| description | PURPOSE:To provide an improved method and device for reducing the volume of incineration ash and making harmless by melting incineration ash generated by incineration of waste to vitrify and solidify it. CONSTITUTION:In a treating method by which ash 22 obtained by incineration of waste is melted in a melting furnace 1 and discharged before it is vitrified, before the incineration ash 22 is fed into the melting furnace 1, it undergoes a component composition analysis by a component analyzer 15, and at least three components, CaO, SiO2, Al2O3, are addled so that melting temp. may be |
