This study provides a comprehensive experimental and numerical comparison of the oxyfuelOxyfuel burner system with air–fuel configurationConfiguration, for launderLaunders preheating in a full-scale setup. The results demonstrate that an oxyfuelOxyfuel combustionCombustion system significantly enhances temperature uniformity and launderLaunders heating rates, achieving these benefits with the same energy input as conventional air–fuel systems. Notably, the adoption of this burner system reduces flue gas volumes by approximately 65–70% compared to traditional air–fuel burners, while maintaining comparable firing rates. Furthermore, CFD simulationsCFD simulation are shown to be effective in optimizing the placement and distributionDistribution of burners along the launderLaunders. These findings underscore the potential of oxyfuelOxyfuel technologyTechnology to improve both operational efficiencyOperational Efficiency and environmental performancePerformance.
