Abstract
A process for melting material to be treated includes placing material to be treated in a container that may include an insulating lining, heating the material to be treated and melting the material to be treated, preferably allowing the melted material to cool to form a vitrified and/or crystalline mass, and disposing of the mass. The mass is either disposed while contained in container or removed from container after cooling and disposed. The insulating lining may comprise one or more layers of a thermal insulating material, one or more layers of refractory material, or a combination thereof.
Claims12
A melt barrier comprising an earthen material having a melting point greater than a waste-containing melt wherein the earthen material is selected from the group consisting of rock, cobble, gravel, sand, and combinations thereof, and wherein said melt barrier defines at least a portion of a melt boundary for in-container vitrification.
