ABSTRACT:
There is provided a method of incinerating a waste material to process incineration residues produced in a gasification furnace easily with existing equipment. A combustible gas generated when a waste material A is dry-distilled in a gasification furnace1is introduced into a combustion furnace3and combusted therein. The combustible gas is generated in the gasification furnace1in order to keep the temperature in the combustion furnace3at a temperature capable of melting incineration residues. The incineration residues are charged into the combustion furnace3while the combustible gas is being combusted therein, and melted into a melted material B that is discharged from an outlet3of the combustion furnace3into a receptacle33in which the melted material B is solidified. Air supplied to an air jacket6and oxygen supplied to the gasification furnace1and the combustion furnace 3 are heated by a heat exchange with waste gases from the combustion furnace3.The heat exchange is carried out by providing a heat exchanger36with a conduit8disposed therein in a passage of the waste gases from the combustion furnace4, and passing air or oxygen through the conduit8upstream in the passage of the waste gases.
