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.

摘要： Injecting one or opposed gaseous streams into the atmosphere over molten glassmaking materials in a glassmelting furnace, in a region of the refining zone, improves the quality of the glassmelt and lessens the risk of crown corrosion.

摘要： A burner (20) has a central port (9) and three or more outer ports (1-8) whose axes are angled toward or away from the central port axis (39). Sequentially varying the outer port(s) from which material is injected at a high enough momentum to deflect the flame from the axis (39) of the central port changes the orientation of the flame with respect to the central port axis (39).

摘要： A system for removing and purifying a carbon dioxide-containing stream from a batch process tool is provided. A multi-phase contaminated stream containing at least carbon dioxide and one or more co-solvent is removed from a process tool and conveyed to at least one intermediate pressure separator. The contaminant-containing stream is separated into an intermediate pressure carbon dioxide-enriched vapor stream and an intermediate pressure solvent and contaminant-enriched stream in the intermediate pressure separator.
