Abstract
PURPOSE:To eliminate a heat source and to enable stable continuous melting of incineration ash, by a method wherein, after an unburnt substance remaining in incineration ash is burnt, high temperature melting gas is guided to the downstream side of conveyance to melt incineration ash. CONSTITUTION:A waste S incinerated in an incinerator 1 produces incineration ash A to convey it from an incinerator body 3 to an after-combustion stoker 6, and operation is controlled so that a given amount of an unburnt substance remains in the incineration ash A. The incineration ash A fed from the after-combustion stoker 6 to a melting furnace 2 is burnt at a high temperature at a front part 17, and is molten as it is orderly conveyed. Melting is controlled by means of a pressure detecting device 22 and a melting gas flow rate control device 23. A controller 26 calculates a difference between pressure P1 and P2 detected by means of pressure sensors 24 and 25. When a deferential pressure DELTAP attains a given value DELTAP0, regulation of a flow rate is stopped, melting gas flows to the downstream side along the upper surface of an incinerator floor part 16, and the incineration ash A is melted, in order, in a conveyance direction E. After the molten incineration ash A is contained in a slug box 9, it is air-cooled and cured for disposal. Meanwhile, the melt gas is discharged to the outside of the incinerator after it heats air for melting.
