Separating device for precipitating solid particles from the gas flow of a fluidized bed

A separating device for precipitating solid particles from a gas flow, comprising:

• a circulating fluidized-bed reactor conducting a gas flow carrying solid particles with a given entraining force;
• and
• a device for influencing the gas flow to permit centrifugal and gravitational forces greater than said given entraining force to act on the solid particles and cause the solid particles of a specific minimum size to be separated from the gas flow, said device including:
• a flow channel directing from top to bottom the gas flow emerging from said reactor along a circular arc around a horizontally disposed cyclone axis, the gas flow experiencing the centrifugal and gravitational forces as the gas flow traverses said circular arc for separating the solid particles of the specific minimum size from the gas flow;
• a take-over channel disposed next to said flow channel for receiving and passing on the gas flow cleaned of the separated solid particles from said flow channel;
• and
• a separating chamber into which said flow channel merges vertically and expands downwardly for sinking precipitated separated solid particles into said separating chamber.
