摘要： In a method of operating a glassmelting furnace (100) comprising a melting zone (11) and a refining zone (12), the melting zone is provided with pairs of opposed regenerators (41, 42). At least one gaseous stream or atomized fluid stream of fuel and at least one oxidant stream are injected e.g. through injectors (32, 33) and combusted into the refining zone above the molten glassmaking material to increase the average oxygen concentration in the atmosphere near said bath surface in said refining zone by 1 to 60 vol.%. The fuel and combustion air flow rates of each of said regenerator ports are adjusted to make the oxygen concentration in the flue gas exiting each of said regenerator ports located between the spring zone in the melting zone (11) and the refining zone (12) between 2 to 10 vol. %. Oxidized glass can be made and risk of crown corrosion is lessened.
