ABSTRACT:
A fluidized bed reactor has a pair of cyclone separators which receive flue gas with entrained solids and wherein the solids are separated from the flue gas in the separators for flow into a fluidized distribution conduit. The flow of separated particles is divided into two particle streams and fluidizing air is introduced into the duct. The fluidized separated particles are then conveyed to the combustion chamber of the reactor through an upright conduit in turn connected to a downwardly inclined conduit connecting the combustion chamber with the fluidized separated particles in the duct. The downwardly inclined conduits are substantially equidistantly distributed along the lateral extent of the combustion chamber to provide even distribution of the solid separated particles with fuel mixed therein in the combustion chamber.
