Gas generator for gasifying solid granular fuels by applying pressure

Abstract

In a gas generator for gasifying solid granular fuels to obtain combustible gaseous compounds for producing synthesis gas or H-suitable raw gas, a fluidized bed formed of the fuels moves through a closed reaction vessel with a sluice mounted at the top for continuously introducing the fuels and with a closure mounted below the funnel-shaped constriction of the bottom for discharging the ash formed into an ash sluice, wherein above the funnel-shaped constriction of the bottom a revolving grate is arranged, 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. To achieve a continuous operation of the revolving grate, a bulk-material slide valve is mounted in the tubular portion.
