WATER HEATING SOLID FUEL BOILER, WITH FRONT-END FURNACE OF COMBUSTION GASES AFTERBURNING Russian patent published in 2015 - IPC F24H1/00 

FIELD: heating.

SUBSTANCE: invention relates to the equipment for water heating by combustion of the solid fuel, such as coal, splitwood, pellets, sawdust, chips, and can be used in heat-power engineering. The solid fuel boiler contains casing, water-jacket made in the casing cavity, door set, fuel silo located in the casing, above combustion chamber, gear for air supply to combustion chamber and afterburning chamber, hole connecting the combustion chamber and afterburning chamber, ash chamber above the combustion chamber. Gear for air supply to the afterburning chamber is made out of through hole connecting the afterburning chamber and ash chamber, and gates regulating air flow supplied from outside.

EFFECT: simplified design is achieved in that hole and afterburning chamber of combustion gases is made under bottom wall of the door set aperture, and after side walls of the door set aperture channels are installed for waste gases release from the afterburning chamber.
