A combustion method in the fluidized bed incinerator for burning and decomposing of refuse, such as municipal wastes in which the refuse is fluidized together with a fluidizing medium, such as sand, with primary air being burnt and decomposed. The pyrolysis gas produced by thermal decomposition is combusted with the secondary air supplied to the incinerator. By controlling the temperature inside the fluidized bed in the range from 520 to 650°C by spraying water a stable combustion is, carried out, despite the change in the volume of refuse thrown onto the fluidized bed, and the unburnt pyrolysis gas and smut densities among the exhaust gas can be decreased.
