GAS-GENERATING BOILER Russian patent published in 2011 - IPC F24B1/183 F24H1/00 

FIELD: power industry.

SUBSTANCE: gas-generating boiler includes furnace chamber made in the form of closed cylindrical capacity, water jacket enclosing the furnace chamber, inlet and outlet connection pipes, for water circulation, ash pit, exhaust pipe, door for fuel charging to furnace chamber, and screen separating the supplied air flow above fuel surface. At that, screen is in movable state and touches the fuel surface, mechanism for mixing combustion gases with air. Furnace chamber is separated with sectors into gasification chamber and gas afterburner chamber. Fuel charging door, ash pit and screen rotating about furnace chamber axis are located in gasification chamber. Mechanism for mixing of combustion gases with air and exhaust pipe is located in gas afterburner chamber. Gas afterburner chamber is bell-type and designed so that mechanism for mixing combustion gases with air is located at the top, and exhaust pipe for outlet of exhaust gases is located at the bottom. Gasification chamber is separated from gas afterburner chamber with a partition. And the mixing mechanism consists of tubular header for distribution of air flow and hole made in partition for inlet of combustion gases to gas afterburner chamber. Air flow from tubular header is directed towards the hole.

EFFECT: providing complete burning of combustion gases and possibility of additional fuel charging at any combustion stage.
