    • 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.

    • 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.

    • 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.
