があった。By the way, in the fluidized bed incinerator 1 described above, if the operation is performed with the minimum amount of fluidized air required for fluidization, the incineration material supplied from the dust supply port 2 can be removed. Non-combustible materials such as metal pieces such as wires and cans and debris etc. contained therein do not fall through the gaps between the diffuser tubes 6 and accumulate over one or more diffuser tubes 6. There is. If incombustibles accumulate on the air diffuser 6, fluidization is hindered, and a good combustion state of the incinerator cannot be maintained, and long-term continuous operation cannot be performed. For this reason, conventionally, the amount of fluidizing air (primary air) supplied to the air diffuser 6 is unavoidably set to about 1.5 times the minimum amount of air necessary for fluidizing, and the fluidizing state is increased. Although the incombustibles are prevented from accumulating on the trachea 6, they are not completely prevented, and the operation is often stopped. In addition, when the supply amount of the primary air from the air diffuser 6 increases, fluidization of the fluidized bed becomes intense, local combustion proceeds, and the amount of secondary air decreases, so that good combustion can be maintained. There was no problem.

いるが、構造が複雑になる問題がある。On the other hand, in a diffuser plate type fluidized bed incinerator, accumulation of incombustible materials on the diffuser plate is inevitable.
For example, as disclosed in Japanese Utility Model Application Laid-Open No. 60-83895, a rotating arm for removing incombustible substances is provided on a diffuser plate, and the non-combustible substances accumulated on the diffuser plate are removed by the rotating arm outside the furnace. Although discharge is performed, it is not preferable to provide a mechanical movable member on the diffuser plate. For this reason, Japanese Patent Application Laid-Open No. 63-271
As in 016, the hearth is inclined from the furnace wall toward the center of the furnace, and incombustibles deposited on the hearth are moved along the inclination and discharged out of the furnace. However, since the fluidized state is not uniform when the hearth is inclined, the lower surface of the inclined diffuser plate is partitioned by a plurality of wind boxes, and the amount of fluidizing air supplied to each wind box is changed to make the fluidized bed uniform. However, there is a problem that the structure becomes complicated.
