The operation of the embodiment constructed as described above will be described below. First, high-calorie waste such as tires and plastics is charged into the primary combustion chamber 30, and incineration materials such as general waste and industrial waste including tires are inserted into the secondary combustion chamber 31. Next, the incinerator in the primary combustion chamber 30 is ignited and blown by the blower 36 to burn the incinerator. The purpose of the combustion in this case is to gasify the incinerated material, and therefore, it is burned at a low temperature (about 350 °). Next, the gas generated in the primary combustion chamber 30 is passed through the communication pipe 3.
The igniter 41 ignites in the middle of steps 2 and 33, and is sent to the secondary combustion chamber 31 together with air from a blower (not shown) to heat and burn the incinerated material in the secondary combustion chamber 31.
