PURPOSE:To obtain the fluidized bed incinerating device which is able to burn sufficiently any waste having low heat release value without requiring auxiliary fuel, and perform effectively the heat recovery by a method wherein the center of a heat recovery part is deviated from the center of a fluidized be in horizontal direction. CONSTITUTION:A water cooled wall 26 of a waste-heat boiler 8 acts as a heat recovery part for recovering an incinerating heat generated at the waste incineration by the heat exchanging due to the contact between the radiation heat from a flame at the lower part of a free board 7 and a burning exhaust gas passing through a gas cooling chamber 9. By deviating a center line 29 of the heat recovery part for a center line 15 of a fluidized bed 4 with a distance (l) in horizontal direction, the radiating cooling action from the heat recovery part becomes small, the temperature of the fluidized bed 4 and the flame temperature of a free board 7 are maintained at high level, accordingly, the excellent burning can be maintained without disturbing the self-burning. Further, the heat recovering quantity in a water pipe group 10 other than the water cooled wall 26 can be increased, the heat recovering efficiency can be improved. |
