ABSTRACT:
Waste is combusted by an incinerator and becomes an ash. The ash is transferred to a melting furnace to be melt therein. The ash contains unburned carbon and the melting at the melting furnace is influenced by an amount of the unburned carbon. The amount of unburned carbon largely depends on a gas temperature at an waste inlet of the incinerator and an waste burn-out point in the incinerator. The waste disposal method, using the incinerator and the melting furnace, comprises the steps of detecting the gas temperature at the waste inlet of the incinerator, detecting the burn-out point of waste combustion in the incinerator, controlling a waste transfer speed in the incinerator and controlling a flow rate of air fed into the incinerator such that the detected temperature and burn-out point remain within repsective predetermined ranges, which in turn brings the amount of the unburned carbon remaining in the ash to a desired value, whereby the melting at the melting furnace is controlled to a desired melting.
