PROBLEM TO BE SOLVED: To provide an incinerator vaporizing and melting refuse for the complete combustion of it by effectively utilizing exhaust heat. SOLUTION: An ejector 31 is provided at the boundary of the combustion chamber of the incinerator provided with a primary combustion chamber 12 and a secondary combustion chamber 13 to transfer the unburned gas of the primary combustion chamber to the secondary combustion chamber while sucking and burning it. The exhaust gas that has finished to be burned in the secondary combustion chamber 13 is allowed to flow into a high-temperature gas supply inlet 56 of a heat exchanger tank 51 through a high-temperature gas flow path 81, and separated into the gas at a high temperature containing a large amount of oxygen and the gas at a low temperature containing a large amount of carbon dioxide inside it by utilizing the differences in temperature and specific gravity. The gas at the high temperature containing a large amount of oxygen is returned to the primary combustion chamber 15 through a high-temperature gas reflux flow path 82 by using the negative pressure of the ejector 31, and refuse is further vaporized and burned by this high-temperature gas. The principal part of the part exposed to the high temperature can be manufactured of only a refractory material, and the fusion point of the refractory material is high as compared with metal materials. Thus, the problem of metal corrosion is solved while providing a simpler structure more than a conventional one, so as to permit the refuse to be incinerated completely at higher temperatures.
