FUEL COMBUSTION METHOD Russian patent published in 2015 - IPC F24B1/185 F24C1/00 

FIELD: power industry.

SUBSTANCE: method of burning of fuel in the top-hat furnaces with the fuel combustion chamber and the fire grate comprises the fuel loading, ignition and burning of at the expense of primary air supplied through ash box. The movement of gases in a top-hat is performed without the pipe draft, with a possibility of accumulation of hot gases in the top part of the top-hat. Note that into the top-hat, directly into the burning zone, the secondary air is supplied. Hot gases move up, giving thermal energy to the top-hat, and cold particles of ballast gases fall down through the top-hat zones with the decreased temperature. After heating of the combustion chamber in it, below the secondary air supply, the superheated water vapour is supplied to the heated carbon thus obtaining combustible gases.

EFFECT: improving efficiency factor of furnaces and heat generators.
