Abstract:
A method for melting an incineration residue containing salts comprising the steps of:adding a component adjustor to an incineration residue containing salts to adjust a component molar ratio determined by the following equation in the range of 0.7 to 2.0: component molar ratio=(Ca+Mg)/(Si+Al); charging the incineration residue having an adjusted component molar ratio into a melting furnace maintained in a reducing atmosphere, and melting the incineration residue to form a melt; maintaining the melt in the melting furnace to separate the melt into a molten slag layer, a molten salt layer and a molten metal layer; fractionating the molten slag and discharging the molten slag; and rapidly cooling the discharged molten slag.
