FIELD: technological processes.
SUBSTANCE: invention relates to a device and a method for additional treatment of at least gases after a gasification process in a fluidised bed, in particular after a high-temperature Winkler gas generator. Device for additional treatment of at least gases after gasification process in fluidized bed, in particular after a high-temperature Winkler gas generator (HTW gas generator) of a gasification process in a fluidized bed under pressure, comprises a solid particles separation unit, which can be located after gasification process in fluidized bed and before gas cooler and which can be used for additional treatment of gases; wherein the additional treatment device comprises an intermediate cooling unit, which can be located after the gasification process in the fluidised bed and before the solid particles separation unit, comprising a steam gasification return line, which is configured to be connected to a gasification process in a fluidised bed, note here that solid particles separation unit is composed of cyclone cartridge filter.
EFFECT: possibility to use maximum possible range of working pressures.
