Aiming at the problem that the nitrogen oxide emission concentration of the hot rolling reheating furnace in Chaoyang Iron & Steel Co., Ltd. of Ansteel Group Cor., Ltd. exceeded the standard and failed to meet the standard stably, the low-nitrogen combustion technology was formulated and applied combined with the actual production of the ASP hot rolling reheating furnace. On the basis of maintaining the heating capacity of the original burners unchanged, the top flat-flame burners and bottom heating adjustable-flame burners were replaced with low-nitrogen oxide environmental protection burners, and supporting technologies such as heating capacity configuration, combustion gas flow control, atmosphere control, and oxygen content monitoring were implemented. After application, the nitrogen oxide emission concentration was decreased from 182 mg/m3 to 93 mg/m3, and the fuel consumption was saved by 0.01 GJ/t. It not only reduced pollutant emissions, but also lowered energy consumption, achieving the goals of energy conservation, environmental protection and green carbon reduction.
