Abstract:
An apparatus comprising (i) a centrifugal separator assembly and (ii) a fluidized bed reactor having a reactor chamber, the separator assembly being connected to the reactor and provided for separating solid particles from gas discharged from the reactor chamber, said apparatus comprising:planar peripheral walls defining a vortex chamber, having a rectangular cross section, said vortex chamber having an interior gas volume in which at least two vertical gas vortices can be formed, and said planar peripheral walls including a first wall portion connecting the separator assembly to the reactor chamber;at least two gas outlets, disposed one after the other in the longitudinal direction of the vortex chamber, for discharging cleaned gas from the gas volume;at least one solid particles outlet for discharging separated solid particles from the gas volume; andat least one gas inlet, arranged in the first wall portion, for introducing gas from the reactor chamber into the gas volume, said at least one gas inlet including at least two inlet ducts which are mainly perpendicular to the first wall portion and arranged side by side in the first wall portion within a less than ninety degree sector of one gas vortex within the vortex chamber.
