    摘要: Electrode for a glass melting furnace which avoids the disadvantages of known electrodes which are either expensive and difficult to manufacture, or have operational disadvantages, especially in regard to the delivery of electric power into the molten glass and/or in regard to trouble-free useful life. The new electrode is less costly to make and has better operational properties. The electrode shaft 2 is a coaxial tube 20 with an inner tube 21 of a metal constituting a good electrical conductor, preferably copper, and with the outer tube 22 of a mechanically strong, heat-resistant metal, preferably steel. Moreover, the electrode body 3 can be made thicker in areas of intense corrosion. The new electrode is suitable for all glass melting furnaces which are partially or entirely heated with electricity.

    摘要: Furnace has a melting section into which batch is fed to a glass bath heated by electrodes, a homogenizing section, and a clarifying section therebetween in which fossil fuel burners heat the surface of the bath. The clarifying section is separated from the melting section by a first radiation shielding wall which extends to just above the bottom of the furnace and is interrupted by an opening above the glass for passage of combustion gases from the burners. A second shielding wall extends to above the surface of the bath and below the bottom margin of the opening in the first wall, so that combustion gases flow countercurrently through the incoming batch floating on the bath.

    摘要: Glass is melted in a furnace having a melting zone and one or more processing tanks adjacent to the melting zone. Molten glass flows from the melting zone to the processing tank through a passage. A portion of the molten glass is withdrawn from the top of the processing tank and is recirculated to the processing tank or to a separate refining zone. The furnace includes a melting section and at least one adjacent processing tank communicating with the melting section through a passage. A recirculating passage connects the top of the processing tank and the passage connecting the melting section and the processing tank. Additional means are provided to establish a recirculating flow of molten glass via the recirculating passage.
