A method of stable combustion in a fluidized bed incinerator for burning and decomposing refuse such as municipal wastes while fluidizing them is disclosed. A number of air diffuser tubes are provided inside the incinerator body for fluidizing the refuse and the fluidizing medium. The fluidizing air from the air diffuser tubes is supplied at high speed or low speed from each of the tubes respectively. By alternately forming more and less fluidized areas inside the fluidized bed, the refuse is stably burned. Because of the stable combustion of the refuse, the combustion air ratio can be reduced and the combustion chamber temperature inside the incinerator can be maintained at a high level.
