摘　　要：旋风预热器是水泥预热系统中的重要组成部分,为了分析旋风预热器的气固分离效率、换热效率和系统阻力情况,对预热器进行热态数值模拟研究。在Gambit软件和流体分析软件fluent的基础上,对模型建立三维网格,采用雷诺应力模型,离散相模型和传热模型进行综合研究分析。后处理结果表明该模拟研究能够对旋风预热器实际情况进行模拟,并可用来分析旋风预热器的性能和优缺点,针对预热器缺点进行分析和优化。Cyclones Preheater is an important component of the cement preheating system. In order to analyse the gas-solid separation efficiency, heat transfer efficiency and the resistance of the preheater system, studied the cyclone preheater by thermal numerical simulation. Based on analysis of Gambit and fluid analysis software fluent, set 3D mesh for the model and studied it by Reynolds stress model, discrete phase model and heat transfer model. The results show that the simulation study can simulate the real state of the cyclone preheater and can be used to analyse the performance and advantage ＆ disadvantage of the cyclone preheater as well as the optimization.
