Abstract:
A sealed connection for a sleeve and jacket for protecting a molybdenum electrode mounted through the wall of an electric glass furnace. Around the electrode in the wall is a stainless steel sleeve coated on the inside with a fused alumina and having an outwardly extending flange at its outer end which engages the outer wall or shoulder in the aperture in the wall through which the electrode extends. The flange has an axially outwardly extending rib of V-shaped radial cross-section which seats and centers in an annular V-shaped groove around the inner end of a water jacket that surrounds the electrode outside the furnace. Refractory sealing gaskets are placed between the flange and the wall of the furnace and in the cooperating grooves and ribs of the sleeve and water jacket. The sealed cylindrical annular space around the electrode between it and the sleeve and the jacket is filled with nitrogen to prevent oxidation of the molybdenum electrode. The water jacket and sleeve are urged together and against the outer wall of the furnace by an adjustable mounting. The electrode is separately and adjustably mounted so that as the electrode wears away inside the furnace, more of it can be easily fed into the furnace.
Abstract:
A container between the output of a melting furnace wherein the molten mass is also refined, such as for glass, and the ducts to a plurality of forming machines comprising a larger first zone and a plurality of smaller second zones corresponding to each forming machine, in which container the molten mass is controlled in temperature above and below its liquid level as it flows through the first and second zone toward a forming machine so that the cross-sectional area of the molten mass at the outlet duct from each second zone has substantially a uniform temperature. Each zone is provided with temperature control means for both heating and cooling, such as burners and/or electrodes above and below the surface of the molten mass in the conditioner, and fluid jets and/or hollow ducts or panels engageable with the outside walls of the conditioner, so as to establish the desired uniform temperatures throughout the depth and width or cross-section of the molten mass flowing from each outlet duct of the conditioner and to minimize as much as possible convection currents in the conditioner.
Abstract:
A system for the treatment of waste material includes a waste-receiving module for receiving waste material and blending it with glassmaking additives. The waste-receiving module is enclosed within a waste-receiving module container which is capable of being sealed for over the road transport so that the waste-receiving module can be transported safely from one source of waste material to another without complete decontamination. The system also includes a melter module containing a melter for melting together the blended waste material and glassmaking additives to form homogeneous molten glass and thereby stabilize the waste material. The molten glass is discharged to form a vitrified waste material. The melter module is comprised of one or more melter module containers which are capable of being sealed for over the road transport so that the melter module can be transported safely from one source of waste material to another without complete decontamination. Also provided is an emission control module for receiving waste gases from the melter module and for cleaning them for discharge to the atmosphere. The entire waste treatment system can be readily disassembled, transported over the road from one source of waste material to another, and reassembled.
