摘　　要：由于无法对大型还原炉环状硅棒排布方式对能耗的影响做出准确判断,对42对棒西门子多晶硅还原炉进行仿真模拟计算,建立两种环状硅棒布棒方式(三环排布、四环排布)的还原炉模型。通过对还原炉的炉行为及棒行为分析发现,硅棒直径加大能耗也会相应加大,且这种变化受炉内流场和温度场共同影响;同时,还原炉内内环硅棒辐射能耗随硅棒直径的增大呈先增大后减小的变化趋势,而排列在外环的硅棒辐射损耗则随硅棒直径的增大而不断增大。针对42对棒西门子还原炉内硅棒的排布方法,提出选用硅棒三环排布的方式可达到降低该还原炉总能耗的目的。On account of the complexity of investigating the impact of annular silicon rod arrangement on energy consumption in Siemens polycrystalline silicon furnaces,this study establishes physical models of two annular silicon rod distribution modes in 42 pairs of furnaces:three-ring arrangements and four-ring arrangements and conducts simulation calculations.Analysis of furnace behavior and silicon rod behavior reveals that energy consumption increases with the diameter of the silicon rod,and that the flow field and temperature field influence this change in the furnace.Furthermore,the radiation energy loss with the inner ring silicon rod in the reduction furnace increases first and then decreases with the increase of the diameter of the silicon rod,while the radiation loss of the outer ring silicon rod increases with the increase of the diameter of the silicon rod.According to the arrangement method of silicon rods in 42 pairs of Siemens reduction furnace,the three-ring arrangement of silicon rods is proposed to reduce the energy consumption of the furnace and achieve the purpose of energy saving.
