The combustion chamber A is brought to a high temperature state of 1300 ° C. or higher under high temperature heating by a ceramic heater. The input garbage and other incineration wastes burn. The exhaust gas generated at this time flows into the exhaust gas combustion chamber B, reheats and burns, and is then sent to the exhaust gas pipe 21 of the exhaust gas water cooling chamber C. In the exhaust gas water cooling chamber C, the heated exhaust gas is cooled and sent from the lower end of the exhaust gas pipe 21 to the bubble generating portion (sintered metal) 25 below the exhaust gas water cooling chamber C.

Is scattered and thinned to increase the surface area of the liquid combustion product to increase the combustion efficiency, and the liquid combustion product is burned and incinerated while maintaining a high temperature in the furnace chamber.

The operation of the present invention for treating the incineration ash attached to the rotating disk body (furnace chamber bottom wall) is the same as that of the first embodiment described above. In addition, since the combustion chamber A and the crushing incineration ash chamber D become negative pressure by combustion, it is possible to take in by natural suction from the combustion air port 10 or the incineration ash suction port 30, but in the embodiment of FIG. Since the combustion air supply device F is provided, the combustion air port 10 and the incineration ash suction port 30 are closed, the combustion chamber A and the crushing incineration ash chamber D are sealed, and the combustion air pressurized by the combustion air supply device F is used. (Further, if desired, exhaust gas cooling is utilized to heat the combustion air to preheat the combustion air), and the combustion temperature in the combustion chamber A is raised to increase the combustion efficiency by supplying the air through the vent holes 8.
By keeping the combustion chamber A and the crushing incineration ash chamber D in a sealed state, it is possible to prevent a slight odor from leaking and maintain the environment around the incinerator in a good condition.
