Abstract (en)
[origin: US4683840A] Boiler with a circulating fluidized bed, comprising a fluidization column completely lined with refractory material, a recirculation cyclone (2) and a duct (3) for recycling the solid materials. At least one heat-exchanger component (25, 26, 27) is placed in the recirculation cyclone (2). Pipe lines (30) enable air to be injected in tangential directions into the upper part of the cyclone (2) and thereby to increase the vortex effect. The combustion takes place substantially in the upper part of the cyclone (2). The fluidization column (1) comprises a widened section (1a) in its lower part.
