To prevent the fall of temperature of molten slag and effectively supply the molten slag to a slag receiving vessel when the molten slag is discharged from a slag outlet port of a vessel to supply the slag to the slag receiving vessel in an ash melting furnace.
The ash melting furnace comprises the vessel 1 having conductivity and including an ash inlet port 2 and the slag outlet port 3 for melting ash supplied from the ash inlet port 2 and discharging the formed molten slag , a vessel inductively heating coil 2 which externally surrounds the vessel to generate induction current in the vessel, a slag supply duct 5 with conductivity provided from the slag outlet port 3 of the vessel to the slag receiving vessel 6 provided separately from the vessel to supply the molten slag discharged from the slag outlet port 3 to the slag receiving vessel 6 and a duct inductively heating coil 14 disposed outside the duct 5 to supply the induction current to the wall of the duct and generate heat.
