VORTEX AFTERBURNING BOILER Russian patent published in 2021 - IPC F23B10/02 

FIELD: energy industry.

SUBSTANCE: vortex afterburning boiler contains vortex afterburning chambers formed by furnace screens and walls with a horizontal axis of rotation, tangential and exhaust nozzles of the afterburning blast, connected through exhaust windows in which the exhaust nozzles of the afterburning blast are installed, with convective flues, and the furnace chamber, which has a layered furnace with fuel supply, furnace blast and ash discharge systems. Vortex afterburning chambers of the radial type are used, the furnace chamber is located below them, communicating with them through a lifting flue, inlet nozzles installed in their upper part, tangentially to their horizontal axis, and bunkers located in their lower part with entrainment return channels and control valves. The bunker in the lower part of the vortex afterburning chamber is isolated by a non-gas-tight screen covering it.

EFFECT: creation of economical boilers, having increased environmental and operational indicators, which are universal in terms of the types of solid fuels and waste burned.
