ABSTRACT:
A process for recycling coal fines and ash particles in the reaction effluent from a fluidized bed gasification reactor for further gasification is disclosed. Surfaces of the reactor exit pipeline, cyclone inlet pipeline and first stage cyclone are maintained at a temperature lower than that of the effluent through the use of cooling jackets, thereby preventing ash adhesion on the surfaces.
