Abstract

A combustion plant comprises a combustion chamber (1) which is provided to enclose a fluidized bed (4) and in which a combustion of a fuel is intended to be performed while forming combustion gases. Furthermore, the plant comprises a purification device (9, 10, 11) for purifying said combustion gases. The purification device comprises a separating member (9), arranged to separate particulate material from said combustion gases, and a channel (23) connecting the separating member and the combustion chamber (1) and being arranged to recirculate the separated material to the combustion chamber (1) in which at least one distributing member (4) is provided above the orifice of the recirculating channel (23) and is arranged to provide a distribution of the recirculated separated material in the bed (4).
