FEEDER CONDUITS FOR A GLASS FURNACE

摘要

FEEDER CONDUITS FOR A GLASS FURNACE A feeder conduit is disclosed for conveying molten glass from a forehearth of a glass furnace to a glass forming machine. The feeder conduit includes an elongated conduit which receives molten glass from the forehearth and delivers the molten glass to an inlet of a bowl-shaped container. The container has an orifice in its bottom for withdrawing the molten glass therefrom and a vertical cylinder disposed within the container and above the orifice. The cylinder and side wall of the container opposite the inlet of the container define a semi-annular channel therebetween and a first electrode is inserted in the molten glass upstream of said cylinder and a second electrode is inserted in the molten glass within the semi-annular channel. The first and second electrodes are offset from the centerline of the feeder conduit. As the molten glass flows through the inlet in the container, around the cylinder and through the semi-annular channel, an electric current passes between the electrodes to heat the molten glass.
