摘要： A method and apparatus for recovering heat from solid particles in a fluidized bed reactor, utilize a heat transfer chamber, having heat transfer surfaces disposed therein. Hot solid particles are continuously fed into the heat transfer chamber and gas is introduced into and discharged from the heat transfer chamber. Gas is introduced into the heat transfer chamber for controlling the flow of solid particles therein. The heat transfer chamber is divided into at least one heat transfer zone and at least one solid particle transport zone, by providing more heat transfer surfaces in the heat transfer zones (e.g. 90% or more of the total heat transfer area) than in the solid particle transport zones. The heat transfer is controlled by introducing separately controlled flows of gas into the heat transfer zones and the solid particle transport zones.

摘要： A centrifugal separator has a plurality of substantially planar walls, including a first wall, defining a vortex chamber having an interior gas volume and for establishing at least one gas vortex in the gas volume, and the gas volume has a cross section that is distinctly non-circular, (and preferably quadrate). In addition to conventional outlets the separator includes a gas inlet having at least one elongated jet-defining wall with a free end portion extending into the gas volume a first distance from the first wall, to define a gas jet that extends substantially tangentially to the gas vortex in the gas volume. An insert extends between the jet-defining wall free end portion and the first wall and defines a gas flow direction changing surface. The insert may be substantially solid refractory material, or include a number of cooling fluids circulating tubes, and a gas flow direction changing surface may be substantially planar or curved. The first distance is typically at least 50 mm, but less than 25% of the dimension of the wall perpendicular to the first wall. The jet defining wall and the gas direction changing surface may make an angle .alpha. between 20.degree.-80.degree. and the first distance may be between 0.2-5 times the width of the gas inlet. The height of the gas inlet is at least twice as great as its width.

摘要： A fluidized bed assembly, such as an ash cooler, includes first and second fluidized bed chambers each having a bottom portion and side walls. Fluidizing gas is introduced into the bottom portions to fluidize particulates within the chambers. A flow equalizer (such as a barrier having a number of openings associated with it) separates the chambers and provides a substantial uniform flow of particulates from the first chamber to the second chamber so that no dead spots or corners form in the chambers adjacent the flow equalizer. Heat exchanger components are typically provided in the barrier for circulating heat exchange fluid through the barrier. Also, heat exchangers are provided in one or both of the chambers to cool the particulates. The particulates mix in the second chamber, and after cooling may be recirculated to a gasifier/combustor for supplying ash to the first chamber. A classifier chamber is connected between the reactor and the first chamber. Fluidizing gas may be returned from the chambers to the reactor.

摘要： Method and apparatus for providing a gas seal in a CFB reactor, which is provided with a vertical, slot-shaped return duct (16), and for regulating the flow of circulating mass therein. The gas seal (22) is formed by arranging barrier means (22, 24, 26) on two different levels in the regulation zone of the return duct to slow down the flow of the circulating mass through the regulation zone. The flow of the circulating mass through the regulation zone is regulated by injecting fluidizing gas (56, 58, 60) into the regulation zone.

摘要： A method and apparatus for treating hot process gases produced in high temperature processes in a circulating fluidized bed reactor. The reactor (10) includes a mixing chamber (12), a particle separator (16) and a return duct (18) for returning the circulating mass from the particle separator to the mixing chamber. The return opening (24) of the return duct is so arranged that the flow of solids entering the mixing chamber via the opening is directed substantially downwardly. The inlet (22) for hot process gas is so arranged as to allow the hot process gas to flow into the mixing chamber as a substantially upwardly directed solids flow so that the solids flow comes into contact with the gas flow.

摘要： A reactor chamber of a fluidized bed reactor has an internal circulation of particles. Larger recirculated particles are prevented from contacting heat transfer surfaces by classifying particles adjacent the bottoms of the reactor chamber using a particle chamber having a barrier wall with holes or slots of a maximum dimension of less than about 30 mm. The heat transfer surfaces may be disposed in the particle chamber. Larger particles flow down the walls of the particle chamber into the reactor chamber, and some fine particles within the particle chamber are preferably recirculated back to the fluidized bed. The barrier wall is preferably the top wall of the particle chamber, and may be refractory lined with furrows, and/or may be formed of water tubes connected together by fins, with the holes or slots formed in the fins.

摘要： A method of and apparatus for controlling heat transfer in a fluidized bed reactor having a heat transfer chamber (312) with a bed (314) of solid particles therein, means (320,322) for introducing fluidizing gas into the heat transfer chamber for fluidizing the bed of solid particles therein and heat transfer surfaces (316) in contact with the bed of solid particles in the heat transfer chamber. Heat is transferred to said heat transfer surfaces from the solid particles. The fluidization of the bed of solid particles is varied according to a periodical function, e.g. by control means (34) periodically varying the flow velocity of fluidizing gas being introduced into the heat transfer chamber. Thereby the instantaneous heat transfer, as well as, the effective heat transfer from solid particles to the heat transfer surfaces may be controlled.
