How Air Products Helps Aluminum Producers
Air Product’s Transient Heating Oxy-fuel Burner , a novel melting technology, uses zonal temperature sensors and flame movement to direct energy preferentially to the aluminum and provide needs-based, sensor-driven, superior spatial and temporal energy distribution in the furnace in order to minimize overheating and aluminum oxidation. The Transient Heating Oxy-fuel Burner is usually mounted on the furnace roof and typically has four nozzles directed toward four quadrants of the furnace below the burner. Using proprietary control techniques coupled with temperature feedback, the burner can direct heat to any combination of the four quadrants. When installed on a reverb furnace, the Transient Heating Oxy-fuel Burner helps to:
- Prevent overheating and non-uniform temperature distribution by delivering heat to where it is needed in the furnace.
- Prevent oxidation and melt losses by creating a reducing atmosphere near the melt.
- Minimize NOx generation by lowering flame temperature via staging of fuel and oxygen.
Compared to baseline air–fuel operation, implementation of Transient Heating Oxy-fuel Burner burner technology can achieve a 48% decrease in specific fuel consumption, 35% improvement in productivity, and 20% reduction in melt loss.
