CIRCULATING FLUIDIZED BED REACTOR UTILIZING INTEGRAL CURVED ARM SEPARATORS A reactor having a furnace and a heat recovery section. The upper portion of said furnace extends coaxially in a spaced relationship within a shell. A bed of solid particulate material including fuel is supported in the furnace 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 particulate material entrained by the air and the gaseous products of combustion are discharged through a plurality of slots and arcuate arms disposed at the upper portion of the furnace onto the inner wall of the coaxial shell, effecting a separation of the particulate material from the mixture. The remaining mixture of air and the gaseous products of combustion rise upwardly and are directed to the heat recovery section. The separated particulate material is directed from the coaxial shell to a plurality of recycle conduits. The plurality of recycle conduits are connected to the lower portion of the furnace section for returning the separated particulate material to the bed. |
