ABSTRACT:
A shaft furnace is provided for gasifying granular fuels in a fluidized bed. Such a furnace comprises a gasification zone containing the fluidized fuel bed and an overlying gas cooling zone having surfaces cooled by the tube surfaces of a radiation tube boiler. By providing such a gas cooling zone with a cross-sectional area substantially greater than that of the gasification zone, the gas effluent is cooled in such a manner that residues entrained in the effluent do not sinter onto the surfaces of the equipment in the subsequent path of the effluent.
