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. This article discusses added performance and emissions benefits that can be realised in oxy-fuel systems through the use of a technique known as oxygen staging.
