ABSTRACT:
A fluidized bed reactor system, including a reactor chamber defined by a wall structure formed by a plurality of tubes through which a heat transfer medium circulates, is constructed so as to provide numerous advantages over conventional constructions. A fast fluidized bed of solid material is established in the reactor chamber. A solid material processing chamber is disposed adjacent the reactor chamber on the outer side of a wall structure defining the reactor chamber, e.g. for recovering heat from the solid material. The processing chamber shares a common wall portion with the reactor chamber and a slow fluidized bed of solid material is provided in the processing chamber. Particle passage openings are provided in the common wall. Particles from the processing chamber are recirculated to the reactor chamber after treatment (typically cooling). A robust common wall structure is provided between the processing chamber and the reactor chamber, which has adequate open area for circulation of particles into the processing chamber, yet can substantially solely support the processing chamber.
