HEAT RECOVERY BOILER Russian patent published in 2013 - IPC F23G7/06 F22B1/18 F23J15/00 C10J3/86 

FIELD: power engineering.

SUBSTANCE: heat recovery boiler is characterised by availability to a reactor, to the lower part of which two burners adjoin, and to the side surface of the reactor a horizontal flue adjoins for supply of smoke gases, at the same time smoke gases, which are discharged from the horizontal flue of smoke gases supply, arrive into the zone of active combustion of the reactor, which is arranged in its lower part, a system of heat recovery for smoke gases, which arrive into the reactor of the heat recovery boiler, a nozzle of smoke gases discharge from the reactor, which comprises an additional system of smoke gases heat recovery and at least one smoke exhaust. The heat recovery boiler is also characterised by the fact that it additionally comprises a distributor of smoke gases flow, which arrive from the horizontal flue into the reactor of the heat recovery boiler, at the same time the specified distributor is arranged in the specified zone of active combustion oppositely to the zone of adjacency of the specified horizontal flue to the reactor, as a result of which two mutually crossing vortex flows are generated in the reactor, a circular header, which adjoins the horizontal flue of smoke gases supply and comprises additional nozzles for supply of smoke gases into the reactor, which adjoining to the side surface of the reactor so that smoke gases arrive from the circular header into the zone of active combustion of the reactor along with the movement of both specified vortex flows.

EFFECT: heat recovery boiler is compact and simple to make and at the same time efficient to decontaminate smoke gases.
