METHOD FOR PRODUCTION OF PYROLYSIS RESIN-FREE COMBUSTIBLE GAS DURING CONDENSED FUEL GASIFICATION AND GAS GENERATORS FOR METHOD REALISATION Russian patent published in 2014 - IPC C10J3/12 C10J3/66 

FIELD: oil and gas industry.

SUBSTANCE: group of inventions may be used in the field of condensed and solid fuel processing to generate power. The method for production of pyrolysis resin-free combustible gas during gasification of condensed fuel includes fuel delivery through a loading unit (1) installed in the upper part of the gas generator and loading of a solid incombustible material through a separate loading unit (4) which ensures material staying in the counter-flow of gaseous products. Oxygen-containing gas is delivered to the lower part of the gas generator, pyrolysis and fuel combustion in the gas counter-flow are made. Solid residue is unloaded from the lower part of the gas generator. Gaseous products from the upper part of the gas generator are outputted from a layer of the solid incombustible material not mixed with the fuel. Gaseous products form in result of pyrolysis and drying are separated from the fuel layer and fed to the combustible area (9) placed below the area where fuel and solid incombustible material are mixed (8). The used gas generators are represented by multiple-bedded furnaces, a shaft reactor, and a rotating drum.

EFFECT: group of inventions allows receipt of combustible gas free of pyrolysis resins at low temperature and high energy efficiency.
