ABSTRACT:
A method of combustion and a fluidized bed incinerator for burning and decomposing refuse such as municipal wastes are disclosed. The refuse is fluidized together with a fluidizing medium such as sand and primary air, to form a fluidized bed where the refuse is burned and decomposed. The pyrolysis gas produce by thermal decomposition of the refuse is combusted with secondary air supplied to the incinerator. By controlling the temperature inside the fluidized bed so as to be maintained in the range from 520.degree. to 650.degree. C., stable combustion is achieved, despite changes in the volume of refuse added to the fluidized bed, and the unburned pyrolysis gas and smut densities in the exhaust gas are decreased. Temperature control is achieved by spraying water onto the fluidized bed. The combustion air ratio can be reduced because the refuse can be stably combusted, and the temperature of pyrolysis gas inside the combustion chamber can be maintained at a high level.
