Beschreibung
Zusammenfassung:	A circulating fluid-bed combustion apparatus comprises a fluid-bed combustion chamber (1) having a primary combustion air inlet (5) and secondary combustion air inlet (6), the primary combustion air inlet arranged at the bottom of the fluid-bed combustion chamber and the secondary combustion air inlet being arranged in an intermediate portion of the fluid-bed combustion chamber; a layrinth separator (8) for separating coarse particles from gases, which is positioned below the secondary combustion air inlet; a heat exchanger (4), into which combustion gases are led from the fluid-bed combustion chamber; a multicyclone (9) for separating fine particles from gases discharged out of the heat exchanger; and a distributor (11) for distributing particles separated in the multicyclone to an upper zone of thefluid-bed combustion chamber above the labyrinth separator and to a lower zone of the fluid-bed combustion chamber below the labyrinth separator.
