WATER-COAL FUEL COMBUSTION DEVICE Russian patent published in 2012 - IPC F23C1/10 F23C3/00 F23K1/02 F23C9/06 F23C7/00 F23L9/06 

FIELD: power industry.

SUBSTANCE: burning device for combustion of water-coal fuel includes lined combustion chamber of cylindrical shape with horizontal rotation axis and flat end walls near the symmetry axes of which gas bypass openings are arranged, and cooling chamber screened with steam-generating tubes and provided with convection tube bank inside it, which are interconnected to each other by means of gas bypass openings; at that, combustion chamber is installed inside cooling chamber; on front wall of combustion chamber there mounted are fuel atomisers performing both separate and combined supply of various types of fuel and primary oxidiser, and blast nozzles installed with tangent supply of oxidiser, and inside combustion chamber there installed is central refractory insert; in addition, in lower part of combustion chamber there installed is slot-type nozzle connected to the zone behind convection tube bank of cooling chamber by means of gas duct for forced gas pumping from that zone to combustion chamber with possibility of gas flow and velocity control at the nozzle outlet; besides, deviation angle of nozzle axis from tangent to generatrix of combustion chamber cylinder changes from 0 to 30 degrees, as well as gas duct is installed from cooling chamber from the zone behind convection tube bank to blast nozzle with possibility of gas flow control.

EFFECT: homothermal temperatures of the furnace volume.
