In order to investigate the impact of the air for sulfation on the operational status of the copper flash smelting waste heat boilers, this paper takes an industrial copper flash smelting waste heat boiler as the research subject and employs Fluent software for simulation calculations. The flow field, temperature field, and flue dust particle trajectories inside the boiler under conditions with and without the air for sulfation are compared. The results indicate that after introducing the air for sulfation, significant changes occurred in the velocity distribution, temperature distribution, and heat exchange effect in the boiler. When the air for sulfation is introduced, the gas flow in the radiant chamber is less likely to cause direct ceiling impact, and the average temperature of the gas flow in the radiant chamber is slightly lower than that under conditions without the air for sulfation. However, in the convection chamber, the average temperature of the gas flow is slightly higher under conditions with the air for sulfation compared to that without air for sulfation. The simulation results not only deepen the understanding of field process personnel regarding the influence mechanisms of the air for sulfation, but also provide theoretical support for optimizing operational adjustments, thereby enhancing the overall performance and stability of the waste heat boiler.
