| 摘要 |
The present invention relates to a fluidized bed furnace and a method for treating wastes, which are capable of continuously performing appropriate treatment of wastes that are liable to cause unstable combustion. The fluidized bed furnace (1) includes a moving-bed (21) for pyrolyzing wastes into a pyrolysis residue while moving the wastes downwardly, a fluidized-bed (22) for combusting part of the pyrolysis residue, a moving-bed gas supply means (50), a fluidized-bed gas supply means (60), a moving-bed temperature detector (31), a fluidized-bed temperature detector (32), and a controller (80). The controller (80) performs a control process for supplying the fluidized-bed (22) with a fluidized-bed gas (A2) at a flow rate for causing the temperature of the fluidized-bed (22) to be a predetermined temperature and supplying the moving-bed (21) with a moving-bed gas (A1) at a flow rate for causing the temperature of the moving-bed (21) to be lower than the temperature of the fluidized-bed (22) by a predetermined temperature. |
