摘要： A fluidized bed gasification combustion furnace in which a gasification furnace and a combustion furnace are integrated with each other, and unburned char generated in the gasification furnace is burnt in the combustion furnace to use the resulting combustion heat for a heat source for gasification. The fluidized bed gasification combustion furnace (1) comprises a gasification furnace (3) and a combustion furnace (4), which are partitioned from each other by a first partition (2). In the gasification furnace (3), a swirl of a fluid medium is formed by diffusers (32, 33) disposed on the furnace bed, and a part of a rising flow enters the combustion furnace (4). The combustion furnace (4) is divided by a second partition (5) into a main combustion chamber (6) and a heat recovery chamber (7). In the main combustion chamber (6), a swirl of the fluid medium is formed by diffusers (34, 35) disposed on the furnace bed, and a part of a rising flow enters the heat recovery chamber (7).

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.

摘要： This invention relates to a composite circulation fluidized bed boiler. A fluidized bed portion of the fluidized bed boiler is divided by a partition into a main combustion chamber and a heat recovery chamber, and at least two kinds of air chambers, i.e. an air chamber for providing a large fluidizing speed to a fluidization medium and an air chamber for providing a small fluidizing speed are provided. The combination of air having different fluidization speeds and jetted from these air chambers generates a swirling circulation flow in the fluidization medium inside the main combustion chamber and a circulation flow of the fluidization medium is generated between the main combustion chamber and the heat recovery chamber. Inside the heat recovery chamber, heat recovery of an exhaust gas is made at a free board portion or downstream of the free board portion in an internal circulation fluidized bed boiler for lowering the fluidization medium in the form of the fluidized bed, and after the temperature of the exhaust gas is lowered, the exhaust gas thus cooled is led into a cyclone and the char in a fine particle form collected by the cyclone is returned to the portion immediately above, or into, the lowering moving layer of the fluidization medium in the main combustion chamber and/or the heat recovery chamber. Since the char is returned immediately above or into the lowering moving layer of the fluidization medium, it does not immediately scatter to the free board portion. Accordingly, though it is the fine particles, it sediments and diffuses sufficiently into the fluidized bed so that NOx generated by the combustion of coal or the like inside the layer can be reduced.
