采用外螺旋肋片管实现高温侧强化传热后，再热器管壁温度升高，所需贵重金属耗量增加。
The temperature of the tube went up and then the expenditure of expensive alloy increased by using extern spiral finned tube, which enhanced the external heat transfer.

在进行了详细的计算分析后，发现主要是由于低温再热器进口流量分配器流量分配系数太小所致。
After a detail calculation and analysis, the reason that the flow distribution coefficient of a flow divider in the primary reheater was too small had been found.
