ABSTRACT:
A method of melting an incineration residue includes steps of: charging an incineration residue containing salts into a melting furnace; heating the charged incineration residue in the melting furnace to produce a melt which includes a molten slag layer and a molten salt layer on the molten slag layer; controlling a temperature of the molten salt in the molten salt layer; discharging the molten slag from the melting furnace; and discharging the molten salt from the melting furnace. An apparatus for melting an incineration residue includes: a melting furnace main body, having a molten slag hold-up section and a molten salt hold-up section on the molten slag hold-up section, into which an incineration residue containing salts is charged; a charging device for charging the incineration residue in the melting furnace main body; a heating device for melting the charged incineration residue to produce a melt comprising a molten slag in the molten slag hold-up section and a molten salt being in the molten salt hold-up section; a control device for controlling a temperature of the molten salt in the molten salt hold-up section; a slag discharge port for discharging the molten slag from the molten slag hold-up section; and a salt discharge port for discharging the molten salt from the molten salt hold-up section.
