A fluid bed combustion chamber (1) is equipped with cyclones (4, 5, 6) for purifying exhaust fumes. These cyclones are equipped with devices (15, 16, 17) for feeding ashes out into them; the device has a pipe system comprised of pipe pieces welded together in angles for deflection of the flow through the system that is surrounded by cooling cylinders. In order to heat up the cyclones before the start of the combustion chamber and therefore avoid condensation from the exhaust gases a medium to warm the cyclones can be made to flow through, preferably hot water, at the same time as pressurised air from a compressor (18) is led backward through the pipe system and into the cyclones.<IMAGE> |
