ABSTRACT:
A melting furnace for treating wastes is provided which has a container equipped with a feed port for a glass raw material and wastes to be treated at the top thereof and a discharge port for molten glass containing said wastes at the bottom thereof, the container having a wall made of a heat resistant alloy and the container wall being in contact with molten glass inside the container; a heating electrode disposed in the container, the container wall acting as a counter electrode for the heating electrode; and a cooling system disposed at the back side of the container wall. By directly supplying electric power to the glass means disposed at the back side of the container wall.
By directly supplying electric power to the glass between the container wall and the heating electrode, the molten glass containing the wastes can be formed. By conducting cooling of the container wall by the cooling system, corrosion of the wall due to the atmosphere in the container can be restricted.
