages), you have to look for inexpensive alternative ways.

How economical pyrolysis boiler

We calculate for the usual power of the middle house, savings with pyrolysis boiler. For example, burn in the usual device for the season for 7 months of firewood by 20 thousand rubles. At the same time, at the pyrolysis save about 1,800 rubles, - consumption of firewood by 18,200 thousand rubles.

But the fan with a capacity of 80 W., After working for 7 months at a price for 1kW of electricity about 5 rubles, it bails more than 1500 rubles. Total - savings no more than 200 rubles per year. Those. Treated 50 thousand rubles will never pay off.

Even if somehow savings are 1000 rubles (wonder-efficiency more than 92%), it is still 50 years old - not a serious period for payback. The largest maximum is the additional cost of boiler equipment should pay off over 10 years. Otherwise it is not profitable. There are no such indicators and close. What attracts the pyrolysis consumer boiler at a price, is a big load!

Pyrolysis - What is it?

Under the pyrolysis in the context of heating equipment understand the release of volatile gases in the process of combustion of fuel. The greatest intensity occurs at temperatures above 450 degrees and disadvantage of oxygen. This is taken into account in the design of pyrolysis boilers, which have two combustion chambers and adjustable oxygen flow.

In one chamber is on the fuel directly, and in the second gases secured. This allows much to increase the efficiency of equipment compared to classical solid fuel boilers. Pyrolysis type devices must be laid out the fuel only 2-3 times a day. To find the best long-burning pyrolysis boiler Consider possible configurations.

Features of the design and types of boilers

Number of contours

By the number of contours, pyrolysis boilers are single-mounted, dual-circuit and multi-mounted. One-contacts are intended only to ensure the heating of the room. In order to provide HBS with their help, you need to additionally buy an indirect heating boiler.

Dual-circuit models simultaneously drive the room and warm water for domestic use. They differ in more complex design, installation and high price. Such equipment is suitable for the house in which they constantly live. Sometimes multi-mounted boilers are found in which more than two contours. An additional circuit can be used, for example, to provide a warm floor.

Corps material

The pyrolysis boiler body can be steel or cast-iron. Steel boilers are easier and cheaper. They are easier transported and installed. More expensive cast iron models are distinguished by increased reliability. Cast iron resistant to corrosion and does not have welding seams. A minus is the fragility of the material, with a sharp drop of temperatures, it can crack.

Steel pyrolysis boiler

Upper burning

A separate type is the pyrolysis boilers of the upper combustion with the cyclic fuel laying. Such models can work on one portion to days. This is achieved due to the fact that a larger amount of firewood is laid, and only the top layer is always over. It should use only high-quality, well-dried solid fuel. A feature of use is that until the past bookmark does not procee, we cannot add firewood.

Principle of operation

According to the principle of operation, convection and air-haired models are distinguished. Convection boilers warm the coolant, which is subsequently distributed by pumps on radiators, which can be in different premises.

Air heating devices are designed to heat the indoor air directly. More often used in industrial industrial premises and in small houses with 1-2 rooms.

Dependence on electricity

Non-volatile models are equipped with a mechanical control panel. Easy to maintain and reliable. Electronic control boilers need electricity to work. Their advantage is more accurate tuning. A number of models are sold without control panel. It is separately purchased depending on the needs.

Pellet boiler panel atmosphere

Types of fuel

Firewood

One of the most effective types of fuel for pyrolysis boilers is a firewood. They have a very high percentage of the exit of volatile substances, which is required for the pyrolysis process. It is important to pick up dried wood, this parameter strongly affects the efficiency.

The wood boiler produces the smallest amount of harmful emissions into the atmosphere. Also on firewood, the duration of the operation of the equipment is large, due to the lack of sulfur in them, which destructively acts on the body of the apparatus. When purchasing it is important to choose the appropriate size of the bars. For this tape measure, the depth of the furnace is measured.
