Patent ID: 8568496

Claim:
A gas generator ( 1 ) for the pressure gasification of solid granular fuels under a pressure of 5 to 100 bar and by heating with a gasifying medium consisting of steam and O2 or steam and air to obtain combustible gaseous compounds for producing synthesis gas or H2-suitable raw gas, comprising a closed reaction vessel with a fluidized bed ( 4 ) formed of the fuels, with a feeding sluice ( 3 ) mounted at the top for continuously introducing the fuels and a closure ( 17 ) mounted below a funnel-shaped constriction ( 14 ) of the bottom for discharging the ash ( 13 ) formed into an ash sluice ( 16 ), with a revolving grate ( 11 ) mounted in the lower portion of the reaction vessel above the funnel-shaped constriction, through which the gasifying medium can be introduced from below into the fluidized bed and through which the ash formed can be discharged into the ash sluice via the funnel-shaped constriction and an adjoining tubular portion ( 15 ), characterized in that a bulk-material slide valve ( 19 ) is mounted in the tubular portion ( 15 ).
