摘　　要：针对在装1 000MW汽轮机组的结构特点,提出了节能降耗的一些改进措施,并在机组安装及调试过程中实施。该机组试运后与已投运的同类型机组相比,节能效果显著,仅高、中压缸效率分别提高1.5%和0.2%。Aiming at the structural features of a 1 000 WM turbine unit in installation, some improvement measures were put forward and implemented for energy conservation and consumption reduction during installation and commissioning of the unit. Compared with other same type units already put into operation, the unit has achieved significant energy saving effect in trial run, with the efficiency of high- and medium-pressure cylinder increased by 0.5% and 0.2% respectively.
