METHOD OF THE SECONDARY COMBUSTION PROMOTION FOR A FLUIDIZED BED INCINERATOR

摘要

A secondary combustion method for combustible gases generated by thermal decomposition in burning refuse such municipal wastes in a fluidized bed incinerator in which the refuse is fluidized, together with a fluidizing medium such as sand, by the primary air, and burnt and decomposed. The pyrolysis gas is completely burnt by the secondary air in a grid shape in multiple stages, which is formed inside the combustion chamber of the incinerator. The non-combustible gas and smut densities within exhaust gas are also reduced. Further, the combustion chamber temperature can be maintained at a high level by carrying out secondary combustion swiftly.
