300MW汽轮机组改造后热力系统性能分析

Performance analysis on thermodynamic system of a 300MW steam turbine unit

根据谏壁电厂 9#机组改造后热力试验的有关数据 ,应用等效焓降法对回热系统进行了经济性分析计算 ,同时也分析了不明泄漏量和中压缸效率的影响 ,对进一步提高机组经济性有一定参考价值。

According to the related data of heat experimentations put up on the improved #9 unit in Jianbi Power Plant, this paper used equivalent heat fall method to analyze and calculate its heat economy; at the same time it analyzed infections from the unknown leak and the efficiency of mid-press tank, which are valuable for improving the unit heat economy further.
