PURPOSE:To perform a steady burning by inhibiting air from partially blowing through and facilitate the removal of noncombustible objects by forming the furnace bed to downwardly incline toward its center at which a noncombustible objects removal port is disposed, and forming compartmental air boxes between the removal opening and the air box assembly side wall, each air box having a valve to regulate the flow rate. CONSTITUTION:Air introduced from a blower is divided into three lines each of which is supplied to air boxes 2a-2c situated at symmetrical positions, and is supplied into the furnace 1 from air nozzles 6. Because of this air injection, a filling fluidizing medium 8 is fluidized to form a fluidized bed 7. So that the air feed rate may be smaller from the center air box 2a to the intermediate air box 2b to the end air box 2c, each flow rate is regulated by valves 15 to maintain the fluidized bed 7 formed in the furnace in a good condition. At the central area of the fluidized bed 7, the air load is great and the fluidization is active, and so, the dropped refuse 13 is efficiently and stably incinerated. Noncombustible objects 9 contained in the refuse 13 descend and are removed from a noncombustible objects removal port 5.
