The combustion chamber must be at least 1,100 ℃ to completely burn the contaminants such as dioxin. Therefore, during combustion, the temperature of the first combustion chamber is raised to 1,300∼1,500 ℃, so if it is not completely insulated from the inner wall of the combustion chamber, the temperature rises to the outer wall of the combustion chamber. In the present invention, the inner wall of the combustion chamber was triple-insulated with refractory bricks, castable and high temperature bricks, thereby lowering the temperature of the outer wall of the combustion chamber to 80 ° C or lower. The heat-resistant material layer 102 of the inner wall of the combustion chamber may use any other material as long as it can provide perfect insulation even without using the material. Rotating plate 111 and the injection nozzle 112 and the oxygen supply pipe (130, 150) of the combustion device 110 installed in the combustion chamber should use a special heat-resistant steel with heat resistance and corrosion resistance that the waste fuel can withstand high temperatures.
