    摘要: A circulating fluidized bed reactor is provided that includes a reaction chamber having a vertical partition wall forming two independent subchambers that include a combustion subchamber and a cooling subchamber. A combustion fluidizing gas is provided to the combustion subchamber to maintain a circulating fluidized bed therein. At least one centrifugal separator receives flue gas from the combustion subchamber and separates particles from the flue gas. At least one external bed receives the particles from the at least one centrifugal separator and provides the particles to the combustion subchamber. An external bed fluidizing gas is provided to the external bed to fluidize the particles therein. The cooling subchamber cools the external bed fluidizing gas received from the external bed. A heat exchanger cage receives the flue gas from the centrifugal separator and the external bed fluidizing gas from the cooling subchamber.

    摘要: The method consists in causing the flue gases to pass through a filter placed inside the recovery boiler so that the fly ash contained in said flue gases can be hot filtered out. An additional flow (B) of a material is superposed on the flow of fly ash to be filtered, which material has characteristics such that it increases the melting point of the fly ash by forming high melting point eutectics so as to facilitate unclogging by preventing viscous bridges from forming between the particles of fly ash. Application to hot scrubbing of flue gases generated by burning household refuse.

    摘要: A refuse recycling system which recycles municipal waste as energy, includes a shredder for shredding the waste and removing rejects via a feed pipe to a circulating fluidized bed reactor, the reactor producing flue gases. The reactor includes a side dense fluidized bed situated on the wall of the reactor which is provided with the feed pipe, the side dense fluidized bed extracting non-fluidizable heavy elements and transporting them to a coarse-particle sorter apparatus via an extraction duct disposed at a base of the side dense fluidized bed. At least a portion of the rejects from the shredder is fed into the coarse-particle sorter apparatus. The coarse-particle sorter apparatus cools the elements and extracts non-fluidizable inert matter from the elements, the remaining matter being fed back into the reactor. A module for recovering energy and for treating the flue gases output by said reactor is connected downstream from the reactor.

    摘要: A circulating fluidized bed reactor includes a lower zone having a fluidization grid, primary and secondary air injection inlets, and fuel feed inlets, an upper zone, internal bubbling beds at the top of the lower zone collecting solid matter from recirculation internal to the reactor and delivering a fraction thereof to external bubbling bed heat exchangers close coupled with the walls of the reactor level with the internal beds. The external heat exchangers reject the solid matter into the lower zone after exchanging heat with an external fluid. The reactor is simple in structure and benefits from the advantages of bubbling external beds while maintaining conventional design in the lower zone.

At least one heat-exchanger component (25, 26, 27) is placed in the recirculation cyclone (2). Pipe lines (30) enable air to be injected in tangential directions into the upper part of the cyclone (2) and thereby to increase the vortex effect. The combustion takes place substantially in the upper part of the cyclone (2). The fluidization column (1) comprises a widened section (1a) in its lower part.

    摘要: An installation for combustion (1) of carbon-containing solids includes an oxide reducing reactor (2), a first cyclone (5), a recuperator (6), an oxidation reactor (3), a second cyclone (4), wherein flows an oxide which is reduced then oxidized in each of the two reactors (2 and 3). In the installation, the fuel is ground before being introduced into the reduction reactor (3). The reduced size of the solid fuel particles enables more complete and faster combustion and enables almost 100% production of fly ashes which are separated from the circulating oxides.
