In this paper, the numerical simulation of the temperature field and the velocity field of the reaction tower in the lead flash smelting furnace was carried out by the numerical simulation. The concentrate particles were tracked by the DPM model, and the particle reaction model was used to trace the particle combustion. The numerical model was verified with the thermocouple data in the industrial furnace, and the percentage error was within 4.5%. The study found that the highest temperature zone located at about 1.5m from the top of the tower. The highest SO2 concentration was in 2.5 m below the nozzle.In addition,this paper uses a central single nozzle to analyze the coke area distribution in the furnace which greatly simplified the lead smelting process. It is found that the single nozzle arrangement could have the uniform distribution of coke,which could used in the future design of the furnace.
