ABSTRACT:
A separating device precipitates solid particles from a gas flow of a circulating fluidized-bed or CFB reactor, wherein the particles are carried along in the gas flow. A device is provided which influences the gas flow in such a way that centrifugal and gravitational forces that are greater than entraining forces of the gas flow act on the solid particles and thus permit particles of a specific minimum size to be separated from the gas flow. A particularly compact construction of a CFB system is achieved when the gas flow emerging from the CFB reactor reaches a flow channel which directs it from top to bottom along a circular arc around a horizontally disposed cyclone axis. The gas flow is fed from there to a take-over channel suitable for passing it on. The flow channel merges in a vertical direction and correspondingly expands downward into a separating chamber in which the precipitated solid particles sink down to a floor.
