摘要(Abstract):
汽轮机通流部分故障后必然引起相关运行参数的变化 ,变化的大小和故障的程度有关。文章分析了汽轮机通流部分故障的机理 ,并定量分析了叶片结垢或腐蚀程度与相应段压力变化量之间的关系 ,给出了仿真计算结果
The fault of turbine flow section will result in variety of thermal parameters,which depends on the fault degree. This paper first analyses the fault characteristic of turbine flow section,and provides the quantificational relation between the pressure variety and the blade encrustation or corrosion degree. Then it gives out the result of fault emulating calculation.
