This report presents the development and testing of a high-efficiency low-dross combustion system designed for use in aluminum remelting reverberatory furnaces, undertaken by the Gas Technology Institute and subcontractors including Eclipse Combustion, the University of Illinois at Chicago, and Wabash Alloys. The objective was to enhance environmental and energy efficiency in the secondary aluminum industry while reducing capital costs. Utilizing the Self-Optimizing Combustion System (SOCS), the innovative flex-flame burner fires either air or oxygen-enriched natural gas, employing a non-contact optical flame sensor and a sophisticated combustion control system. This setup allows for the precise management of flame shape and velocity, which is critical in minimizing oxygen exposure to the molten aluminum and, consequently, reducing dross formation. Results indicate a decrease in fuel consumption and emissions while maintaining the furnace's production rate. Although the reduced dross formation was not statistically significant, the potential for NOx reduction and efficiency maintenance was confirmed. Further R&D is recommended to explore means for deeper staging of secondary air, which may enhance dross reduction without compromising efficiency.
