Solid fuel gas-fired boilers

When using gas-fired boilers for wood, solid fuel must meet certain requirements. First of all, we are talking about the presence of a large amount of light substances in the composition and the absence of high humidity (no more than 30%). For boilers with a similar mechanism of operation, the following fuel options are suitable:

  • wood or firewood, the dimensions of which allow them to be easily loaded into the device;
  • woodworking waste, shavings;
  • briquettes from pressed wood dust;
  • biofuel pellets;
  • coal or coke;
  • brown coal and so on.

Gas-generating boilers are one of the types of solid fuel, usually water-heating devices. The essence of his work is that the fuel and volatile substances in it burn out separately. In other words, solid fuel pyrolysis occurs, which is why boilers are also called pyrolysis boilers. Especially this heating equipment is effective when working on firewood, wood briquettes, borax and some coal fractions.

Unit device

The design of the gas generating boiler is a furnace with two chambers, which are separated by cast-iron grates. The first chamber is designed for pyrolysis of firewood, and the second - for burning the emitted gas. In some designs, the gas chambers are connected to cooking stoves. The main parts of such a device are:

  • nozzle;
  • fan;
  • controllers;
  • air channels;
  • water pipes;
  • chimney.

In this video, we will consider the principle of operation of gas-generating boilers:

In addition, to ensure the safe operation of boiler equipment, the design contains: safety valves, pressure sensors, air supply regulators. General control and adjustment of the operational process is carried out using an electronic control unit. Some models of boilers have a remote control.

Fuel selection rules

During the combustion of any solid fuel, carbon monoxide is released. From the experience of using gas generators, it has been proved that the release of this gas in especially large quantities occurs during the combustion of wood.

Hence the conclusion that it is best to heat this unit with firewood. In modern boilers, their ignition and further combustion process is fully automated. At the same time, certain requirements are imposed on such fuel.

The moisture content of the wood used should not exceed 20%, otherwise it will have to be dried beforehand. At the same time, it is worth choosing only the most solid types of wood: beech, oak, acacia. You can not use coal in those models where this option is not provided, since the unit may fail.

The principle of operation of the equipment

During combustion, solid fuel begins to release gas, which continues to support this process. Wood-fired gas-fired boilers are designed in such a way that they cannot burn quickly as in conventional stoves. This happens because carbon monoxide burns in a separate chamber. Thus, the whole process is divided into several stages:

  1. First, solid fuel undergoes a drying process in a special section of the gas generator boiler.
  2. Next, the firewood burns in the firebox at a temperature range of 200 to 850°C. Oxygen practically does not enter the furnace during this process.
  3. The released gas burns in a special chamber using burners.

As a result, the fuel is separated into two components: a solid fraction and a gaseous substance. The removal of these parts from the boiler takes place separately, and when the gas and carbon come into contact during combustion, the smoke is purified from harmful substances.

Popular Models

Currently, gas-fired boilers for wood and other solid fuels are widely represented on the market for space heating equipment. They differ from each other both constructively and in cost. Among them it is worth noting the following models:

  1. OPOP ECOMAX 30 - economical boilers from Czech manufacturers. The presence of an electronic unit allows you to control two circulation pumps, a thermostat and a fan. The performance factor of the unit reaches about 90%.
  2. Viadrus Hercules U32 - the body of this unit is made of cast iron. The operation of the boiler is carried out on wood, coal and does not depend on the availability of electricity. There is no fan in its design, air is supplied naturally.
  3. ATMOS DC is a steel wood fired boiler. Existence of the exhaust fan allows to collect ashes practically without dust. Some varieties of this model also have a fan forcing air.
  4. Bastion M-KST-15P is a non-volatile boiler from Russian manufacturers. It has a large capacity, which allows the coolant to circulate through the system due to inertia. In such a heating system, circulation pumps are not needed.

The following models are also considered popular and inexpensive: Divo-10, Bourgeois-K STANDARD-20, Wattek PYROTEK 36, etc.

Advantages and disadvantages of boilers

The main advantage of such units is the high efficiency of solid fuel combustion. Compared to simple wood-burning stoves, when using a gas generator, the efficiency is usually much higher.

Most of these installations are non-volatile devices and can be installed at facilities that are not supplied with electricity. Such units were previously successfully installed on cars. In addition, boilers that do not need electricity are much cheaper.

To operate this device, you can use any type of wood, even waste from its production. Another significant advantage of such heating is that the boiler is able to work for a long time from one portion of solid fuel.

This feature makes it easier to operate these units. But still, these devices have a number of disadvantages, based mainly on the mandatory presence of a person during their maintenance.

This is especially important when choosing such devices in comparison with gas units. Besides, the gas generator needs to be serviced periodically, clean from soot and soot, since decay products exist in them.



Despite the high cost, after the purchase, a gas-fired solid fuel boiler helps to save on heating by reducing fuel consumption by 15-20%. An additional advantage is the long operating time of the gas generator from one tab.

Gas boiler device

A modern solid fuel heating gas-generating boiler bears little resemblance to the first gas generators. As a result of design and engineering solutions, the internal structure and appearance have undergone significant changes. Only the operating principle used remains the same, which is as follows:
  • Wood, when burned, releases a small amount of carbon dioxide. This process is called gas generation or oxidation.
  • If you create the necessary conditions, the burning rate slows down, and the amount of CO increases.
  • Carbon dioxide, after mixing with air in the required proportions, forms a combustible-air mixture.
  • The gas-air mixture burns well, and at the same time releases additional thermal energy.
The design and arrangement of a solid fuel gas-fired heating boiler differs depending on the model and manufacturer. The following nodes are required:


Depending on the model, the combustion process is carried out in a completely autonomous mode or with a certain participation of a person. Classic wood-fired units are loaded manually. Air supply settings, ash removal and other functions are performed by a person.

Automatic boilers on, operate in a completely autonomous mode. The whole process, from air supply to combustion waste removal, is controlled by automation.

Specifications for gas generation

Gas generation or carbon dioxide emission, in the process of wood oxidation, can only begin under certain conditions:
  • Limited air access - in order for gas to begin to be released, it is necessary to restrict the flow of air, causing the wood to literally smolder.
  • High temperature - the wood chars, turning into carbon and mixing with oxygen, forms carbon dioxide. For the production of CO, it is required to maintain heating in the furnace above 600°C.
  • Humidity - raw wood, when heated, releases steam instead of carbon dioxide. For gas generation, it is required that the humidity does not exceed 20%.

Household gas-generating solid fuel heating boilers of domestic production are less whimsical to the quality of the wood used. In models with vertical loading and, it is allowed to use firewood with a moisture content of 30 to 42%.

Fuel consumption in gas generating boilers

Solid fuel boilers with gas generator combustion have several advantages that make their operation economical:
  • Combustion of fuel in gas-generating boilers is carried out more slowly, due to the lack of intensive air flow. When a tree smolders, less heat is released than when it is fully burned. The lack of thermal energy is compensated by the afterburning of the released carbon dioxide.
  • Fuel consumption, in comparison with classical boilers, is reduced by 15-20%. At the same time, the amount of heat released during combustion practically did not decrease.
  • The use of automation reduces fuel consumption by at least another 10%.
A solid fuel gas-generating boiler of long burning, designed for wood, working on coal, quickly fails. Therefore, gas generators should be heated exclusively with wood or its waste. An exception is made for models specially designed to work on coal.

Is it possible to make a gas generator out of a simple boiler

The principle of operation of a gas-generating solid fuel boiler implies the use of mandatory components in the design:
  • Furnaces and afterburners - in the device of gas generators, an enlarged combustion chamber is specially provided. Afterburning is carried out in a separate chamber made of fireclay bricks.
  • The coolant surrounds not only the furnace, but also a broken smoke channel located inside the boiler. The scheme of the heat exchanger is quite complicated. The coolant must surround not only the furnace, but also the smoke channels.
It is possible to make a gas generator from an existing wood-burning boiler, but at the same time, you will have to face the following difficulties:
  • Limitation in the size of the combustion chamber - to create the temperature necessary in the process of gas generation, it will take a full-fledged burning of firewood for half an hour. All fuel will burn out in approximately 1.5-2 hours, which negates the efficiency of the converted boiler.
  • The lack of free space will lead to an even greater reduction in the furnace, due to the installation of an afterburner.
After conversion, you should not expect the same performance indicators as for factory-produced gas generator models. It is much easier to make a gas generator again than to remake an already existing boiler.

Rules and conditions for installation and operation of the boiler

Gas-generating boilers on solid fuel of long burning, demanding on operating conditions. The efficiency of work is influenced by the characteristics of the boiler room, smoke exhaust and ventilation systems. The room used for the boiler room is subject to the rules of the PPB regarding the operation of solid fuel units. General installation recommendations are:
  • Installation of a boiler with a capacity of up to 40 kW is carried out anywhere in a residential building, subject to compliance with fire safety rules. A heat generator with a capacity of 40 kW or more is installed in a separate room.
  • The size of the room for the boiler is at least 8 m². The presence of supply and exhaust ventilation is mandatory.
  • The walls and floor of the boiler room are lined with non-combustible materials: ceramic tiles or cement-sand plaster.
  • The chimney is made with a minimum number of corners and a maximum length of the vertical section of not more than 1 m. When passing through floor slabs and roofs, fire breaks are provided.
As a recommended measure, smoke detectors are installed in the boiler room. If a connection to the mains is required, a switchboard with automatic machines is arranged outside the room where the solid fuel unit is located.

How to choose a gas generating boiler

When choosing a suitable model of gas generating equipment, several features related to the operation and functionality of the boiler, and its performance are taken into account:
  • Design features - the consumer is offered boilers using the principle of upper and lower combustion, with a vertical and horizontal firebox. From these characteristics depends on the operating time, the acceptable quality of the fuel used and other operating parameters.
  • Power - with an average thermal insulation of the building and a ceiling height of not more than 2.7 m, a formula is in effect that allows you to calculate the required boiler output: 1 kW = 10 m². An accurate calculation of the required power, taking into account all the features and technical characteristics of the building, is performed using special ones.
In addition to the listed criteria that affect the selection of heating equipment, additional attention is paid to the country of origin and the cost of the gas generator.

The best manufacturers of gas generating equipment

Literally 5-10 years ago, only 4-5 brands of gas-generating boilers, exclusively of European production, were presented on the heating equipment market. At the moment, the range of products has expanded so much that when choosing equipment, it has become impossible to do without qualified advice.

In addition to the European factories that have already proven themselves, domestic companies have established the production of gas-generating boilers. To facilitate the choice, all models can be divided into several groups on a territorial basis:

  • Russian gas-generating boilers - domestic companies manufacture products either independently (as in the case of BTS, Teplov, F.B.R.Zh., Phantom, Bastion, Gasgen), or with the support of foreign partners (Lavoro). Products are adapted to domestic conditions. Changes in the design made it possible to use fuel with a moisture content of up to 30-42%.
  • European boilers are traditionally considered the best in their class. Products are offered by Viadrus, Stropuva (practically the founder of gas-fired boilers), Atmos and others. Boilers of European concerns have a long service life, are distinguished by reliability, a high degree of automation and efficiency.

The cost of gas-generating boilers

European companies offer products of the Premium class, which affects both the comfort of control and operation, and the cost of heating gas generating units. So, the Latvian Stropuva can be purchased for about 100 thousand rubles. Czech Viadrus will cost between 180-200 thousand rubles, Atmos - 120 thousand rubles. and higher.

Domestic boilers can be found starting from 30 thousand rubles. For a high-quality gas generator, similar to European models, you will have to pay about 80 thousand rubles. (Prices are approximate based on 30 kW output).

Pros and cons of boilers with gas fuel generation

The experience of operating long-burning gas-fired boilers by domestic consumers made it possible to see the advantages and disadvantages of this type of equipment. There are several advantages to gas generators:
  • The duration of fuel burning in the gas-generating boiler is at least 6 hours. Some models, both domestic and European manufacturers, are able to work up to 3-5 days from one tab.
  • Greater heat dissipation compared to the classic model. The efficiency of gas generating boilers is 80-92%.
There are disadvantages:
  • Fuel restrictions. The heat exchanger of a gas-generating boiler that runs on wood, when switching to coal, burns out after a year of operation. It is impossible to heat with wet firewood and wood waste.
  • Cost - a classic boiler costs about 2-3 times cheaper.
Another disadvantage is the special rules for kindling and maintaining combustion during the operation of gas generating models. This disadvantage is temporary. After several fireboxes, the owner of the heating equipment gets used to the features.

Gas-generating boilers have no analogues among other models, regarding the duration of work from one bookmark, heat performance characteristics and other operating parameters. Somewhat limit the popularity of models - the high cost and features of operation.



Classic solid fuel boilers have two significant drawbacks: short operating time from one tab and low efficiency. To solve this problem, certain changes were made in the design and internal structure of the boilers.

As a result of improvements, gas-generating boilers for wood appeared. The principle of operation of a boiler with gas-fired combustion of firewood is based on the use of physical laws.

The principle of operation of a gas-fired wood-burning boiler

The operation of a wood-burning gas-fired boiler is both simple and effective. Any combustible solid, upon reaching a certain temperature, begins to release gas, through which, as a result, combustion is carried out.

In wood fired gas boilers, rapid combustion of the fuel is prevented by reducing the oxygen supply and removing CO to a separate afterburner.

Combustion, in the full sense of the word, is carried out only at the very beginning, when the fuel is ignited and the temperature necessary for gas generation is injected in the combustion chamber. After that, the air flow is sharply reduced, which causes the fuel to literally smolder.

Compared with a traditional boiler, a gas-fired wood-fired boiler has the following differences:

  • The device of the boiler furnace - for rapid heating to a temperature of 600 ° C, increase the thermal insulation of the combustion chamber. The design contains two fireboxes at once. One is for burning wood, the second is for afterburning CO.
  • Improved draft regulator - in order to prevent rapid burning of firewood, it is required to reduce the supply of oxygen to the furnace after the temperature reaches 600 ° C.

The moisture content of firewood for burning in a gas-generating boiler should not exceed 20%. The problem is that when fuel with a high moisture ratio is heated, a drying process occurs. Accordingly, gas generation does not start.

Some domestic models, in this regard, use the design of the boiler with a vertical laying of firewood and the principle of lower combustion. Such a boiler works on wood even with high humidity. Due to the high combustion temperature, the firewood located at the top of the chamber gradually dries out.

Depending on the design of the boiler, firewood burns for 6-12 hours. Some manufacturers offer heat generators with the ability to work from one tab for several days. But, as a rule, such models are much more expensive, which limits their popularity.

How and with what it is necessary to heat a wood-burning boiler of a gas-generating type

Any solid fuel emits a certain amount of CO during the gas generation process. It has been experimentally proven that wood produces the most gas during the oxidation process. Therefore, a gas-generating boiler for heating a house is optimally fired with wood. There are several requirements for the fuel used.

The greatest difficulty for most consumers is the correct combustion of the boiler. Unit manufacturers recommend the following sequence of actions:

  • When the air damper is open, firewood is ignited with a splinter.
  • In the normal combustion mode, the fuel continues to burn until the temperature in the combustion chamber reaches the values ​​sufficient to start gas generation.
  • The damper is switched to the mode of limited oxygen supply.
In modern models of heat generators, the combustion process is fully automated. Electric ignition of the fuel is carried out, automation controls the flow of oxygen into the furnace and the removal of combustion products.

What kind of firewood is best for a gas boiler

In normal combustion mode, wood-burning gas-fired heating boilers consume fuel, even more than classic models. Savings are achieved after switching to the gas generation mode. The energy efficiency of a boiler is directly related to the quality of the fuel used.

Wood requirements are as follows:

  • Humidity is not more than 20%.
  • It is best to use solid woods for the firebox. Suitable - beech, oak, acacia.
  • It is forbidden to heat the boiler with coal, woodworking waste, dust, as this leads to a decrease in the service life. This prohibition also applies to softwood.

Heating costs are reduced by burning quality wood. During the combustion process, more thermal energy is released, which increases the efficiency, energy efficiency and battery life of the boiler from one tab. Firewood consumption is reduced by approximately 30%.

Permissible wood moisture

On frankly raw wood, the boiler will not work. More precisely, the process of normal combustion will go on, but it will not work to switch to the gas generation mode. Wet fuel, if fresh air is limited, will simply go out.

The parameters of the moisture ratio in the wood are completely dependent on the design of the heat generator:

  • Side-loading boilers are the most common solution in European models of gas generating equipment that is demanding on fuel quality. The maximum permissible humidity is not more than 20%.
  • Top loading models - the design was first invented by domestic developers. The principle of operation of such boilers is the gradual burning of firewood laid in a vertical combustion chamber. Firewood, under its own weight, as the lower layer burns out, gradually sinks down. Warm air dries out the top fuel.
    Boilers with top loading are able to switch to the gas generation mode even with a relative humidity of firewood up to 45 ° C. At the same time, it is required that at least a third of the pledged fuel be dry.

The energy efficiency of the boiler depends on the quality of the fuel. With natural drying, 20% humidity is achieved after a year of drying firewood.

Choosing a gas-fired heating wood-burning boiler

The right choice of a gas-fired wood-burning boiler, due to the large range of products offered, can be quite difficult. Various nuances are taken into account: power, operating time from one tab, the presence of additional functions and automation of the combustion process.

It will not be superfluous to pay attention to the presence in the design of a backup heat source, in the form of an electric heater.

Two-circuit units are suitable for heating and hot water. In some models, there is no DHW circuit. Then, they are additionally purchased and connected to the indirect heating structure, which requires additional costs. All this is taken into account even before purchasing the boiler model you like.

Calculations are made according to the formula 1 kW = 10 m². This ratio takes into account the parameters of a building with an average amount of heat loss and a ceiling height of no more than 2.7 m. Additionally, the following aspects are taken into account:
  • The presence of a hot water circuit - a wood-fired gas-fired heating boiler for 10 kW, suitable for a house of 100 m². But, if it is planned to additionally heat hot water, 10-20% is added to the result. Accordingly, a heat generator with a capacity of at least 12 kW is required.
  • Additional heat loss - in self-calculations, the lack of good thermal insulation of the building, the presence of a large number of doorways and windows are often overlooked. All this affects the heat costs.
Accurate calculations are performed using online, taking into account all sorts of nuances: the quality of home insulation, the number of window and door openings, the location of the heated building, etc.

Selection by country manufacturer

The best gas-fired wood-fired boilers are made by German and Czech companies. Despite the high cost, the same Buderus or Viessmann remain one of the most popular units.

Domestic boilers Bastion, ZOTA, Topol M are significantly inferior in terms of their thermal performance and service life to Western counterparts.

The cost of a German-made gas-fired wood-burning heating boiler, per 20 kW, will cost approximately 100-120 thousand rubles. Domestic analogue of approximately 40 thousand rubles.

Pros and cons of boilers with gas-fired combustion of wood

The main advantage of gas generating equipment is the ability to connect to an existing water heating system. Installation work does not require serious material costs. After connection, savings of about 30% are achieved in reducing fuel consumption.

In the design of European units, new technologies are widely used that increase the comfort of operation, make kindling and combustion control as convenient as possible.

The disadvantages are the high cost of products (especially German and Czech boilers), as well as high requirements for fuel quality. The operating experience of a domestic consumer shows that the use of gas-generating equipment in the conditions of Russian realities is not only a possible, but also an economically viable solution.

Solid fuel boilers are a very relevant topic today, especially in areas far from electricity and gas pipelines. The variety of boilers differs only from the fuel used and the combustion technology. Solid fuel gas-fired boilers are those boilers that use a rather innovative principle of solid fuel combustion - pyrolysis. How does such a device differ from similar ones that work on the principle of combustion of wood, coal and other types of solid fuels?

Rice. one

Principle of operation

The solid fuel gas-generating boiler differs from the rest in the principle of combustion. Most likely, this cannot even be called combustion - it is pyrolysis or smoldering.

By design, the boiler has two combustion chambers:

  • In the first, the pyrolysis process occurs, that is, the smoldering of coal with a small amount of incoming oxygen. The result is a slow decomposition of solid fuel into tar, steam, oils and carbon - pyrolysis. This releases combustible gas.
  • In the second, the gas begins to burn intensively, with the flow of oxygen from the air and give additional heating, increasing the efficiency.

It turns out that in a solid fuel gas generator boiler, two types of fuel are used in parallel at once. Actually, solid fuel, which smolders, releases heat and combustible gas released during the pyrolysis process. This type of solid fuel gas generating boilers combines gas and solid fuel boilers.

Fuel

For the correct operation of a solid fuel gas-generating boiler, fuel is required that meets certain characteristics. It is necessary that it contain a large amount of light substances, not be too wet (no more than 20-30%), and water vapor should not interfere with smoldering.

The fuels listed below are suitable for pyrolysis boilers:

  • Wood or simply firewood the size of which is suitable for loading into the machine.
  • Shavings, woodworking industry waste.
  • Specially compressed biofuel briquettes - pellets.
  • Compressed wood dust - fuel briquettes.
  • The products of coal production are coke and hard coal.
  • Brown coal is also good for use.

As you can see, the variety of solid fuels for solid fuel gas-generating boilers is large. This makes their use widely available in many areas of residence.

Advantages

In addition to the variety of applications for different types of fuel, the geography of the use of gas-fired solid fuel boilers is also wide.

Among other advantages:

  • Autonomy, independence from any pipelines with gas or power lines.
  • There is an automation that supports the pyrolysis process by opening and closing the shutters, depending on the temperature (there is a thermostatic sensor).
  • It is possible to regulate the degree of heating of a solid fuel gas generator boiler by means of draft control.
  • Soot does not form on the walls of the apparatus.
  • Less emission of harmful substances into the atmosphere during pyrolysis.
  • The low cost of coal or firewood compared to electricity and gas.
  • Overheating protection - the presence of a protective cooling circuit.
  • Profitability at an efficiency of 85%.

Taking into account the listed significant advantages, we can say that the purchase of solid fuel gas-generating boilers is a good purchase. But there is no technology completely without some shortcomings, and a solid fuel gas-generating boiler is not without them.

disadvantages

  • The main disadvantage can be considered the high cost of a solid fuel gas-generating boiler, but you need to remember that operation and maintenance are cheap, and you will buy a boiler for many years.
  • Increased requirements for quality and, especially, for fuel moisture.
  • To remove burnt substances after pyrolysis, smoke removal is required. This means that the use of solid fuel gas-generating boilers is possible only in houses where it is possible to bring the pipe into the atmosphere, while not causing inconvenience to neighbors. Therefore, in high-rise buildings, it is hardly applicable.
  • Some temperature limitation. To prevent condensation, the temperature of the water coming from the heating system should be about 60 degrees.
  • It is impossible to automate the supply of solid fuel to the furnace.
  • High requirements for tightness of solid fuel gas-generating boilers. Leakage of flammable gas may result in an explosion or fire.

However, some disadvantages of boilers operating on the principle of pyrolysis are also inherent in some boilers that use coal, gas or wood as fuel. The ratio of advantages - disadvantages speaks in favor of solid fuel gas-generating boilers.

Design

The gas generating pyrolysis boiler has two combustion chambers. The first serves as a gas generator, where smoldering wood or coal emits combustible CO gas. In the second, gas is burned. It uses energy from both cameras. Since gas combustion is easier to control, automatic dampers are used to regulate the flow of gas after pyrolysis and oxygen from the air. This makes it possible to regulate the temperature of combustion and the return of energy to the coolant over a wide range.

When modernizing modern solid fuel gas-generating boilers, all the errors of early similar devices were taken into account. There are models that work completely independently. For example, the removal of harmful substances remaining after pyrolysis can occur without electricity. A safety water circuit has been created to prevent overheating of the boiler. Thanks to modernizations, the efficiency of the pyrolysis boiler is high. It is enough to load the first chamber with solid fuel once a day.

Mounting

Special requirements for the installation of a solid fuel gas-generating boiler:

  • It must be installed by professionals licensed to install this equipment. This is due to the specifics of pyrolysis boilers, where certain safety rules must be taken into account.
  • The pyrolysis boiler must be installed in a separate room (for example, on the basement floor). The room where the solid fuel gas generating boiler will be installed must be lined with refractory bricks.
  • It is not allowed to store solid fuels, combustible materials indoors or near the pyrolysis boiler.
  • The equipment is mounted on a concrete foundation and must stand firmly on it.

By entrusting the installation of the boiler to specialists, you will be sure of the correct and efficient operation of the equipment for many years to come. Do not risk and neglect the safety of your home.

Story

When developing solid fuel gas-generating boilers, first of all, attention was paid to the volume of combustion chambers and the amount of solid fuel consumed. But because of this, they achieved a slight increase in the efficiency with increasing overall dimensions and weight of the boilers. No one took into account that during pyrolysis a gas is released that was not effectively used in the chambers of previous models of boilers for wood or coal.

As a result of lengthy experiments, it became clear that it was necessary to use the properties of organic substances, which, with a lack of oxygen, emit combustible gas - pyrolysis. The use of solid fuel not for the main heat release, but for the production of CO made it possible to make a boiler that combines the combustion of solid fuel and gas. The solid fuel gas generating boiler increased the effect of heating, combined savings and low cost of fuel, using the pyrolysis process.

Outcome

By purchasing a solid fuel gas generating boiler, you get a highly economical heater capable of regulating the temperature of the heat carrier (heating water) over a wide range. Economy is essential. It is enough to load firewood or coal once a day. This frees you from the obligation to monitor the fuel level around the clock.

The use of automation will save you from manual control of the dampers. If gas supply will cost you too much or it is not available at all, then this is the best way to provide heating for a private house using cheap coal or firewood.
