In front of gas collection chamber (7) in gas combustion chamber (8) is vertically mounted burner (9), and above a burner (9) heat diffuser (12) with openings, for maintaining a constant temperature and even heat distribution for heat removal collectors (13).

Description

The invention relates to heating technology, namely to solid fuel boilers for burning firewood, wood waste, fuel pellets, grain and coal.

Known domestic solid fuel boiler with gas burner described in patent application no. 2010 037, published in the State Patent Bureau Official Bulletin, Inventions, Designs, Trademarks, 2011 No. 2. The boiler consists of a metal double-walled housing, a combustion chamber with a lid, a combustion chamber, a double-walled burner, horizontally mounted in the gas combustion chamber, air supply elements, a chimney for exhaust of combustion products and a heat exchanger.

v

The disadvantage of the known domestic solid fuel boiler is that the horizontally mounted burner does not prevent the burning fuel from falling on it, in addition, the gas burning zone is shorter and the upward spread of the heat is longer. As a result, the heating temperature is reduced and this does not ensure complete and high quality combustion of the fuel.

The object of the invention is to improve the boiler operating conditions, to ensure complete combustion of the fuel, irrespective of the power of the boiler, constant heating temperature and even distribution thereof to the heat recovery collectors.

In order to achieve the object of the invention, the burner is mounted vertically in the combustion chamber of the generator gas, and a metal heat dissipator with openings at a distance of not less than 150 mm is installed above it, maintaining a constant heating temperature and uniform distribution of heat output to the collectors. The diameter of the openings in the incandescent lamp shall be at least 10 mm.

The invention is illustrated by a schematic diagram of a gas generator solid fuel boiler (see figure).

Gas generator solid fuel boiler consisting of metal body 1 with double walls. Inside the boiler body 1, the loading chamber 2 is covered by a metal cover 3 from the top. The bottom chamber of the charging chamber 2 is equipped with a fire door 4 with a primary air supply valve 5 and a metal fire-resistant grill 6. The charging chamber 2 directly connected to the The inner part 1 has a separate gas burner chamber 8, the lower part of which has a vertically mounted burner 9 and an air supply tube 10. A second air volume is provided in front of the burner 9 from the gas collecting chamber 7 through a hole 11. The gas burner chamber 8 9 a heat sink 12 at least 150 mm apart, with openings of at least 10 mm in diameter, ensuring a constant heat temperature and an even distribution of the heat supplied to the collectors 13. Because the heat dissipator 12 is constantly hot, it also serves as a catalyst that affects the combustion process. The heat recovery collectors 13 are located in the rear part 1 of the boiler body. Between the charging chamber 2 and the top of the gas combustion chamber 8 there is provided a smoke exhaust valve 14. At the rear of the boiler body 1 there is provided: a cold water supply pipe 15 at the lowest level and a hot water outlet 16 at the highest level. designed to heat the chimney. Pipes 15 and 16 are connected to the heating system elements.

The gas generating solid fuel boiler operates as follows.

Prior to loading the fuel into the charge chamber 2, open the smoke exhaust valve 14 and the firing door 4 together with the primary air supply valve 5. In this way, the primary air flow into the charging chamber 2 ignites the fuel. The combustion of the solid fuel takes place over the grate 6. The combustion generates a flammable generator gas which collects in the gas collection chamber 7. It mixes with the secondary amount of air entering the gas collection chamber 7 through the opening 11 to form a flammable gas mixture. When heated, the flammable gas mixture enters the burner 9, which is also supplied with air by tube 10. The flammable gas mixture burns intensively at high temperatures of 900-1700 ° C. The burner flows vertically upwards and passes through the heat diffuser 12, which does not reach the boiler walls and distributes the heat supplied to the collectors 13 evenly.

The stated design of the boiler guarantees complete combustion of the fuel regardless of the boiler output, which results in the efficient production of combustible generator gas. The vertical position of the burner improves the operating conditions of the gas generator boiler, avoids the fall of burning fuel on the burner, allows the heat to rise abruptly without contacting the boiler walls, which does not change the heating temperature and result in better combustion of the generator gas mixture. In addition, a heat sink is fitted which, together with the catalytic converter function, maintains a constant heating temperature and evenly distributes the heat released to the exhaust manifolds.
