摘要
介绍了某超临界600 MW汽轮机带负荷能力的下降情况,通过对机组运行和试验参数的计算、对比,分析了通流部分的效率变化,指出出力下降的原因是通流面积变小。
The issue of output drop of a supercritical 600 MW steam turbine is described. By calculating and comparing the running and test parameters of the unit, the efficiency changes in the flow section of the turbine are analyzed and it is concluded that the cause of the problem is the diminution of turbine flow area.
