COUNTERFLOW THREE-FUEL SWIRL BURNER Russian patent published in 2023 - IPC F23D1/02 F23D17/00 

FIELD: power engineering.

SUBSTANCE: countercurrent three-fuel vortex burner comprises a cylindrical vortex chamber, a confuser-diffuser vortex chamber, a combustion chamber, a flow-swirling nozzle inlet device located between the cylindrical vortex chamber and the combustion products outlet pipe, a casing of the cooling channel made coaxially with the cylindrical vortex chamber, a compressed air supply pipe, made tangentially to the casing of the cooling channel, the liquid or gaseous fuel supply pipe, placed coaxially with the cylindrical vortex chamber, the confuser-diffuser vortex chamber and the combustion chamber, the igniter. The burner is equipped with a dust-air mixture supply pipe installed tangentially to the cylindrical surface of the combustion chamber.

EFFECT: reduced probability of flow blockage in the flow part of the nozzle inlet device swirling the flow, increased the efficiency of convective cooling of thermally loaded elements.
