    摘要: Glass is produced in a glassmelting furnace by combusting fuel and oxidant having an oxygen content greater than 80 vol. % oxygen in a melting zone to form molten glass, wherein the surface of the molten glass is exposed to the gaseous atmosphere in the melting zone and the water vapor content of the atmosphere at the surface of the molten glass is greater than 35 vol. %, and oxidant having an oxygen content greater than 80 vol. % is injected into the refining zone of the furnace under conditions to minimize mixing of said oxidant with gases above said oxidant and sweep water vapor at the surface of the molten glass into the melting zone to lower the water vapor content of the atmosphere at the surface of the molten glass.

    摘要: Corrosion of the inner surface of the crown of a glassmelting furnace is reduced or avoided by directing at low velocity along that surface a gaseous stream comprising water vapor, or comprising the combustion products of an oxy-fuel burner operated at a stoichiometric ratio of at least 1.0, or the combustion products of a burner operated at a stoichiometric ratio less than 1.0, or by injecting into the furnace interior a gaseous reactant which reacts with alkali species in said space.
