Abstract
A method for combusting combustible gases generated by thermal decomposition of refuse in a fluidized bed incinerator is disclosed. The refuse is fluidized, together with a fluidizing medium such as sand, by the primary air, burned and decomposed. The pyrolysis gas produced by the decomposition of the refuse is completely burned by the secondary air introduced into the combustion chamber of the incinerator in a grid-shaped pattern, in multiple stages. The noncombustible gas and smut densities within exhaust gas are also reduced. Additionally, the combustion chamber temperature can be maintained at a high level as a result of the secondary combustion being carried out quickly.
