影响600MW机组热经济因素的定量分析研究

Quantitative-analysis study of factors affecting thermal economics of 600 MW generating units

应用汽轮机内效率、热耗率及等效热降方法对扬州第二发电厂2台600MW机组存在的问题进行计算和分析,论述这些问题对机组经济性的影响程度、产生的原因、改进的措施及处理结果。这些问题及定量分析的方法对高参数大容量机组有一定参考价值。

The problems existing on the two 600MW generating units in Jia ng su Yangzhou Power Plant were calculated and analyzed by using the internal effi ciency,heat rate and equivalent heat drop method;and the influencing extents of these problems on the economics of units,causes of emergence,improvement measures and handling results were expounded.These problems and the quantitati ve analysis methods have a proper reference value for high parameter,large size generating units.
