摘　　要：利用计算流体力学(CFD)模拟方法,深入探究了三次风管不同入炉角度对分解炉性能的影响。通过对比三次风管不同入炉角度的生产情况,详细分析了入炉角度对分解炉生料分解率、气体温度分布以及生料温度分布的影响。结果显示,不同入炉角度对分解炉内流体动力学行为和传热特性产生显著影响,最佳的入炉角度能够有效提高生料的分解率,并改善气体和固体相的温度分布情况。这为分解炉的设计和操作提供了重要的理论指导和技术支持,有助于进一步优化水泥生产工艺,提高生产效率和产品质量。This study utilizes computational fluid dynamics(CFD)simulation methods to investigate the impact of different entry angles of tertiary air ducts on the performance of calciner.By comparing the situations of tertiary air ducts entering the calciner at different angles,the different effects on the decomposition rate of raw materials,gas temperature distribution,and raw material temperature distribution in the calciner are analyzed.The results show that different entry angles significantly affect the fluid dynamics and heat transfer characteristics within the calciner.The optimal entry angle demonstrates the best performance,effectively improving the decomposition efficiency of raw materials and improving the temperature distribution of gas and solid phases.This finding provides important theoretical guidance and technical support for the design and operation of calciner,facilitating further optimization of cement production processes to increase production efficiency and product quality.
