FIELD: machine building.
SUBSTANCE: vortex burner for combustion of solid powdered fuel containing branch for initial air supply, combustion chamber, branch for secondary air supply, holes for secondary air supply, partition, additionally is has injector for fuel powder supply, electric heater, chamber for powdered fuel mixing with oxidant, and confusor-diffuser transition, at that holes for the secondary fuel supply are made at input to the cylindrical section of the combustion chamber, the head part of the combustion chamber together with injector of the fuel powder supply and section for powdered fuel mixing with oxidant is vortex injector of the straight-flow type, electric heater is made as cylindrical rod and is installed axisymmetric inside the injector of the fuel powder supply, the confusor-diffuser transition is made upstream the cylindrical part of the combustion chamber.
EFFECT: combustion chamber, increases quality of the fuel mixing with the oxidant, increases complete combustion of the solid fuel in the device.
