ABSTRACT:
A combustion plant includes a circulating fluid bed, which is maintained by the supply of fuel, inert material and oxygen-containing fluidizing gas to a vertical furnace shaft. This is, at its upper end provided with an outlet for combustion gases and bed materials, which is separated from gas in a separating means, and by way of a lock is returned to the furnace shaft. The separating means is of a mechanical type, and located vertically above a further vertical shaft communicating with the lock. The further shaft encloses distribution means for the particles and a heat exchanger for cooling the particles falling from the gas stream, before they are re-introduced into the furnace shaft by way of the lock.
