    摘要: A separator for separating solid particles from a hot gas stream comprises a cyclone chamber having an axial gas outlet conduit. The outlet conduit is formed by a plurality of cooling tubes defining between the tubes a plurality of passages for the gas. The outlet conduit is connected to an opening in one or both ends of the cyclone chamber. Solids are separated by centrifugal forces as the gas flows in a curved path in the cyclone chamber and by inertia forces as the gas changes direction to flow into the outlet conduit.

    摘要: A simple yet effective method and apparatus control the temperature within a fluidized bed reactor within a desired range (e.g. about 800.degree.-950.degree. C.). Particulate solids in the off-gases from the combustion chamber of the reactor are separated out, and pass through one or more of a plurality of return conduits back to the combustion chamber. The temperature of the returning solids is controlled by positively cooling them, utilizing heat exchangers, within one or more of the conduits, and by controlling which of the conduits the solids flow through. Valves at the top of the conduits can control the flow of solids into the conduits. Alternatively U-shaped passageways at the bottom of the conduits between them and the combustion chamber can have fluidizing air injected therein, the injected air controlling the flow of solids out of the conduits into the combustion chamber.

    摘要: A fluidized bed reactor uses fluid conduits for supplying fluids (such as liquid, gaseous, or fine solid material in suspension fuels), into a reactor chamber. The fluid conduits extend horizontally from, and substantially perpendicularly to, a side wall into the reactor chamber. The fluid conduits are disposed at a level (e.g. about 100-1000 mm) above the fluidizing gas nozzles in the bottom of the reactor chamber. An upright partition, preferably of refractory material, covers the fluid conduits.

    摘要: A fluidized bed reactor e.g. for the burning of fuels of different calorific values. The bottom part of the combustion chamber is divided into an outer and an inner fluidization zone by a partition wall adjacent to the distributor plate. Heat transfer surfaces are disposed in the outer fluidization zone. Heat can be withdrawn from the outer fluidization zone which is activated when burning fuel having a high calorific value. When burning fuel of lower calorific value the outer fluidization zone is not operated. The inner fluidization zone will be in operation in both cases. The supply of fluidizing gas to the second fluidization zone is controlled in order to maintain predetermined conditions in this zone.

    摘要: A method and an apparatus for separating coarse and fine solid particles from flue gases in a circulating fluidized bed reactor provide for flue gases to be led to a cyclone separator, located adjacent the reactor. A discharge opening is provided in the lower portion of the separator, opening into a suction chamber interposed between the discharge opening and a return duct. Coarse particles are returned to the reactor via the return duct while fine particles are pulled into a suction pipe connected to the suction chamber, and are then returned to the reactor separately from the coarse particles. At the same time, a minor portion of the flue gases are removed through the discharge opening in the separator with the solid particles and returned to the reactor. The major portion of the flue gases is discharged through an opening in the upper portion of the separator.
