METHOD OF PRODUCING ELECTRICITY FROM UNCOMMEDIATE (WET) FUEL BIOMASS AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2017 - IPC F23G5/04 F23K1/04 F01K17/04 

FIELD: power industry.

SUBSTANCE: method provides electric power production by two-step process scheme of feedstock gasifying in gasification reactor of direct process-steam gasification in a dense layer, in particular cylindrical inclined rotating gasification reactor in the filtration combustion mode with direct heating and subsequent direct combustion of the resulting fuel gas and converting thermal energy produced steam into electricity by means of heat (steam) condensing machine and a power generator. The invention provides for the recovery of "waste" heat by condensing the exhaust steam in a closed circulation circuit of the working fluid (water/organic coolant) through a two-stage air cooling scheme with intermediate (interstage) convective air-to-air drying of the feedstock by forced circulation of atmospheric air. In the practice of the invention, it is proposed to use a two-stage air condenser and a drying apparatus, for example, a drum type, as well as various types of a thermal (steam) machine (steam turbine, steam screw machine, steam piston engine, and organic cycle turbine).

EFFECT: invention makes it possible to increase the electrical efficiency and expand the range of cheap low-grade raw materials used in terms of substandard, including moisture content, fuel biomass, including utilized substandard solid municipal waste, while minimizing the harmful impact on the environment and ensuring the autonomy of the power generation process.
