A fluidized bed combustion system and method in which a plurality of enclosures, each having a furnace section and integral recycle section are joined using common walls. Openings are provided in lower portions of the common walls for permitting the fluidized bed material to flow between adjacent or opposing furnace sections and between adjacent recycle sections. Openings are also provided in upper portions of the common walls for equalizing the gas pressure between the adjacent or opposing furnace sections.
