GAS GENERATOR FOR MOIST FUEL GASIFICATION Russian patent published in 2012 - IPC F23G5/27 

FIELD: power engineering.

SUBSTANCE: gas generator for moist fuel gasification comprises a rectangular hopper consisting of two parts: an upper one for fuel drying and a lower one for pyrolysis, a loading hatch, an air belt with tuyeres, a neck, an ashpit, a blow fan, and also a loading unit; a recuperative heat exchanger, an oxygen concentrator, additional heating elements, an air jacket, an auger for ash removal, the upper part of the hopper for drying fuel is communicated with the loading unit by an auger feeder, is isolated from the lower part of the hopper for pyrolysis with a blade drum feeder, comprises additional heating elements in the form of an air jacket and a cylindrical-conical element installed inside the hopper and communicating with the air jacket; the air jacket in the lower part of the gasifier communicates with the air belt via two diametrically arranged nozzles.

EFFECT: such arrangement of a gasifier makes it possible to produce gas with high calorific value.
