    摘要: The invention relates to a circulating fluidized bed reactor designed to be fed with air and convertible to operate with an oxygen-rich mixture, comprising a reaction chamber (1) horizontally bounded by vertical walls, at least two centrifugal separators (2A, 2B) and a heat recovery element called a heat exchanger cage (3), a reactor also comprising means for introducing a fluidization gas into the reaction chamber using at least one wind box (4) placed under the reaction chamber, and for maintaining a circulating fluidized bed of particles in said chamber, means for transferring gas which must be dedusted from the chamber to the separators, means for discharging the particles separated from the separators and means for transferring the dust-free gases from the separators to the exchanger cage. According to the invention: said reaction chamber comprises at least one partially internal vertical partition wall (10) forming two subchambers (1A, 1B) communicating together and each communicating with at least one separator, said exchanger cage (3) comprises a partially internal vertical partition wall (30) forming two subcages (3A, 3B) communicating together and each communicating with at least one separator, these partition walls being arranged in order to create a passage for the flow of the flue gases into one of said subchambers and into one of said subcages corresponding to operation by oxygen feed in the reaction chamber.

    摘要: A centrifugal separator for separating particles from gas uses a separator chamber having an upper potion with at least three substantially vertical planar walls with perpendicular inner faces, and a lower portion, for defining in the chamber a vertical gas vortex. The gas vortex has an inlet formed in the vicinity of a first corner between the first and second walls for gas to be dedusted, an outlet for dedusted gas, and an outlet for separated particles. The separator uses an acceleration duct with a first transverse section at the first end of the duct that is distinctly greater than a second cross section at the second end. This second end is connected to the inlet for gas to be dedusted at the first corner.

    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.
