Ash melting furnaces using combustion are used to treat incineration residue. The improvement of running costs is being required for the furnaces, because a great quantity of energy is being consumed in them. Lower energy consumption in the IHI burner melting furnace was achieved by both reduction in size of the furnace and utilization of residual carbon within the residue. Such an improvement is attributed to the high intensity combustion. In this study, the ratio of combustibles in the residue was varied from 0% to 67% by adding the coal and using a thermal decomposition product. As the ratio of the combustibles was increased, fuel consumption reduced. When the ratio of combustibles was above 41%, no fuel was necessary without the influence on melting performance. Also the relationship between the reduction in fuel consumption and the combustion phenomenon has been discussed.
