摘要： A circulating fluidized bed (CFB) boiler includes a reaction chamber, where a bubbling fluidized bed (BFB) is contained within an enclosure within the lower portion of the reaction chamber and contains an in-bed heat exchanger (IBHX) that occupies part of the reaction chamber floor. A plurality of in-bed secondary air nozzles comprise a plurality of tubes which are grouped together and run across the width of the BFB between the BFB enclosure wall and an outside wall of the CFB. The nozzles are positioned to prevent the deflection of solids falling onto the BFB from the CFB by the secondary air jets while avoiding a complicated structure that would interfere with gas and/or solids movement in the furnace. The nozzles' exit openings are flush, or almost flush, with the BFB enclosure wall.

摘要： In a fluidized bed thermal reaction apparatus for burning or gasifying combustibles containing noncombustible components, the accumulation of noncombustible components in a fluidized bed furnace (1) is prevented, and the noncombustible components are taken out smoothly, whereby the combustibles are burnt or gasified. The fluidized bed thermal reaction apparatus is provided with a mild diffusion plate (2), forcible diffusion plates (3) and auxiliary diffusion plates (3') which have a plurality of fluidizing gas supply holes (72, 74, 76) respectively, and noncombustible component recovery ports (8) formed between the auxiliary diffusion plate and forcible diffusion plate. A part of the fluidizing gas is supplied from the noncombustible component recovery ports, or the noncombustible component recovery ports are opened laterally, whereby a continuous fluidized bed circulating current (19) is formed at a furnace bottom. The mild diffusion plate and auxiliary diffusion plates have inclined surfaces extending downward toward the noncombustible component recovery ports, and the forcible diffusion plates inclined surfaces extending upward gradually as they are away from the noncombustible component recovery ports.
