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 and can be implemented in industrial heat and 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 with a branch for axial supply of fuel, and of an after burner chamber for big fractions assembled under the cyclone chamber and separated from the latter with a throat with collar, in the lower part of which there is installed a conic grate with supply of secondary air under it, while an outlet branch is installed on the side surface; also two tangential slots are arranged for supply of tertiary air on the side surface of the outlet branch.
