METHOD AND INSTALLATION FOR GASIFICATION OF POWDER-LIKE SOLID CARBON FUEL AND INTEGRATED POWER GENERATION METHOD Russian patent published in 1999 - IPC

FIELD: solid fuels. SUBSTANCE: method of gasifying powder-like solid carbon fuel with higher than 20% moisture content consists in feeding fuel into one or several drying chambers under pressure and avoiding addition of water to fuel, reducing moisture in fuel to the required level by passing hot gas product through each drying chamber. Partially cooled and wetted gas is separated from fuel, which is transferred into gasification chamber to produce hot gas (at least part of which is deviated into drying chambers). EFFECT: facilitated gasification of friable materials. 24 cl, 1 dwg, 1 tbl
