SOLID-FUEL BOILER WITH VORTEX FURNACE Russian patent published in 2016 - IPC F23B30/00 

FIELD: energy.

SUBSTANCE: invention relates to industrial power engineering, particularly, to solid-fuel boilers, universal by types of burnt fuel and wastes. In combustion chamber of solid fuel boiler with vortex furnace nozzles of secondary blowing by tangential pattern vortex is formed above burning fuel layer with horizontal axis passing through gas discharge openings, one or two symmetrically located on side walls. Released from layer volatile and ash are burn in vortex, and vortex in its turn, supports and activates burning layer on top, burns and discards due to centrifugal forces fly particles into layer and thus provides spark ignition of fuel in layer.

EFFECT: in end, deep burning of combustible of layer, ash and volatile.
