| Abstract: | The issues are discussed on higher LP extract temperature existing in the 300 - 600 MW class subcritical and supercritical units made by Shanghai Turbine Plant（STP）. According to the client＇ s feedback, field inquiry and analysis, the problem is caused by the leakage in LP inner casing. In order to solve it, the LP inner casing is redesigned, introducing the operating experiences for USC units. The new upgraded unit is indicated to be more efficient and have lower coal consumption. |
