Gas generator boilers with own hands: blueprints

Gas generators can be manufactured by their own hands . Such equipment has become widely used today, because for its work it is possible to use different types of wood according to the type of pressed briquettes, waste and logs. The operating principle of the plants differs somewhat from conventional solid-fuel models. At first glance, the structure seems more complicated, but it has a lot of advantages, and also saves money that is spent on heating.

Gas generator system

In order to produce gas-fired boilers with their own hands, it is first necessary to familiarize themselves with the device and the principle of their operation. As the basis of such an installation is a furnace, which has two compartments. In the first of them, wood is combusted with insufficient oxygen, whereas in the second compartment the released gases burn out. These compartments are separated by a grate. If we talk about the differences of the pyrolysis boiler from the usual classical, then as the main one we can single out the movement of air downward. Significant aerodynamic resistance eliminates the possibility of free circulation of air masses. Therefore, the forced draft is arranged, which is provided by the fan-blower method (it is replaced in some cases by a smoke exhaust).

The main principle, which is incorporated in the operation of installations of this type, is the decomposition of wood under the influence of high temperatures. Subsequently, the fuel is divided into gaseous volatile mixtures and coal. The process takes place in the laying chamber at high temperature, but the air should not be enough for a full burning; Volatile mixtures that fall into the second chamber, burn out at a temperature of up to 1000 degrees. In the end, carbon monoxide is sent through the convective part into the chimney, giving away its heat. In order to provide ideal conditions for the burning of firewood, the inner surface must be covered with refractory lining. At the same time, both chambers should be faced.

Recommendations for the master

It is quite difficult to assemble the gas-generator boilers by their own hands, therefore it is recommended to use the Belyaev boiler as the basis. The master himself will be able to solve the problem of changing the design, this will depend on the engineering and professional skills, as well as the desire to experiment. Do not change the internal volume of space. Instead of the liquid coolant in the described equipment, hot air can be used to heat the house, which will circulate through the pipes. This option allows you to avoid frostbite, which is why such systems are widely used, because they can be installed in suburban homes. In winter, problems with the exploitation of such heating will not arise.

Preparation of materials for work

In order to produce gas-fired boilers with their own hands, it is necessary to prepare some materials and tools. It will take a Bulgarian with ruffs for stripping and cutting wheels, a welding machine, and consumables. Among the latter, one can distinguish pipes for cold and hot water supply lines, doors, as well as locks and fasteners for them. You will also need a blown fan, a temperature sensor, a metal of considerable thickness, fireclay brick and grate.

Features of gas generator set assembly

If you decide to perform the gas generator with your own hands, the drawings should be considered even before the work starts. At the first stage four walls are prepared, which are cut from sheet metal. In the front wall, you need to make two rectangular holes using the bulgaria. The lower one is intended for the ash pan, while the upper one is for the furnace. The rear wall can be put aside for a while. The remaining plates must be welded together, and at the junctions, gently grind the emergent growths, using for this all the same Bulgarian. After assembling the heat exchanger, water or any other heat transfer medium will circulate through it, as a rule, it is liquid. All constituent elements must be securely welded and cleaned, as a result, a structure that lacks joints and seams should be obtained.

Installation of the heat exchanger and work on the smoke exhauster

If you decide to assemble the gas generator boiler yourself, the device it will be important for you to know. The technology at the next stage involves the installation of a heat exchanger in the furnace itself. The pipes should be run with water, and working pressure is created, this will allow to determine the presence of defects that can be expressed in leaks. The furnace will be located from the bottom, and not from above, as in the factory models. It must be separated from the gasification area, which is mounted above the grate. The department for burning fuel must be coated with refractory bricks at the bottom, sides and top. It is also important to provide an air duct. The next step is to install doors that are as tightly as possible pressed against the walls. After the exhauster is mounted, it is necessary to install a temperature sensor that will monitor the heating status inside and the combustion process.

Final work

If you will be making a gas-burning furnace yourself, the scheme and the principle of operation must be considered. They are presented in the article above. At the final stage, it will only be necessary to cut out the openings for the smoke exhausters and the chimneys, only afterwards it will be possible to weld the rear wall and grind it. Now you can check the efficiency, for this you need to use a device that is already ready to work. If no carbon monoxide is seen at the outlet, then the equipment is considered completely serviceable, it can be operated.

Additional work in the manufacture of pyrolysis boiler

When we make a pyrolysis boiler with our own hands, the drawings can be prepared independently, but quite often such jobs are trusted by professionals. Separately, it is necessary to highlight certain features that a pyrolysis boiler must possess. From the outside, you need to install a valve that will monitor the flow of the coolant passing through the heat exchanger. In order to increase the heat transfer, the coolant pipe must be designed in such a way that it has a bend. It must be performed in the form of a coil. The holes for fuel filling must be made in a rectangular shape, the metal cover must be provided on the door, it will allow a more tight fit. Before you make a gas generator with your own hands, the principle of operation of such equipment must be studied. It provides for the presence of a limiter that will control the airflow entering the interior space.

Safety precautions

It is quite difficult to manufacture pyrolysis equipment on its own, it is not always justified to produce such works. The resulting model can be used for heating an oversized utility room, as well as an apartment building. In the latter case, experts recommend purchasing factory equipment. It is important to properly install the gas generator. The area of the vent in the room should be approximately 100 square centimeters. Equipment must be removed from the surface and other objects by a distance of 0.2 meters. Before the boiler it is necessary to lay a sheet metal, the thickness of which is 3 millimeters. This will eliminate the occurrence of a fire in the fallout of combustion products by the type of coal or ash during the operation of the equipment and the laying of fuel. The gas-fired oven can be made from handy tools with one's own hands. However, it is important to place such a device on a brick or concrete foundation. For pyrolysis installation you need a separate room. It can be a boiler room, which must be protected from fire as much as possible. The chimney should be well insulated with a heater so that soot and other layers do not form inside of the supercooling.

Conclusion

The design and layout of the gas-fired boiler on firewood, which are presented in this article, will help you in the independent manufacture of equipment. However, it is important to remember that professional masters do not advise using such installations as heating systems for an apartment house. This is not always justified and can cause a fire. That is why it is not recommended to save on the purchase of quality equipment.
