Abstract: A process of making vitrified waste in a crucible and inserting the crucible and vitrified waste into an outer container after vitrification. The outer container is then sealed.

Abstract: In an industrial glass furnace which contains recuperators, regenerators, electric boost or other devices for providing heat to glass batch material an oxy-fuel burner mounted in the roof of the furnace provides additional heat to melt the batch material. A method of mounting and using such a roof-mounted oxy-fuel burner including the operating parameters to maximize heat transfer while minimizing the disturbance of the batch material is disclosed.

Abstract: A system for melting and delivering glass to a work area such as spinners for making fiberglass includes a melter with heaters so arranged that the “hot spot” in the molten glass is located away from the walls and corrosion sensitive parts so that the various elements of the melter wear out at substantially the same time. The system is further provided with a dual exhaust arrangement when the melter, conditioner and forehearth are located on the same floor of the plant, the first exhaust being at the juncture of the melter and conditioner, and the second being an alternating replacement for one of the heating/cooling orifices and mechanisms in the conditioner, so as to effectively limit the amount of corrosive volatiles reaching the forehearth.

Abstract: Apparatus suitable for vitrifying nuclear waste comprises a tunable microwave cavity connected by a first wave guide to a source of microwave energy; cooling coils for cooling the exterior of the cavity; a hopper for loading particulate fusible material to the interior of the cavity; within the cavity a crucible made of melted and re-solidified fusible particulate material; an exit-chamber connected by a second waveguide to a second microwave source; and a pipe for supplying argon gas to the exit chamber so that a plasma torch can be generated. The separating of the crucible form the cavity walls by unmelted material gives significant advantages in case of cleaning and reduced energy consumption.

Abstract: The invention relates to a process for the production of a glass melt.

Abstract: An electric open-top melter for use in the manufacture of mineral fibers, such as fiberglass, is provided with a side-discharge outlet. The side-discharge outlet allows the melter, conditioner/refiner, and forehearth to all be located on substantially the same level, thereby allowing molten glass to flow from the side of the melter, through the conditioning zone, and into the forehearth from which spinners produce glass fibers or the like. Isolation members are provided in the conditioning or refining area so as to enable molten glass therein to be isolated from the melter and forehearth when the molten glass level is lowered below the tops the isolation members.
