  • Methods and apparatus for enhancing combustion and operational efficiency in a glass melting furnace
    Patent number: 4911744
    Abstract: In a glass melting furnace of the type that has a basin wherein a bath of molten glass is heated by a blanket of flame that extends over the molten bath, performance and productivity are enhanced by installing oxygen injection lances through holes that are drilled through walls of the furnace at tuck stone levels just above the top surface of the molten bath of glass in the furnace basin. The lances are thin walled tubes that each carry an adjustable flange for preventing unwanted convection and radiation through furnace wall holes that receive the lances.
