    摘要: A means for cleaning a gas distributor of a fluidized bed comprises a pneumatic motion imparting means, such as a gas jet, for imparting motion to a cleaning medium, such that the medium strikes the gas distributor from the gas input side thereof with sufficient momentum to chip or scrape off at least a portion of any particulate matter adhering to a surface thereof. The gas jet preferably operates intermittently to maintain heat exchange efficiency and preferably is allowed to nutate to increase the area cleaned. In the method for cleaning the gas distributor, the cleaning medium is larger than the gas passages of the gas distributor. In another configuration, the cleaning medium is of the same material as the fluidized material and is smaller than the gas passages of the gas distributor, thus allowing at least a portion of the cleaning medium to pass through the distributor. The cleaning medium is replenished from the fluidized material.
