CYCLONE FURNACE EXTENSION Russian patent published in 2009 - IPC F23C5/32 F23C6/04 

FIELD: heating.

SUBSTANCE: invention refers to facilities for incineration of processed wood biomass; it can be implemented in industrial power engineering. The technical result is achieved in the cyclone furnace extension consisting of a cyclone chamber equipped with tangential nozzles of primary air and a branch for axial supply of fuel, of an after burning chamber for big fractions located under the cyclone chamber, and of a conic grate with supply of secondary air under it installed in a lower portion of the after burning chamber, on the side surface of which an outlet branch is assembled; also the after burning chamber and the cyclone chamber are divided between them with a throat with pass-through opening of a square cross section formed with four gates facilitating variation of the size of pass- through opening.

EFFECT: increased completeness of fuel combustion at simultaneously reduced creation of combustion oxides.
