ABSTRACT:
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.
