ABSTRACT:
The present invention relates to a method for obtaining combustion gases of high calorific value, wherein carbonaceous materials are allothermically gasified in a fluidized layer containing solid particles, using a gaseous gasifying agent and by supply of heat, and the gases thus produced are separated from the solid particles and withdrawn. Said method is characterized in that the solid particles are indirectly heated in a first descending bed and supplied to a second ascending fluidized bed in which the fluidized layer is formed and gasification takes place for the greatest part. The method further relates to an apparatus for performing said method.
