摘要： A process and furnace for melting glass is set forth wherein the majority of the combustion energy over the melting zone of the furnace is provided by oxy-fuel combustion while a majority of the combustion energy over the fining zone of the furnace is provided by air-fuel combustion. In many cases, it will be preferable to provide greater than 70% and up to and including 100% of the combustion energy over the melting zone by oxy-fuel combustion and greater than 70% and up to and including 100% of the combustion energy over the fining zone by air-fuel combustion. By proper tailoring of the combustion space atmosphere through oxy-fuel and air-fuel firing, the present invention can result in an improvement in glass productivity and quality. The present invention can be applied in the construction of a new furnace or can be applied to existing air-fuel furnaces.

摘要： Oxygen-enhanced combustion in a manufacturing plant using a nitrogen plant to obtain a nitrogen product stream for use in the plant is effected by utilizing the oxygen-rich vent, waste, or exhaust stream as the primary source of oxidant for combustion of fuel in burners used to heat furnaces and the like in the same plant. Processes according to the invention employ a vent stream in place of a high purity oxygen stream for oxy-fuel combustion, oxygen lancing, and oxygen boosting.
