Study on the generation law of products and economy of oxygen-deficient combustion

In response to the optimization requirements of low nitrogen combustion in gas heating furnaces, this study proposes a collaborative control method based on under oxygen combustion, which actively controls the excess air coefficient α (0.92∼1.08) to balance fuel utilization and pollutant treatment costs. Through a combination of numerical simulation and experimental verification, this study systematically analyzes the generation laws and economic characteristics of combustion products under oxygen-deficient conditions. It was found that a decrease in alpha leads to incomplete combustion of fuel, which reduces furnace thermal efficiency but significantly alters the pathway of pollutant generation. When α
