【Abstract】 The axial fuel grading technology of aero-engine was introduced into the development of burner for step heating furnace in metallurgical industry, and an industrial axial fuel grading burner was proposed.According to the production process conditions of metallurgical step heating furnace, a special experimental system for testing metallurgical burners was established, and the general engineering test method and result analysis method of industrial burners were put forward.Through the experimental test of a 1∶1 ratio industrial burner prototype, the nitrogen oxide is stable within 50 mg/Nm~3, and the temperature field distribution in the furnace is more uniform, which is conducive to uniform heating of the billet surface.The technical performance of industrial burners developed based on axial fuel classification technology meets the design requirements.At the same time, the data obtained from experimental tests can be effectively used for accurate combustion control in the actual production process, which provides a reference for the development of advanced burners and experimental tests in industrial industries.更多还原
