摘　　要：针对实际模型,借助fluent软件,应用雷诺应力模型,离散相模型和传热模型对旋风预热器内的气固两相流进行了模拟研究;通过采用不同风速的工况来进行计算,得出不同风速下预热器的收尘效率、压力损失、颗粒逗留时间,特别是很少研究的热优良度、换热效率等。并针对预热器的好坏衡量因素研究得出了最佳的风速范围。对预热器实际工作风速的选择和提高预热器的换热效率具有一定的指导意义。Aiming at the actual model, with the help of the software fluent,with the application of Reynolds stress model ,discrete phase model, heat transfer model to simulate the cyclone preheater＇s gas-solid flow; through the use of different wind conditions for the calculation, a different wind speed preheater efficiency of the filter, pressure loss, Particles stay,especially the heat transfer efficiency. Due to the result finding out the best wind speed range for the preheater. This study of Preheater has s ance for the actual choice of wind speed and improving the performance of preheater heat transfer efficiency.
