| Abstract: | Based on analysis ,the reason of the excessive temperature difference between the inside and outside of HP cylinders is found out ;the certain aspects ,containning the HP-MP regulating valve rods ,the leakage of axial seal, the control of the steam in cylinder interlayer, the drain of water in HP cylinder stator etc. ,is improved, some optimizing methods is adapted. Therefore, the temperature difference is effectively controlled. The effect of improving is quite obvious. |
