[Melting] Oxygen-Staged Combustion In Oxy-Fuel Fired Melting Furnaces

After three decades of continuous industry growth, the benefits of oxy-fuel combustion for glass melting relative to air-fuel combustion are fairly well-known and include lower capital cost, higher fuel efficiency, reduced NOx emissions and higher glass quality. In this article the author discusses added performance and emissions benefits that can be realised in oxy-fuel systems through the use of a technique known as oxygen staging.
