摘要： An inner shroud portion and an outer shroud portion dividedly formed per stationary blade are formed integrally with each stationary blade. A plurality of the stationary blades adjacent to each other in a circumferential direction are coupled together by a band member at the outer shroud portions. The inner shroud portions are held between seal holders which are formed as two divided members in the flowing direction of a working fluid, which are fastened by a bolt, and which have a length corresponding to the plurality of the stationary blades. The plurality of stationary blades, the inner and outer shroud portions, the band member, and the seal holders assembled in this manner constitute a unit. A plurality of the units are connected in the circumferential direction to constitute a stationary blade ring of an axial compressor.

摘要： Gas turbine starting method is improved to start operation with bleed valves being first throttled, then fully opened on the way and then fully closed at 90% speed, thereby fluid unstableness phenomenon is suppressed and starter motor power is reduced. While inlet guide vane (11) and variable stator vanes (C1 to C5) are set to predetermined opening from starting to rated speed, bleed valves (1, 2, 3) are set to predetermined opening until 52% speed for the bleed valve (1) and until 51% speed each for the bleed valves (2, 3), then the bleed valves (1, 2, 3) are fully opened until the speed exceeds 90%, when they are fully closed for rated operation. In the prior art, starting operation is done with bleed valves being first fully opened until the speed is elevated to 90% and then fully closed, but in the present invention, air discharged into ambient air in vain can be reduced and thereby starter motor power can be also reduced.
摘要翻译：燃气轮机启动方法得到改进，首先节流排气阀开始运行，然后在途中完全打开，然后以90％的速度完全关闭，从而抑制液体不稳定现象，起动电机功率降低。当入口引导叶片（11）和可变定子叶片（C1至C5）被设定为从开始到额定速度的预定开度时，放气阀（1,2,3）被设定为预定的开度直到排放阀的52％ 1），直到排放阀（2,3）的速度提高到51％，然后当额定运行完全关闭时，排气阀（1,2,3）完全打开，直到速度超过90％。在现有技术中，开始操作是通过首先完全打开放气阀直到速度提升到90％然后完全关闭的方式进行的，但是在本发明中，可以减少排放到环境空气中的空气，从而起动电动机功率也可以减少。
