GAS GENERATOR FOR PRESSURE GASIFICATION OF GRANULATED SOLID FUEL Russian patent published in 2013 - IPC C10J3/42 

FIELD: oil and gas industry.

SUBSTANCE: invention is related to equipment for gasification of granulated solid fuel and it can be used in power generation, gas production and chemistry industries for the purpose of synthetic gas and crude gas production. Gas generator (1) represents a closed reaction vessel containing fluidised bed (4) formed by fuel; feed gate (3) installed in the upper part for continuous fuel delivery under; top gate (17) installed under bell-shaped narrowing of the bottom (14) for ash unloading to ash disposal gate (16); revolving grate (11) built-in over bell-shaped narrowing of the bottom (14) with possibility of gasifying agent delivery from below to fluidised bed unloading of ash through bell-shaped narrowing and adjoining tubular section (15) to ash disposal gate. In the tubular section (15) there is a built-in slide gate (19).

EFFECT: invention allows continuous ash unloading without interruption of the process and negative impact on the process pressure and temperature and continuous running of the revolving grate.
