FUEL COMBUSTION Russian patent published in 2014 - IPC F23B101/00 F23B80/00 F23B10/00 F24B1/24 

FIELD: power engineering.

SUBSTANCE: fuel combustion consists in fuel feed to fire-box, fuel ignition, air feed to fire-box, afterburning of fuel with additional air feed with the help of heat energy accumulator and heat power takeoff. Note here that gases from combusted fuel flow via ascending labyrinth gas duct. Gases with particles not combusted completely in inclined part of said duct are forced by ceramic units of heat power accumulator and afterburnt. Note here that air feed fro afterburning is performed at approach of gas flow with particles not combusted completely to heat power accumulator. Note that gas flow with particles not combusted completely is forced via clearances along and between heat power accumulator ceramic units and surfaces of ledges made at housing rear wall and L-like ledge at the web.

EFFECT: efficiency increased by 7-10 percent, simplified boiler design, power savings.
