摘　　要：采用Realizable k-ε湍流模型和DO辐射模型对顶吹熔炼炉余热锅炉运行工况进行数值模拟。研究了顶吹熔炼炉余热锅炉内部流场和温度场的分布,分析了各烟道段的换热趋势以及烟气流场对换热的影响,为顶吹熔炼炉余热锅炉内部的传热流动研究提供依据,对分析实际工程中出现的问题有一定的指导意义。The numerical simulation of operation conditions of heat recovery steam generators of top-blown smelting furnace was performed with Realizable k- ε turbulence model and DO radiation model. The distributions of its in- ner flow field and temperature field were studied. The heat exchange trend of every flue sections and the effects of flue gas flow field on the heat exchange were analyzed. The results provids basis for study on the inner heat transfer and flow of heat recovery boiler of top-blown smelting furnace, and guids the analysis of problems occurring in the practical project.
