ABSTRACT:
A reactor in which a furnace section, a heat recovery section and a horizontal cyclone separator are formed in a vessel. A bed of solid particulate material including fuel is supported in the furnace section and air is introduced into the bed at a velocity sufficient to fluidize same and support the combustion or gasification of the fuel. A mixture of air, the gaseous products of combustion and the particles entrained by the air are directed to the vortex chamber of the cyclone separator through an inlet duct. The helical end of the vortex chamber forces the mixture to spirally circulate within the chamber, where the solid particles of the mixture are separated by centrifugal forces. A central tube extends partially within the vortex chamber and receives the cleaned gases from the low pressure center of the chamber. The portion of the tube behind the helical end of the vortex chamber opens directly into the heat recovery area for passing the clean gases thereto. A trough extends from the lower portion of the vortex chamber to the fuel bed for receiving the separated particles and returning them to the bed.
