FLUIDIZED BED FURNACE AND METHOD FOR PROCESSING WASTE

摘要

The present invention relates to: a fluidized bed furnace which is capable of continuously performing adequate processing of waste, combustion of which is likely to be unstable; and a method for processing waste. A fluidized bed furnace (1) is provided with: a moving bed (21) that thermally decomposes waste and produces a thermally decomposed residue, while moving the waste downward, and a fluidized bed (22) that combusts a part of the thermally decomposed residue; a gas supply means (50) for the moving bed; a gas supply means (60) for the fluidized bed; a moving bed temperature sensor (31); a fluidized bed temperature sensor (32); and a control unit (80). The control unit (80) controls so that a gas (A2) for the fluidized bed is supplied to the fluidized bed (22) at a flow rate at which the temperature of the fluidized bed (22) is at a predetermined temperature and a gas (A1) for the moving bed is supplied to the moving bed (21) at a flow rate at which the temperature of the moving bed (21) is lower than the temperature of the fluidized bed (22) by a predetermined value.
