Abstract: Given that the furnace burner has to be switched to process burner before feeding the raw gas reformer during its start-up, the paper studies the fuel and raw material switching process during the furnace drying and feeding processes at the start-up stage. It proposes to develop an integrated raw gas reformer burner for both the drying and feeding procedures, which can serve throughout the whole process from drying to start-up through automated control programs. The paper describes the research and development process of the integrated burner, and demonstrates the ignition feasibility of the integrated burner from the the ignition test conditions for switching fuel to raw material, and illustrates the structural design of the integrated burner and the design of the automation control program. The results show that the integrated raw gas burner can effectively solve the safety hazards in the process of switching burners, reduce the consumption of start-up and reach the leading edge of similar equipment in terms of service life and process performance.
