摘要
介绍了莱芜电厂２号机改造后高压前轴封漏汽量测量原理和方法，计算出高压前轴封漏汽量，并代入热力性能试验计算过程中，核算了除掉轴封漏汽量影响的中压缸效率。此计算方法和图表普遍适用于１２５ＭＷ机组高压前轴封漏汽量的计算。
This paper presents the theory and method for measuring the HP front labyrinth leakage which is calculated based on the experimental data,and the efficiency of IP has been checked taking the HP front labyrinth leakage into consideration.This calculation method and the charts are suitable for the calculation of HP front labyrinth leakage of 125 MW units.
