Abstract
The combustion gas passages leading to a fluidized bed in a hot water or steam boiler are kept free of deposits which might block them by pulses of gas. The gas pulses may be generated from a pressurized reservoir with periodic or aperiodic openings of a valve in a gas line leading from the reservoir to the passages. Where the bottom of a fluidized bed comprises a pair of plates defining a plenum space therebetween and the combustion gas passages define nozzles extending through the plenum space, combustion air may be fed to the nozzles via the plenum space and the cleaning pulses may also be generated from gas supplied to the plenum space.
