| 摘要 |
The present invention relates to a fluidized bed furnace in which by forming a fixed-bed adjacent to a fluidized-bed, wastes are moved together with a fluidized medium onto the fixed-bed by utilizing a splashing action of the fluidized medium in an upper portion of the fluidized-bed, thereby allowing a reaction such as drying and pyrolysis of the wastes to proceed slowly with time, and thus the wastes can be dried and pyrolyzed slowly in the entire furnace. The fluidized bed furnace includes a base plate (30) disposed at a bottom portion of a furnace body (10) and having gas supply ports for supplying a fluidizing gas to fluidize the fluidized medium, and a fluidized bed (20) formed on the base plate (30) in the furnace body (10) to take the wastes into the fluidized medium and pyrolyze the wastes. The fluidized bed (20) has the fixed-bed (23) where the fluidized medium is kept in a resting state, and the fluidized-bed (22), formed adjacent to the fixed-bed (23), where the fluidized medium is fluidized. |
