Abstract

PURPOSE:To eliminate troubles like jamming of incombustible or combustible matter and to keep smooth flow of a fluidizing medium in a fluidized bed type heat-reactive furnace used as an incinerator or the like, by constructing the furnace to have a single internal space without providing any partitions for diving the internal space of the furnace. CONSTITUTION:Refuse put into a furnace from a refuse inlet port 60 is drawn into the flow of a fluidizing medium and gets into the top of a downward moving layer 46, so that it is burnt in the layer 46 and a fluidized bed 10. In the internal space of the furnace defined by furnace walls 61, a distribution plate 42 and a top section 59, no partitions are provided for dividing the internal space of the furnace, so that flow of the fluidizing medium is not disturbed, and incombustible foreign matter having a fairly large size can be also moved and discharged to the outside smoothly from an incombustible-matter outlet port 48.
