Best automation for gas boilers. Principle of operation of automatic gas boiler

Automation for gas boilers heating

Automation for gas boilers of heating can not only provide different modes of operation, but also the required level of security during boiler operation. Various sensors, control unit provide the necessary operational properties of boilers.

Automation of gas boilers implies the presence of such sensors as:

Combustion sensor;
Water level sensor;
Purge sensor;
Coolant temperature sensor.

Such equipment is necessary to ensure the following points:

Gives control signals to the ignition transformer, on the solenoid valve and the fan.
In case of unsuccessful ignition, automation for the heating boiler will disable gas supply. Also, the prohibition of fuel supply will take place in case of insufficient air power supply or if the fuel is poor quality.
During the functional troubleshooting of the device, the automation will supply the "Alarm" signal.
If the coolant in the heating system does not correspond to the norm, the ignition will also be prohibited.

Automatic control of a group of heating boilers

Automatic control unit can be purchased to order. Automation for electric heating boilers is used for group heating by multiple gas boilers. The maximum number of boilers should not exceed 6 devices. All boilers must be connected to the same heating system. Such blocks are best suited for boilers, where it will not be necessary to constantly be personnel.

The operation of such devices is carried out in accordance with the data:

The air temperature inside the boiler room (measures the thermometer for the heating boiler);
Water temperature in the collector;
Parameters specified by the Operator buttons.

Through automation, a certain temperature of water is maintained in the heating system during the operation of the aggregate.

The temperature can be installed independently in manual mode, it can also be installed automatically. For this serve thermostators for heating boilers. Such a device as the thermostat for the heating boiler will monitor the temperature regime of the room.

Automation for steam-type heating boilers is used for the same goals as in the boilers of another type. It not only allows you to control all processes, but also provides due security. Automation allows you to regulate all processes in an independent way, without participation in them.

Automation of steam boilers heating

Automation of steam type boilers implies the presence of systems such as the water level converter. Its functions are:

adjusting the water level in the device;
playing a signal that turns off the burner if the water will be lower or higher than the level of permissible norm;
valve for purging a continuous type;
electronics device;
valve for rapid purge;
a system that can control purge through programming.

Such systems are carried out both control of the operation of the device and the level of security.

Pellet boilers

The boilers of this type differ from the analogues in that it uses such fuel as pellets. This fuel is granules, manufacturing material for which is the usual wood. This material, so to speak, is manufactured by recycling. Pellets are made of wood sawdust or chips. Such material practically does not represent any value, so its use is quite acquitted in these purposes.

Pellets are relatively inexpensive, therefore pellet type boilers enjoy quite great popularity.

The principle of functioning of the boilers of this type is as follows:

They are able to maintain a certain temperature mode;
Fuel supply occurs in automatic mode.

The basic set of pellet boilers suggests the following components:

Boiler;
The bunker from which pellets are served;
Automatic burner.

Boilers differ not too complex device, and for their work the presence of a person is not mandatory. These devices have a high efficiency of the efficiency, as well as quite economical.

Smart boilers

Those users who have a smart home system know also about devices such as smart heating boilers. These modern devices have different systems for automatic work, security, adaptation to external factors. Programmers for new generation heating boilers electronically regulate power - that is, the modulation of the flame burner is continuously with the optimization of the equipment, so that the fuel is inherent.

The control of the heating boiler will be made by digital appliances. Also provided for remote control of the boiler heating.

To improve the comfort support system, the climate control unit is connected to the heating boiler. Usually such a heating boiler controller is a digital week programmer to which the temperature sensor is connected. Thermal sensors for boilers of heating of this type smoothly change the temperature in the premises depending on which temperature on the street. GSM Module for heating boilers allows you to control the equipment remotely.

The presence of devices such as thermostats for heating boilers are convenient and efficient. Indeed, in modern heating systems, the thermostat for the heating boiler smoothly adjusts the temperature in your premises, depending on the external conditions and wishes of the residents.

Household heating devices operating on liquefied or natural gas do not require constant attention and control. This task is performed by automation for gas boilers heating.

Electronic and mechanical control units integrated into the heat generator adjust the combustion and help maintain the required temperature in the coolant.

The automation works properly, clearly and reliably, increases the efficiency of heating equipment, promotes the reasonable consumption of the energy resource and performs the operation of the heating system is simple, comfortable and absolutely safe.

The automatic system protects the heating plants from overloads and activates the emergency shutdown of gas supply in the case of sudden force majeure. Additionally, the technique regulates the level of burning intensity and current fuel consumption, allowing the owners to save funds on the heating of premises.

The automatic node has flexible settings and allows the owner to set the equipment as easy as possible for themselves.

According to the basic principle of operation and constructive features, automation for gas operating equipment is divided into:

devices with energy dependence;
energy independent devices.

The first-type systems are complex electronic aggregates and for correct operation that need uninterrupted electrician feed. The second types of devices are simplified mechanical structures that do not require energy feeding.

View # 1 - Energy-dependent products

Energy dependent module - This is a small electronic device reacting to the supply of fuel resource. Turns on and turns off at the moment of activation or closure of the main gas crane. Differs complex design and large number of elements and chips.

Allows the owners to solve the following tasks:

activation or termination of gas supply;
running the heating system in automatic mode;
adjustment of the power level of the basic burner (due to the presence of the thermostat);
turning off the working boiler both in emergency situations and within the framework of the user specified mode;
the output of current indicators on the display (the overall level of air temperature in the room, the mark, which is heated by the working heat carrier, etc.).

More "tricky" modules have additional functionality and offer users unlimited and most convenient conditions for monitoring the operation and control of the unit. Electronic panels provide full protection of heating equipment from a malfunction and do not give the boiler to freeze.

If the room is sharply lowered the temperature, the "smart" system itself launches the heating equipment and turns it off when the dwelling is filled with comfortable warm air.

The independent diagnostic option available from individual modules warns failures in operation and contributes to the timely detection of faulty parts and nodes in the system. It makes it possible to remove the breakdown as soon as possible and replace some small element before it creates a real problem for the equipment.

Small breakdowns of the heating system in the end turn into global difficulties and entail cash spending related to the repair and dismantling (full or partial) equipment. Independent diagnostics helps to identify a malfunction and makes it possible to eliminate it in a timely manner.

Electronic automation, which is responsible for the safe operation of the equipment, ensures the smooth operation of the boiler, does not allow the system to overheat and overlaps the gas supply in the event of a drop in the thrust or attenuation of the flame in the burner.

The assortment line of energy-dependent automation, presented today on the market, pleases the diversity. Useful and necessary mini-aggregates produce brands famous for the whole world and small companies, only trying to win their place under the sun.

Energy-dependent automation is presented in the form of control panel, where the user can set user-friendly parameters of the equipment. The cost of a "smart" element is high, but the cost is justified, because using the control unit you can reduce the consumption of the resource without any damage for your own comfort.

Among the proposed models there are both completely simple products and more advanced units with the programming option.

On them, the user can choose the most suitable for themselves and program the system to work in the day / night mode or, focusing on the weather forecast, set a certain level of warm-up at home or apartment for a period of 1 to 7 days.

View # 2 - non-volatile aggregates

Non-volatile automation More simple and practical. Management and setup are carried out manually with the help of mechanical rotary togglers and do not represent difficulties even for those who are far from the equipment. The device works absolutely autonomously and does not need to be connected to the central electrical system.

For the heating of a residential building and supplying hot water to the cranes, the control knob is enough to turn in the direction of zoom to 2-3 divisions. If you want to take a bath or shower, the toggle switch must be installed on the maximum indicator

The product is marked with a digital scale with a list of values \u200b\u200bfrom the minimum to maximum. To activate, the user selects the desired mark and this way sets the appropriate operating temperature directly to the boiler.

After these manipulations, the specified warming mode is connected and takes control. The boiler works actively until the room warms up to the desired temperature. Then the temperature turns off the gas supply to the system and activated again only when it becomes colder in the room.

The principle of operation is based on the specific design of the device. The thermocouple-built gas boiler thermocouple is equipped with a special rod. It is made of a special iron and nickel alloy called Invar.

The physical characteristics of this progressive material emphasize its ability to almost instantly capture the minimum temperature fluctuations.

If the room becomes overly hot or too cold, the size of the rod changes. This reacts the connecting valve and overlaps or activates the flow of gas in the burner.

The presence of a non-volatile automatic control system allows users to install in the house or apartment the most suitable temperature regime and economically spend the fuel resource, without overpaying by utility bills

Additionally, the automation of non-volatile type has sensitive. If the pipe or the level of thrust in the chimney suddenly decreases in the pipe for some reason, the resource is immediately stopped and the gas leakage can be avoided.

Non-volatile automation costs quite reasonable money and, unlike electronic analogs, does not require the purchase and installation of a stabilizer controlling voltage and leveling unforeseen jumps in the central power grid

The correct operation of the flame sensor provides a special plate. With the normal and proper functioning of the system, it is in a slightly curved state.

In this way, the part holds the blocking valve in " Open" When the flame becomes less, the plate is aligned and the valve under its pressure is closed.

Construction and principle of operation

Automation, managing, consists of many elements, conventionally divided into two subgroups. The first includes mechanisms that ensure the full and safe functioning of the boiler itself. The second includes devices that give the opportunity to operate the heating system as convenient and comfortable for the user mode.

Components of security system elements

Several modules are responsible for the operational safety of the aggregate:

Flame Controller - consists of two main parts - electromagnetic valve and thermocouples. In a timely manner and reliably overlaps gas and prevents the formation of leakage.
Thermostat - supports the desired temperature of the coolant and protects the system from overheating. When the coolant cools up to minimum temperatures, the module starts the boiler to work, and after fixing peak-high indicators, it turns off it, completely eliminating the owners from the need to constantly pay attention to the system.
Sensor controlling cravingis responsible for the cessation of gas supply to the burner in the event of a change in the basic position of the bimetallic plate, preventing the gas leakage in this way.
Safety valve - monitors the amount of coolant in the circuit.

In addition to all the above useful qualities, the automation has a number of additional functions that improve the comfort of the use of equipment.

The device performs auto-line gas burner, selects the most efficient working mode, contributes to the rational consumption of energy resources and conducts independent diagnosis, eliminating the owners from all these classes.

Principle of operation of automation security

Current regulatory documentation says that the gas boiler safety complex must be necessarily equipped with a device that stops the operation of the entire system and overlapping gas supply in the event of an unexpected breakage or any more force majeure.

To implement this task, the automation should keep such parameters under control as:

gas pressure in the system;
the presence of an optimal flame in the burner;
full, high-quality traction;
the temperature level of the working coolant.

When in a non-volatile mechanical system, the gas pressure drops to a critical level, the feeding of the resource immediately stops. This happens automatically due to the presence of a valve mechanism configured to a certain value.

Energy-dependent electronic devices are constructed somewhat differently. In them, the function described above provides a minimum / maximum pressure relay.

With an increase in the amount of the atmosphere of the membrane with a rod bends, blur contacts of the boiler itself. Gas ceases to do and is not supplied until the pressure level is restored.

Alone to troubleshoot and somehow interfere in the basic functionality of the equipment is prohibited by law. Correct any problems that may only have a qualified specialist - an employee of a gas supply company

If the flame disappears in the burner, the thermocouple cools and ceases to produce the current. After that, the electromagnetic flap in the valve is no longer functioning, and the gas ceases to flow to the burner. When the thrust falls, the bimetallic plate is intensively heated, changes the shape and affects the valve, forcing it to stop the fuel supply.

The temperature of the coolant keeps the thermostat under control. It provides the maintenance of the heated mode selected by the user, while not giving the system to overheat and fail.

Nuances of system functioning

Energy-dependent electronic automation in the work is based on information obtained from sensors. The microprocessor and the internal controller analyze this data, processed and submit to the system system, optimally suitable for a single concrete situation.

In order for the electronic automation to function normally for a long time, it is necessary to call the wizard annually to inspect the equipment, diagnostics of the microprocessor and viewing the memory module reports

Mechanics have a somewhat different principle. When the boiler is turned off, the internal gas valve is completely blocked. At the time of launching the equipment, the washer on the valve is squeezed and the forced opening of the passage for the fuel resource to the stobble occurs. Razhigig stimulates the heating of the thermocouple and the voltage is on it.

This resource uses an electromagnet that supports the valve in the open position. By turning the puck manually, the user can adjust the level and power of its heating equipment without any effort.

Overview of popular models and manufacturers

In the market of progressive gas equipment and related elements, automation of both domestic and foreign manufacturers is presented. According to the principle of operation, all devices are absolutely the same, but there are significant differences in the structural plan between them.

The presence of control automation in the gas heating system makes it possible to comfortably heat the room and rationally spend the energy resource. With a reasonable approach, savings can range from 30 to 43%

The cost of modules varies in the wide range. Simple mechanical products with minimal functions belong to the class of budget and sold at the lowest price. Advanced electronic panels are much higher, but provide the user more detailed features for individual settings and control.

Some devices, such as automation of SBK, in addition to the basic functions, are supplied with a built-in pressure stabilizer. This allows more accurate adjustment of gas equipment

Electronic devices with the ability to program are considered suitable. They enable the owner to ask the equipment plan for a long period of time, taking into account seasonal weather conditions and the current air temperature on the street.

The operation of any heating boiler should be based on constant and uniform fuel supply. This is especially true of gas equipment, because gas pressure problems in domestic feeding networks are evident. That is why it is so important that all the processes, and especially behind the gas supply of the burner, followed the automation for gas boilers.

Varieties of automation

All that today is produced in the category "Automatic control systems for heating boilers" is divided into two groups:

Energy dependent.
Non-volatile.

Attention! The first operates from electricity with a voltage of 12 V. The second no energy is necessary.

Energy-dependent automatic instruments

Energy-dependent automation for gas boilers is electronic devices that mainly adjust the supply of gas by opening or closing the crane. This is a rather complicated device that producers are endowed with additional features. So, what can an electronic automatic network?

Close or open fuel feed faucet.
Run the boiler in automatic mode.
Adjust the power of the burner using the installed thermal sensor.
Stop the work of the boiler in case of emergency situations or in the case of a programmed mode.
Show visually, how the boiler itself works, to which temperature of the height of water and so on.

Currently, many manufacturers went further, because the requirements for the convenience of gas boilers are all rising. Therefore, modern electronic automation can additionally:

Control and manage the work of the pump.
Protect the heating system from freezing. In this case, the automation can quickly launch the heating boiler if a sharp decrease in the temperature indoors has occurred.
Protect the heating system against the failure of the three-way valve.
To conduct independently diagnosing heating and identify malfunctions of elements and parts.

That is, it turns out that this species is automatics of gas boilers. It is these electronic blocks that guarantee that the heating device will work smoothly, without jumps, by observing the exact temperature mode, and do not create problems in the process of long-term operation. I especially wanted to draw your attention to the diagnostic system. With it, you can prevent big faults. If they do not prevent them in time, then you can safely save on the overhaul of equipment.

Electronic unit automation

Currently, in the market you can purchase various automatic devices of energy-dependent type. It can be programmable blocks or ordinary without software control. The first is convenient in the way that it is possible to set temperature regime for a long time. In this case, the range is 1-7 days. Knowing the weather forecast, you can set the temperature for each subsequent day, thereby saving a comfortable temperature inside the house. By the way, using such blocks you can program the temperature of the day-night.

Non-volatile

This type of automation includes mechanical instruments of control and regulation of gas combustion processes inside the heating boilers. When a choice between two groups of automatic systems, many consumers choose the mechanical option. Why?

First, it is the cheapest designs.
Secondly, they have a manual setting, which makes it possible to understand the regulation processes of even the most distant people from these instruments.
Thirdly, this is the autonomy of the blocks, because for their work there is no need to connect to electrical networks. Even if for some time the electricity will be disabled, the boiler will simply adjust.

What is the essence of manual setting. The device installed a temperature scale from a minimum to a maximum. By installing the regulator arrow to the temperature you need, you and ask it to the boiler. After the boiler is burning, the thermostat is entering into business. It is he who will control the temperature you specify, closing or opening the gas supply faucet. The thermocouple for a gas boiler, built into the heat exchanger, that is, directly touching the coolant, in its composition has a special rod made of material that quickly responds to a change in temperature. Typically, such a rod is made from Invar (iron and nickel alloy). Under the action of temperature, the rod increases in length or decreases. It is firmly connected to the valve, which under its action adjusts the supply of fuel to the burner.

Currently, the manufacturers of gas boilers to the mechanical automation unit are added two sensors:

Sensor thrust.
Flame sensor.

Both devices are immediately disconnected by gas supply, if the chimney suddenly fell or the pressure in the gas pipe dropped sharply. Their device is based on bending thin plate made of alloy two metals. For example, at high temperatures, the plate is strung out and thus holds the valve in the open state. As soon as the flame has become less, the plate comes in a direct state, thereby overlapping the valve. The same itself occurs in the chimney with the thrust sensor.

Mechanical automation unit

Automatic multiblons

Scientific and technical progress gives us today the opportunity to use devices having compact dimensions, but with great functionality. Automation of gas boilers did not remain aside. Today manufacturers offer multiblons, which include:

Combined type gas valve.
Temperature regulator.
Thermal sensor.
Sensor thrust.
Device stabilizing gas pressure.
Valve for the burner. Usually this device has a two-stage effect.

Pay attention to the first valve. It works in a bundle with a thermostat, which with the help of a thermal sensor controls the temperature of the coolant directly in the heating circuit. Such a mini can work in a pair with a thermostat that is installed indoors. The latter controls the air temperature, and, accordingly, the temperature regime of the house. Such a bunch helps more accurately carry out the operation of the gas heating boiler.

Installation methods

Wired.
Wireless.

What is the difference? Already from the very name, you can guess that wired automation blocks are connected to the boiler using cables or wires. This is especially true of thermal sensors and thermostats. Not the best option if it comes to installation in the ready-made home. To install them will have to make wiring: hidden or open. If the hidden option is selected, then you will have to stick the walls. And this is no one unnecessary expenses. The wireless version is the best solution, but it is more expensive than the first one.

Do not forget to rate the article.

Gas heating boilers are high-risk devices. If irregular operation or malfunction, they can cause natural gas poisoning, combustion products, cause a fire or even an explosion. That is why all the processes passing in the boilers should be carried out under constant control, which is responsible for gas automatics for boilers.

Construction and principle of operation

All components of automation used in heating systems can be divided into two large groups:

Devices that ensure the right and safe operation of boiler equipment.
Devices that increase comfort when using the boiler.

In automation of gas boilers, it includes:

In some models of boiler equipment, the manufacturer provides for the presence of an instrument for removal of air. All devices incoming an automatic security system are non-volatile or mechanical. In the presence of actuators and the controller controller, they can work under electronic control.

Automation for comfort provides the owner of the installation Additional functionality: Auto-line burner; The functions of self-diagnosis and the choice of the optimal mode of operation, the modulation of the flame, etc., this type of automation is not mandatory and in some models does not apply.

The principle of the electronic security system is based on the acquisition of data from sensors that are processed by a microprocessor controller. Based on the data received from sensors and sensors, the controller submits the command to actuators actuators.

The principle of operation of the mechanical automation of the gas boiler Consider in more detail. The heating installation does not work - the gas valve is blocked. For the start of the boiler squeezes the washer on the valve. This operation is forcibly opens the valve, the gas enters the stall. After the ignition of the stamp is heating the thermocouple. It produces sufficient voltage for the operation of an electromagnet, which holds the gas valve in the open state.

The root of the washer is set by the necessary power of the boiler: the gas with the right pressure goes to the burner - there is a ignition from the stobble. After starting the boiler installation, control over the temperature of the coolant takes on the thermostat.

https://www.youtube.com/watch?v\u003dVek4DSO3B9Y For this principle, almost all security systems of boiler equipment are operating, regardless of the brand. When choosing this system for the boiler, it is recommended to pay attention to the instrument of the same brand as the boiler. For example, the automation for BOSH gas boilers is best looking for this particular brand.

Functional safety system of heating installation

Under the control of automation there are all the important processes that occur in the boiler. Automation for gas heating boilers ensures control over:

Gas pressure. When falling below the allowable value stops the supply of fuel to the burner. This happens in automatic mode due to the valve mechanism configured to a certain fuel pressure. In energy-dependent safety modules, the maximum and minimum pressure relays correspond to the gas pressure. These devices consist of a membrane with a rod. With increasing pressure of the membrane, the membrane is strung out and opened the contacts of the boiler installation. When pressure is normalized, power contacts are installed in a closed position.
The presence of a flame in the burner. In the absence of a flame, the thermocouple cools and stops producing the current required for the operation of the electromagnetic flap of the gas valve, which overlaps the fuel supply to the burner.
The presence of thrust in the chimney channel. With a decrease in the traction, the bimetallic plate of the sensor heats up and changes its shape. The thrust connecting the plate of the sensor with the valve displays it from the working state and the gas supply to the burner stops.
The temperature of the coolant in the circuit. The thermostat is responsible for preventing overheating and maintain the temperature of the coolant in the circuit.

Almost all modern security systems are equipped with control sensors and the presence and pressure relays of the coolant in the system. This type of automation is most often implemented in volatile systems. Any automation can fail for reasons of low quality, improper operation and maintenance. Next, you can familiarize yourself with the characteristic malfunctions of the automatic boiler and the methods of their independent elimination.

It should be known that independent interference in the design of gas installations is prohibited by law. That is why we strongly recommend that in the event of malfunctions in the heating installation, refer to specialists who have a state certificate for the right to conduct data.

Having retreated from the topic, we want to report that we prepared comparative reviews for gas boilers. You can familiarize yourself with them in the following materials:

Most popular security systems for boiler equipment

Today, the Russian climate technology market has more than a dozen automatic models from different brands. The popularity of one or another brand depends entirely on the demand of the heating installations of the same brand. Many owners of domestic boiler equipment are asked how automatics works in the Gas Cotelet Lemax? These installations use Evrosit automation from the Italian manufacturer. It is this automation system that is in the first place in popularity among domestic manufacturers of heating devices.

The models of this line have a good functionality and easily integrated into almost any design of the boot. Standard functions: gas pressure control; control over the presence of a flame in the burner and on the stall; Control over the temperature of the coolant and the chimney burden. The use of automation of this brand does not cause special difficulties from the owners, but requires some skills.

Before starting the device, you must press the adjustment and ignition knob and simultaneously with this Piezoelement button.
After the ignition of the ribbed, it is necessary to hold the handle pressed from 5 to 10 seconds, for heating the thermocouple.
If, after pressing the handle, the stall is not a wig, you can switch to the rotation of the washer, to adjust the gas pressure. After that, the main burner is ignition.

The automation of this brand is quite widespread in the Russian climate technology market due to a relatively low cost, good functionality and a wide model range. Standard functionality: maintaining the temperature of the coolant in the range from 40 to 90 ° C; control over pressure and fuel supply; automatic stop of the device in the absence or occurrence; Control over the presence of a flame in the burner.

Rostov products today are in demand by domestic users on a par with European automatic models due to its reliability and low cost. The functionality of automatic AOGV systems is also rich enough. The standard features of this technique allow to stop the operation of the boiler unit when the following situations occur: excess of the temperature of the coolant above the set level; Flame breakdown in a stall and burner; low pressure and absence of heat carrier in the system; any failure in the gas supply system; reduce fuel pressure below the established norm; In the absence or insufficient thrust. How does the AOGV gas boiler automatics work? The operation of the gas valve occurs due to the voltage, which produces a thermocouple. It is this tension that acts on the valve coil and keeps it open while the burner is burning. The temperature regulation occurs due to the thermostat and valves, which, when increasing or decreasing the temperature, open or overlap the fuel coming on the burner. Control over the removal of exhaust gases is carried out by the thrust sensor. Make the right choice of automation for gas boilers is quite difficult. We strongly recommend to seek help to professionals.

All about automation for gas boilers

Each gas heating system in a private house or urban apartment has individual specifications and features. Gas boilers differ not only by functionality and principle of work, but also the control system. For security purposes, all models of gas boilers are equipped with devices and devices for automatic adjustment of heating equipment. To obtain a more complete presentation of autonomous heating in the house, you should figure out how the automatic boiler system works, and which types of such devices exist.

The heating gas boiler is a complex engineering and technical product, during operation that requires constant attention. Automatic control is capable of providing the necessary control of the parameters of the boiler, making the heating system to truly autonomous.

What is automation for a gas boiler. General view

The automation used for gas boilers is special devices that ensure control of the operation of the heating equipment after it starts. The main purpose of automatic control devices is to ensure the safety of the operation of heating units and maintain the optimal temperature regime in the room.

By functionality, the automation is divided into two main types:

energy-dependent devices;
non-volatile control devices.

The first type is an energy-dependent automation used in autonomous heating systems, has a simpler design and works on the residual principle. The thermal sensor signal about temperature changes is entered on the electromagnetic valve, which is closed or opens, overlapping the gas supply to the gas boiler. This type of control equipment is equipped with almost all boilers of heating.

An example of a non-volatile unit of the automatic gas security system of the gas-beam type of automation - non-volatile devices operate based on the physical properties of the substance inside the closed contour of the device. When heated, the substance is expanding, creating increased pressure inside the device. Under the action of high pressure, a gas valve is operated, overlapping gas supply to the combustion chamber. The inclusion of the boiler is carried out in the reverse order. With a decrease in temperature, a decrease in the volume of the substance, as a result of which the pressure in the device decreases. The valve returns to normal position, opening gas access to the burner. Such automation devices are on the equipment of non-volatile gas boilers. Models of the automation system units may differ only with a regular set of functions.

The principle of operation of automation. Main nodes

Considering the internal device of automatic safety devices, it is possible to make an unambiguous conclusion that the main elements of the design are the safety and primary valves, overlapping the fuel supply to the work area or opening gas access to the combustion chamber. In this action, all automation for gas boilers of heating is built. Differences can only be available additional functions from automatic adjustment devices and ways to control them.

For example: You want to turn on the boiler. Razhigig is carried out as a result of gas supply to the power burner. This process is controlled by an electromagnetic valve. The installed thermocouple heated by the ignition burner is capable of a short period of time, only 2-3 s. Issue the necessary spark to ignite gas on the main burner. Ringing the ignition button, you run to work the main valve, which serves in the combustion chamber gas.

The device works due to the interaction of both valves.

Choosing the necessary air temperature for heated room, set the regulator to the desired position. Behind the entire process, the thermostat is clearly monitored, which is equipped with sensors governing the volume of incoming gas into the combustion chamber. Due to the two valves, shut-off and modeling, installed in the thermostat, the gas flow is regulated, therefore, the intensity of the boiler heating. The location of the main adjustment places on the instruments is about it in this way.

Note: The intensity of the heating of the boiler equipment can be adjusted by increasing or lowering the operating pressure on the fittings. The usual membrane is able to regulate the operating pressure of the household gas at the output. In another situation, adjust the output gas pressure in the system can be manipulated with a gas supply screw.

It is necessary to stop in more detail on what types of automation exist for home boilers on gaseous fuel, in which principle the operation of automatic devices is based, and how it is reflected on the safety and efficiency of the autonomous heating system.

The main functions of the automation

The main purpose of automation in heating systems is an instantaneous response to a change in the situation. One of the main tasks of automatic adjustment devices is the cessation of gas supply to the operating area. Situations in which it may be necessary to cut off the supply of household gas, may be the following:

the poor work of the exhaust device, the deterioration of the thrust, in which the likelihood of the harmful combustion products is high;
sharp discharge pressure in the main gas pipeline;
unauthorized flame damping on the main burner.

In the listed situations, it is thanks to the automation of a gas boiler that gas fuel supply is controlled, which ensures the safety of tenants. It is precisely for security reasons that, in accordance with the existing standards, automatic systems, it is necessary to equip all old models of gas-heating equipment, which did not provide for the equipment of these devices. As for the gas heating units of the last issues, it is boilers with automation.

For reference: In some cases, it is cheaper to install a new boiler than to engage in the modernization of the old heating system, equipping the automatic boiler. The reason lies in the essential structural differences of the models of the old sample from modern heating units.

What automation is better - mechanical or electronic?

Instruments controlling the operation of heating equipment can be mechanical or electronic. In budget models of gas boilers, in most cases, a variant of mechanical, manual control is used. Despite the fact that the level of technical progress reached unprecedented heights, the mechanics remains a reliable and proven tool. Automatic safety of gas boilers, acting in manual control mode, is an order of magnitude cheaper. The principle of operation of most models with manual control boilers is simple and understood for domestic use.

The regulator of the intensity of the coolant in the radiator of the water heating system

The automation unit of the mechanical principle of action is easier to maintain and repair. The disassembly of such an aggregate is quite able to a specialist - heat engineering, which provides a prophylactic inspection of boiler equipment in your home.

Manual, mechanical control of the gas boiler is independent of the power supply - the owner of the housing independently sets the temperature desired to heat the living room, everything else depends on the laws of physics, which are based on the work of the mechanism.

For reference: the heat exchanger is equipped with a thermocouple - a mechanism based on a plate combined from two parts - steel and nickel. In the process of heating, the plate is lengthened, and when cooled, it decreases in length, affecting the valve that opens or closes the supply of gas into the working area. Based on the same principle, the thrust regulator is also equipped with gas boilers with an open combustion chamber. The bimetallic plate with an increase in temperature to a critical mark (more than 750c) is strung out, the erosion chain. With a decrease in the flame, the plate is returned to the natural position. Everything is simple and understandable.

Another principle of operation is laid in automation with electronic filling using not the physical properties of materials and environments, but a fundamentally different way to transmit signal equipment.

Electronic Automatic Control Systems

The most common type of automation, which is used in the budget models of boilers - electronic thermostat.

The device is installed indoors and controls heating based on the external thermal sensor signals located in the current area of \u200b\u200bthe room. When the temperature is reduced below the installed limit to the boiler, an inclusion signal is applied. When the optimal temperature parameters is reached, the sensors transmit a shutdown signal to the system. Room thermostats have a cable connection with gas boilers.

In this case, the presence of a thermostat provides an optimal heating temperature of the gas boiler and the cost of blue fuel consumption. To date, thermostats of several types are available on sale, featuring functionality, technical characteristics and installation method. Programmable devices provide maintaining an optimal temperature mode within a predetermined period of time.

Note: Some models can automatically control the operation of the gas boiler during the day, other samples of equipment are able to control the working unit during the week. Automatic wireless control devices are also manufactured, allowing remotely control the boiler operation. The radius of the action of modern remote control systems, depending on the selected model, is 25-100 m.

Conclusion

What is better, mechanical automation or electronic control devices solves the consumer. A good gas boiler can work successfully both when manually controlled and using electronic automatic devices.

Modern devices that are equipped with all the currently existing models of gas boilers are an integral part of the heating system. Without configured, no gas boiler will not work correctly.

Currently, many manufacturers went further, because the requirements for the convenience of gas boilers are all rising. Therefore, modern electronic automation can additionally:

Control and manage the work of the pump.
Protect the heating system from freezing. In this case, the automation can quickly launch the heating boiler if a sharp decrease in the temperature indoors has occurred.
Protect the heating system against the failure of the three-way valve.
To conduct independently diagnosing heating and identify malfunctions of elements and parts.

Non-volatile

First, it is the cheapest designs.
Secondly, they have a manual setting, which makes it possible to understand the regulation processes of even the most distant people from these instruments.
Thirdly, this is the autonomy of the blocks, because for their work there is no need to connect to electrical networks. Even if for some time the electricity will be disabled, the boiler will simply adjust.

Currently, the manufacturers of gas boilers to the mechanical automation unit are added two sensors:

Sensor thrust.
Flame sensor.
