Heat exchanger hot mix

The range of thermomechanical load plate from 0.5 to 1.5 m and the "long" heat circuit will cover a large amount of load, up to 70 m 3 / h in the case of a single-phase solution - this means that all connections will be in the head. It will guarantee the easy implementation of service and works with pipes and, in the case of dismantling the heat exchanger, there will be no need to disassemble pipes. Heat transmission becomes possible when the warm medium transfers energy through thin, high performance plates between the channels and delivers it to a cold antagonic environment without mixing them. The countertock creates optimal efficiency. Plates, as well as the input design makes it easy and efficiently carry out unconqual cleaning (sink) of all surfaces of the flow.

The corrugated spine surface provides a turbulent flow of a total effective area. In addition, this surface allows the "metallic" contact between the plates, and together, with the locking device on the seal, the package of plates is easily mounted. The package of plates is safely located between the movable and fixed frame supports.

Table of pipes

For comfortable accommodation In the house or in the apartment, it is important for both cold and warm water. To heat the water, the instruments of different types that use different sources of energy are in demand for their work. As natural gas It is one of the available energy resources, boilers running on such fuel are quite common.

Features

• In a direct heating boiler, an increase in the water temperature inside the tank occurs due to the immediate effect of heat released from gas combustion.
• Performance gas boiler High enough.
• Such devices are more economical electric direct heating boilers.
• Installing such a boiler presents some difficulties. First, it must be coordinated with controlling organizations. Secondly, for mounting the gas boiler requires a chimney.
• According to the installation method, gas boilers are nasty (such models contain up to 150 liters of water) and outdoor (more voluminous devices).

It is a gas boiler much more than electrical models.

Device and principle of operation

The main element of the gas boiler is a gas burner located in the combustion chamber under water tank. From her through a boiler tank passes a pipe, which disks combustion products. Heat is transferred to water in the tank and from the burner itself, and from this pipe.

The power of the burner directly affects the productivity and power of the boiler.In the wall aggregates, gas installations are usually used with a capacity of up to 5 kW, and in the outdoor - over 6 kW.

The outer corps and the tank of most modern gas boilers are made of metal. It can be both stainless steel and a different metal with an enameled coating. From the inside the wall of the drive is often treated with a coating that impede corrosion - glass-ceramic, titanium or other.

There is a thermal insulating layer between the water tank and the outer corps in gas boilers. Its function is to preserve the water temperature, which was heated in the boiler, for some time after heating. From above on the housing there is a control unit.

Water is supplied inside the gas boiler tank over the inlet nozzle, and is selected from the top of the apparatus along the outgoing pipe associated with the cerave of hot water.

Have a cottage or outside the city - the desired dream of many residents of modern megacities. Fresh air, calm, moderate physical labor On the plot, the lack of urban crazy fuss - what else is needed for a full rest! Therefore, the happy owners of cottages try to spend there as much time as possible, often and completely moving around the city for the entire summer season. And at another time in nature very well, and traveling to the cottage on weekends or holidays is practiced throughout the year, and often country possessions are at all become the main "resident" of the hosts.

But fresh air and calm, the peaceful situation is not the only components of the present homemade utya. In the premises should be maintained comfortable for living temperature, and it often becomes a problem. This is especially true when visiting cottages in the spring, autumn or in winter, but the summer of 2017 shows that no one is insured from the cold and in such a seemingly favorable period. There is a real brick oven in the country not all, and for a long time to mess around with her to warm the premises during the short-term departure. Electrical heaters - Pretty "voracious" in terms of expensive energy. But there is so much good decisionwhich provides modern heating devices - these are gas heaters for giving.

Let's get to know them closer - how they are classified which principles of work in them are laid on how to approach the choice of the optimal model.

Gas heaters and principles of their work

Exemplary classification of gas heaters, their common advantages and disadvantages

It would seem - the device in such heaters is general, and is based on principle - the burning flame warms the air, which, in turn, provides normal temperature in room. However, this is not at all. Device of many modern devices Based on the use of modern technologies for developing and transmitting heat. So the design and the principle of operation different types Gas heaters can differ dramatically.

All gas heaters can be classified into several groups:

• Heat gas guns (powerful fan heaters).
• Ceramic gas heaters.
• Gas convectors stationary installation.
• Gas catalytic heaters.
• Compact portable gas heaters.
• Street infrared heaters.

Despite the differences in the design and principles of action, all the instruments of this type are characterized by approximately the same advantages and disadvantages.

Understandings include the following:

• Natural gas, network or liquefied, is the most affordable value of the cost of all other types of energy carriers. That is, such heating will not require significant operating costs. Some models involve connecting to the power supply network, for example, to ensure the operation of fans and the functioning of the control units, but the consumption of electricity is minimal, and will not fall further for the family budget.

• The design of most gas heaters is quite simple, does not have complex nodes, which increases the reliability of such devices.
• Modern heaters have a very decent efficiency, that is, it speaks about the economy and efficiency of their work.

For some exceptions, gas heaters are distinguished by high mobility - they are small in size, easily moved to place in place, transported in the car. Many models can even take with them hiking, fishing or just when leaving for nature.

• The operation of gas heating devices causes minimal damage to ecology - the products of complete combustion of gas are practically harmless.
• Instruments, as a rule, are easy to operate.
• Warming up the premises is carried out very quickly - inertia in operation is not peculiar to such devices. For the same reason, gas heaters are very sensitive and quickly respond to changing settings.
• Modern products of this class are equipped with multi-level protection systems, which minimizes the likelihood of dangerous situations.
• Most devices are distinguished by enviable durability - they are able to correctly serve for 10 years or more.

Nevertheless, despite numerous "pluses", it does not do without negative sides:

• In any gas devices, it is impossible to completely remove the fire hazard problem, as the flammable fuel is used, and the work is accompanied by high-temperature heating. Such heaters require special precautions. It is unacceptable to leave them unattended if there are juvenile children in the house.
• By itself, the unlawful natural gas is very toxic, and any of his leakage can cause very serious poisoning, up to the saddest consequences. That is, it imposes additional safety requirements.
• The process of combustion of gas requires a constant inflow of oxygen, which in many models is closed directly from the room where the device is installed. And therefore - it is necessary to thoroughly think over the supply system and exhaust ventilationSo that the rooms are not created in uncomfortable, heavy, or even dangerous to the health of a person atmosphere. By the way, in the requirements for the organization of ventilation, it is directly referred to on additional volumes of air circulation, if the room is planned to operate gas appliances. And if, during water or electric heating, these questions sometimes look "through your fingers", then in the case of the use of gas heaters - a dismissive approach to ventilation is completely unacceptable.

What vents must be respected in a residential building?

This is not a celebrating question, and the requirements for ventilation are not taken "from the ceiling" - they are clearly regulated by applicable regulatory documents. You can read more about this in a special article of our portal dedicated to problems.

However, when properly operation Such devices become reliable and loyal assistants capable of quickly and efficiently create and maintain the necessary comfort in the country living conditions.

Well, now consider the main types of gas heaters in more detail.

Gas thermal guns

These devices are indeed remotely resemble an artillery tool - a large metal cylinder located on the "lafet" - stand.

Some of the most simple types Gas heaters. The principle of action is simple - a gas burner is placed inside the cylinder, and an ordinary electric fan is installed behind it, creating a directional flow of heated air flame. Electrical part gas gun can work from the network or from the battery. As a rule, such devices are designed to connect to a cylinder with liquefied gas (propane).

The advantage of such heaters can be called low cost and simplicity of the design. They are mobile - they are easy to rearrange right placeAnd for this, special handles on the cylindrical casing are usually provided.

Such devices are usually equipped with a piezoroca system. There are also certain levels of protection and safety protection. Thus, special sensors monitor the presence of a flame, behind the temperature of the case, for the content of oxygen in the room. In the case of an abnormal situation, the device will be automatically turned off with overlapping gas supply to the burner.

However, the disadvantages of such heaters are quite a lot. First of all, they are pretty cumbersome for residential premises. The direct burning of gas requires a large amount of permanent air, and combustion products are not particularly pleasant smell. In addition, the open flame is a big minus security.

Another significant drawback in the work of such heaters is a rather high level of noise. It can reach up to 70 decibels, which for a comfortable environment in the house is clearly a bit.

In short, in residential premises such heaters are trying not to use. But to warm up, say, workshop during work, garage, construction site or some agricultural painting is a very good option. Due to the directed hot flux, heating even large in terms of the size of the room will be ensured very quickly.

Ceramic gas heaters

But such devices can already be "put into the house." The level of safety of their operation is much higher, due to the other principle of heat transfer.

This device also has a gas burner, and it creates numerous, but very small flames that are heated not surrounding air, but a special ceramic emitter. He, in turn, heating to a very high temperatures (from 600 to 800 degrees) becomes a powerful source of infrared rays. Well, the advantages of infrared heating are known - thermal energy can be transmitted at considerable distances, without scattering in the air, but, absorbing optically opaque objects (including human body), cause their heating. Well, the heated items, in turn, including, for example, walls, floor, ceiling, furniture, etc., will "share" heat, through direct heat transfer, with air indoor air. No fans, that is, the device's work is distinguished by almost complete silent.

Such devices can be connected to a network gas or work from a gas cylinder. By the way, the design of the case of many models provides for the hidden placement of a standard cylinder in it.

The range offered on sale heater of this type is very wide. Moreover, the models can differ and sizes and power, and external design, and the way they are installed in the room.

So, you can buy a completely miniature heater, almost almost a desktop execution, with a little gas cylinder Inside. Such a device is suitable for creating a local heating zone, for example, in the place of traditional holidays.

Ceramic heaters can be completely "tiny" - practically, desktop execution

For full-fledged room heating, more "monumental" devices of the outdoor location are used, by type of those shown in the illustration above.

The installation of heaters of a similar principle of action on the walls and the ceiling is also practiced - they have a specific form of a housing that provides directed flow infrared heat in the specified sector.

Such devices are very effective both for complete heating of the room and to create "high comfort zones. True, ventilation for them still will have to ensure - combustion of gas, one way or another, requires the inflow of oxygen.

The security system, in addition to the above-listed protection steps, also also turns off the device in case of tipping it. That is, the risk to overheat, for example, the surface of the floor with an inaccurate circulation or due to the fault of accelerated children is minimal.

Gas heaters of the catalytic principle of operation

This type of gas heaters can be safely called the safest in operation. The fact is that there is no open flame here - the oxidation of gaseous hydrocarbons occurs on a chemical basis, due to special fiberglass heating elementin which the thinner platinum spraying is used as a catalyst that provides the desired reaction. Be that as it may, it is still the process of "combustion", that is, oxidation, with appropriate heat generation.

With this gas combustion, the minimum amount of oxygen is consumed, which has a positive effect on the atmosphere indoors. The lineup - It is quite wide, and you can purchase as a heater for full heating is quite decent to the size of the room and the compact mobile version.

In principle, the devices of the catalytic principle of action could be considered the best option. The only drawback remains only a fairly high price for them - but this is due to the peculiarities of their production technology.

Stationary gas convectors

If permanent accommodation is supposed to be permanent, or from the city, even in winter are regular, then the best option The installation of a stationary gas heater of convector type will be.

Such heaters after installation become low-dimensional from conventional heating convectors. The same characteristic rectangular corps, "melt" on the wall, with slit holes below - for the receipt of cold air, and from above - to exit warmed up.

But inside, definitely, the device is different. There is a combustion chamber (most often - a closed type) and a heat exchanger, a cast iron or steel, through which the flow of heated air pass. Cast iron heat exchangers are considered more durable, but they are heavy and somewhat inert. Steel easier, and faster react to changing settings or to trigger the thermostat.

Most modern models have a closed combustion chamber, that is, the influx of air is carried out from the street, and the gas combustion products are directly thrown there, which is extremely convenient. In addition, such devices practically do not represent fire dangerSince the flame does not in contact with the air indoors. Air supply and gases are carried out through a coaxial chimney, derived out through the hole in the wall. This is, in principle, and predetermines the stationary placement of such devices.

Such devices are not particularly expensive, they are equally well (after appropriate reconfiguration) and with a network, and with liquefied gas. Stationary installation convectors proper selection Power may well serve as the main, that is, the only source of heat at any time of the year.

Disadvantages are small, and even that - very conditional. These are immobility of the device (as, otherwise and any heating radiator) and dependence on the presence of power supply required for the operation of the coaxial chimney fan.

The execution may be different - from laconic forms to decorative "screens", in which, by the way, the visibility of fire can be created, for greater painting.

There are gas fireplaces and with an open combustion chamber, but they are somewhat more complicated with them - it will be necessary to organize a full chimney. So for the country conditions, it is probably not the most convenient option.

Prices for infrared heaters

Street infrared gas heaters

Agree, it's nice to spend time in the evening outside in a family circle or friends. But sometimes cool weather simply drives into the premises, where the situation is not at all. But there is a solution and this problem!

We are talking about street gas heaters that are capable of creating and maintaining a comfortable atmosphere even in very cold weather in a certain radius. Such instruments are usually attached to a characteristic form, stylized by street lights or original highlighted columns.

There are similar heaters from liquefied gas, a cylinder with which, as a rule, is needless, as it is hidden at the base of the device. The block with burners and infrared emitters (usually - ceramic type) is transferred up, and has a reflector-reflector, which sends a thermal stream cone-shaped down.

However, a form may be different - for example, the emitter is located vertically, and the spread of infrared heat goes in the same side radially. There are instruments and aimedal action that spread the streams of radiant heat in a specific sector.

Devices are good for all - they are able to create a truly pleasant atmosphere even in cool weather. Everything is explained simply: the condition of comfort is not always depends on the air temperature - the direct perception of radiation infrared energy also plays a very large role. Remember the frosty sunny day - heat from the rays of the sun is very well felt skin. And in photographs from the Alpine resorts sunbathing among the snow, people are quite ordinary phenomenon. Exactly the same principle is used here.

Highly wide application Such heaters find in places of traditional recreation, such as open terraces of cafes and restaurants. To have such a device at home - very expensive pleasure, and they are found very rare in everyday life. But if a family celebration or a meeting of friends is planned, then, judging by the ads, there is an opportunity to rent on the evening-other. This practice is distributed, and for small money you can organize a comfortable picnic in the air.

"Hiking" gas heaters

About the heaters of this type already mentioned above. They can be of a different type, but combine their small dimensions and weight, that is, instruments have exceptional mobility.

Many models of gas reservoir are placed inside, very compact, by type of aerosol cylinder. Other devices are connected through the hose to the standard cylinder of a small capacity.

It is quite possible to warm the air in the tent in the evening in the tent in the evening at night, set it from being cold. Often use them and in domestic workshops if one or another work is required in winter. Some models have another interesting option "option" - a well-thought-out system of supports and brackets allows you to turn the heater into the gas tile on which you can quickly boil the water or cook food.

In short, even if the heating issues do not cost such a sharp, to have such a small gas device in the economy - probably will never be superfluous.

What is estimated when choosing gas heaters for giving

If it was necessary to purchase a gas heater for giving, one can be guided by choosing the optimal model with the following criteria:

• First of all, it is necessary to clearly formulate yourself, for which the device is purchased. Agree that heating the residential room, a household building, a garage or hiking "housing" - things are completely different. The main purpose of various types of devices has already been said, but several more advice will be appropriate.

If permanent accommodation is planned in the country, the gas convector of the stationary installation will be the optimal choice - it will ensure proper savings and constant maintenance of the required microclimate. But in the case when the nationality is carried out infrequently, it is undesirable to put such a device. First, it simply can "smoke". And secondly, he will not be able to the shortest time Create a comfortable atmosphere - with convection heating for this, a certain time is necessary. For such use, it is better to get a ceramic infrared heater. It is easy to lead in the trunk of the car, and heating from it in the sector of his actions begins to feel almost immediately - in this characteristic feature radiation propagation of thermal energy.

• The device in its power must comply with the planned use. It is useless to wait for miracles from a low-power compact portable heater - it will not be able to say to ensure the proper temperature in a spacious room. Yes, it is not created for this.

If the task of replacing the heater heating system is not worth it, and the device will only be used in the offseason, the "race" will be simply inappropriate. But in the case when the function of the main source of heat is assigned to the gas device, to acquire the model, guided by the principle "the more powerful - the better" is also not too a reasonable approach. The choice should be weighted - there is no point in to give extra money for excessive power, which or remains unclaimed, or from which the gas overrun will probably be observed and too hot the atmosphere in the premises.

How to approach the choice of power of any heating device (not only gas) - will be told in the appendix to this article.

• Frequently equipped with thermostatic regulators, with which you can specify the required temperature in the room. When the specified threshold is reached, the gas supply to the main burner is stopped, and will be resumed only after the temperature drops to a certain lower boundary.

It is very convenient, in addition, if the device has the ability to step or smooth heating power adjustment - or the number of burners involved, or the gas supplied to them is changed. Such options significantly reduce the consumption of "blue fuel", increase the durability of the heater, as it will mostly work in the "gentle mode".

• The degree of safety of the heater is necessarily estimated. It has already been said - the triggering of protection, that is, turning off the device during overheating, with oxygen insufficiency, when tipping, gas leakage and other possible abnormal situations.
• Dimensions, weight, mobility, that is, the presence of a wheeled trolley or carrying handles, external design - all this is at the discretion of the future hosts of the heater.
• There will be a perfect adventure to acquire such equipment from hand or in "not quite understandable" outlets. Oh neither cool, gas heaters are enhanced hazard devices, they should be, they must be the factory tests, which is confirmed in the product passport. In addition, the manufacturer's warranty will be valid only if there is an appropriate mark of a specialized store in the instrument documentation.
• Prices for gas household heaters have a very wide range - from 1 ÷ 3 thousand rubles for compact low-power models, up to 30 or more than thousands - for "trusted" devices. Here the financial consistency of the buyer is already on the fore.

Often it is operated by the ratio: 1 kW of thermal energy by 10 m² of room area with medium height ceilings in 2.5 ÷ 2.7 m. You can go on this simplified path, but not excluded serious mistake In one direction or another. The fact is that indicators required power Although not only on the size of the room - there are many other criteria associated with both the location of the house (for example, climatic conditions region of residence) and with the peculiarities of a particular room. Therefore, it will be advisable to carry out a more accurate calculation, taking into account these factors. Moreover, a lot of time such calculations do not occupy - for this we offer to apply a special calculator.

Supply installations with gas heating of the air of the company Sonniger

Air heaters are widely used in Moscow at modern enterprises and storage facilities. These are very effective devices that are capable of providing warm even the largest squares. In addition, such equipment can be used not only for the purpose of heating, but also for the ventilation of the premises and the withdrawal of malicious and caustic gases and evaporation.

In their way appearance These devices represent the heat-insulated panel of 2 sheets (internal and external) stainless steel with thermal insulation inside, a functional heat exchanger made of AISI 430 stainless metal, AISI 441, as well as a ventilation section with leading Nicotra / Gebhardt fans, the main task of which is to suck air For further processing and supplying the premises. Initially, it may seem that gas supplies are complex devices, but this is not the case, since each consumer can take advantage of this technique. By ordering such heat generators, you will no longer have to return to the question regarding the provision of your facility with comfortable conditions, since these installations will greatly cope with the mission entrusted to them.

By ordering the gas heat generator from us, you will for a very long period forget about the issue of heating your object, enjoying comfortable conditions for productive work.

As soon as the product data is not called, ranging from "fire heaters", "heat guns", simply "burners" and hereinafter - "Gas calorifers", " gas furnaces"," Hot (warm) air generators "," air heat generators ". The most common (faithful) name is the gas air heaters and, if you look from the supply of the supply installations, the gas sections of heating. What are gas air heaters? According to the air heating method there are air heaters using indirect heating of air (they are sometimes referred to as recuperative air heaters) and direct heating air heaters (so-called mixing type). Direct air heating is when there is no combustion chamber and heat exchanger (photo 1). The flame of the burner directly heats the air. Modern combustion systems make it highly efficiently burn natural gas, but when designing it is necessary to make a decrease in concentration. harmful substancesentering the room with combustion products, below 30% PDC. These aggregates are particularly effective at large lathes of air exchange, when the level of harmful substances released inside indoors significantly exceeds the level of combustion products from the gas air heaters of direct heating: foundry, welding workshops, etc. Range of thermal power 40-1500 (2000) kW.Due to the smaller metal componence, mixing gas air heaters are cheaper than recuperative, characterized by a large power range and lack of chimney, i.e. combustion products are immediately mixed with heating air - no need to think about condensate combustion products when working with negative temperatures Street air. Such gas air heaters are widespread in the United States, Canada, the UK. There are manufacturers in France, Germany and Holland. In Russia, it is still relatively rarely used, although we have several domestic manufacturers. The indirect heating is when air (recycling and / or dying) with the help of a fan (axial, centrifugal) is supplied inside the unit, after which it is heated, passing around the combustion chamber and through the heat exchanger, the products of the combustion are derived through the chimney (photo 2). Then the heated air, thus obtained, is produced either directly into the room or through the air duct system. Gas air heaters of indirect heating (recovery air heaters) in turn conventionally divided: 1. Air heaters with built-in atmospheric burner or air heaters with tubular heat exchanger (photo 4).
Schematic scheme (Photo 3): Atmospheric burner at the entrance, i.e. working under atmospheric pressure and consisting, as a rule, from several nozzles / injectors (similar to any home gas stove). Next, after a tubular (lamellar) heat exchanger at the outlet of the chimney fan, thanks to which the products of combustion and pass the heat exchanger. Advantages: simple design, So, the competitive price. Disadvantages: ❏ A small range of thermal power: 15-150 (200) kW, to provide greater thermal power, these heat exchange modules are installed in series and / or in parallel, which leads to an increase in the value of this solution; ❏ Difficulties if necessary to work in mode condensation of combustion products.
2. Air heaters (heat exchange modules) with an additional fan (inflatable, blowing) burner (photo 5). Schematic diagram: A fan burner is installed in the combustion chamber of the heat exchange module (i.e. with a fan). Thanks to the pressure generated by the burner, combustion products pass through the combustion chamber and heat exchange tubes (channels). Range of thermal power 40-1000 (1200) kW. A more expensive solution compared to the corresponding heat-powered atmospheric burners, but it is a more significant range by power, it is easier to solve the issue of the formation of condensate combustion products - it is possible to use diesel burners.Intermediate conclusion: At the moment, due to the small heat capacity range, gas air heaters with the atmospheric burner are advisable to use for small intake installations or monoblock (roof - roof top) of air conditioners. For large central air conditioners and aircraft installations, more competitive gas air heaters (heat exchange modules) with an additional fan burner. Further details about the embodiment of the gas sections of heating consisting of a heat exchange module (air heater) and a fan (inflatable) burner. Materials used to make a heat exchange module The heat exchange module under the fan burner conventionally consists of a combustion chamber and the heat exchanger follows it. Most manufacturers use the following materials. The combustion chamber is performed from AISI 430 stainless steel (GOST - 12X17) when working with air, heated maximum to 120 ° C. For combustion chambers and various compounds during air heating to temperatures from 120 ° C to 280/300 ° C and with the degree of air heating (Δt), more than 80 ° C uses heat-resistant stainless steel AISI 310 (GOST - 20X23N18). Sometimes at different pressures and air temperatures, various steel thickness for combustion chambers are used. With the exclusion of condensation of products The combustion inside the heat exchange module of the heat exchanger pipe can be made from carbon steel, for example, from steel S235JR (GOST - ST3SP) or aluminized steel. In case possible condensation products Combustion in the heat exchanger It is necessary to acquire an air heater with an acid-resistant stainless steel heat exchanger: AISI 316 (gOST - 08X17N13M2), AISI 441 (no analogue in GOST according to DIN X2CRTINB18), AISI 304 (GOST - 08x18H10) and on the extreme case of AISI409 (there is no analog in GOST according to DIN X2CRTI12), in which the condensate drain should be provided.
The phenomenon of the formation of condensate products of combustion directly in the heat exchanging module is due to the increased cooling of this module. With constant rated air flow, this can be caused by a low temperature of the supply air or a decrease in the thermal power of the burner below 60-65% of the nominal at work per 100% but recycled air. One way to reduce the volume of condensate combustion products inside the heat exchange module is an organization of a bypass line, working depending on the temperature of combustion products in chimney (photo 6). What gases can be used for gas air heaters? There are so-called liquefied petroleum gases, i.e. Gases which are associated with oil mining. Or more often they are called liquefied hydrocarbon gases (SUG): propane ( symbol G31, C3H8 chemical formula) and butane (G30, C4H10). These gases are also called heavy hydrocarbons, propane and butane, in contrast to natural gas, heavier than air and during leaks, they are more explosive, because Do not destroy, and make up the floor, fill the niches. It is a mixture of propane-butane sold for household needs in the cylinders in retail. Almost any gas burner when replacing the nozzle (membranes on the gas valve) and the reconfiguration can work with liquefied carbon gases.In principle, on any facility you can make a gas station with tanks under Sug (GasGolder), but because Liquefied petroleum gas is not fundamentally cheaper than diesel fuel (one and a half times, while natural gas is cheaper than seven-time diesel fuel, according to experiences for industrial facilities, this is a very rare option, so you do not stop more on it. There is another exotic version - liquefied natural gas, i.e. Liquefied methane. Liquefied natural gas (LNG) - cheaper than land, but because We have a major emphasis on gas pipelines - objects that use LNG are unique in Russia. Finally, consider the most common case: Natural gas - methane (G20, CH4). Gas pipelines (gas networks) under natural gas are divided: ❏ Low pressure gas networks - up to 0.05 kgf / cm2 (50 mbar or 5 kPa); ❏ average pressure - from 0.05 to 3 kgf / cm2; ❏ High pressure - from 3 kgf / cm2.
For various types of rooms, you can use various gas pipelines. In our case, we will talk about the gas pipeline of medium or low pressure. The inlet pressure of natural gas for atmospheric and premix burners is only low (20 mbar), for them, as a rule, when connected to the gas pipeline, use additional reduction gearboxes. Inlet pressure in fan burners (photo 7) may be different depending on the gas ramp used (multiblock). The lower range depends on the characteristics of the ramp and the heat exchange module (combustion chamber), often it is 20 mbar, the upper threshold depends on the diameter of the gas ramp (the characteristics of the gearbox integrated into it) and usually this is a fixed value (100, 360 or 500 mbar). That is, fan burners can work with low (up to 50 mbar) and with an average pressure of natural gas (from 50 mbar). Air heaters (heat generators) with an additional fan burner can also work using diesel burners. Or can be used combined burners, working alternately and with gas and with diesel fuel. In fact, if there is no frequent change of the type of fuel, the object must first be launched on diesel fuel, and later translate to natural gas, because it is much cheaper to first put a diesel burner, and later buy a gas burner than to immediately purchase a combined one. Projects with diesel burners, probably, on average one by 30 gas, so the nuances of the fuel pipelines are lowered under diesel fuel. The main feature of such projects for the intake installations, i.e. Projects When using the diesel burner under consideration, it is necessary to avoid working in the condensation mode of combustion products. Gas and diesel fan burners, automation air heaters (heat exchange modules) can only be equipped with certified gas or diesel fan burners. Depending on the task, such burners may be: single-stage - operate on one fixed power; Two-stage - operate on two pre-installed power values \u200b\u200b(low and high); Modulating - the power of its operation can smoothly vary from minimal to maximum values.The selection of burners is carried out by the power of the heat generator and the oppression created in the combustion chamber, in addition, it is necessary to consider the length of the burner nozzle. The length of the burner nozzle must be in the range specified by the manufacturer of heat exchange modules. Air heaters (heat exchange modules) are equipped with a thermostat unit that provide the internal logic of the operation and the safety of the heating section, but do not control the temperature in heated and / or deventive room. Automation for temperature control indoors (in the air duct) is a separate question depending on the task and the burner used. Features of the accommodation of aircraft installations with gas heating 1. When placing indoors (photo 8). If inside the heated room - see the NPB 252-98 "Thermogenerating devices operating on different types Fuel. Fire safety requirements. " If in the ventilation chamber (photo 9) - Looking for placement, see SNiP II35-76 * "Boiler Settings" .2. Street performance. The easiest option from the point of view of coordination / norms, but there are nuances by execution. Also do not forget about the features of the maintenance of "outdoor air". Standard (typical) European floor air heat generators (air heaters) in case of street execution are calculated for long-term reliable operation at temperatures up to -15 (20) ° C. The burner automation allows it to be turned on at temperatures not lower than -15 ° C. In this case, usually the burner and electric shield simply close the casing from the sandwich panels (photo 10). In most cases, this is enough, because The burner when working heats himself and the space around. There are examples when even such standard execution normally serves in the most complex climatic Russian conditions for more than one year.
In photo 11, an example of a more thorough execution of the gas air heater section is presented in the event of its street location. Section with burner is isolated not only from above and on the sides, but also from the bottom. For ventilation section (air intake on burning) lattices are made. In the regions where there can be particularly low temperatures in winter (below -30 ° C), it is necessary to need additional heating of the burner section. Most often, an additional unit is installed inside the burner electric heater, sometimes they make the flow of warm air into the section with a burner from heated room or from ventilation canal After heating air. When it is advisable to use gas air heaters in the general case Gas air heater (i.e., the supply unit with the heating gas section) is more expensive in capital expenditures of a similar installation with water (electric) heating, but, on the other hand, the gas air heater will always be cheaper than a bunch "Boiler room + water supply installation" similar thermal power.Accordingly, gas air heaters are most competitive when there is no parallel large boiler room (heating mains), and a small boiler room is used, let's say, for some small ABC (office center) and / or DHW (photo 12). It is based on gas air heaters Unified air heating and ventilation system: production premises, warehouse, shopping complex, cinema or gym. As a rule, in this case, mixing chambers (air heaters) are provided for mixing chambers for simultaneous operation with supply and recycled air. Maybe? To pump and / or ventilate especially fire-hazardous premises due to the supply of overheated 100% air intake air, but such installations are complex and roads. Initially, the main purpose of gas air heaters is air heating. Gas air heater in pure mode supply installationthat decisive only the task of ventilation is used for the premises of heated gas infrared heaters ( radiant heating) or mounted gas air heaters (Gas AVO). Currently, several types of aggregates with gas heating are presented on the market. The first type is floor heater heat generators (gas air heaters). Such devices consist, as a rule, only from the heat exchange module and the fan sections. The second is the monoblock roofing conditioners (in English they are called ROOF TOP), which, in addition to the cooling section, can have a heating section on water, electricity or gas. Finally, the third is custom-made supplies and aircraft installations with a gas section of heating. It is clear that the use of standard solutions is lower capital costs, but sometimes the only acceptable option is custom installations, equipped, for example, sections of recovery, humidification and other additional equipment. We consider it a revealed on this topic, some nuances are better to clarify from the profile specialist.
