PURPOSE:To have efficient power generation even in the minor range of the rate of steam flow by allowing a small and a large turbine coupled with each other to rotate a generator, and by introducing the steam only to the smaller one while the rate of flow of the steam is below a specific value. CONSTITUTION:A power generator 4 is rotated by a small 2 and a large 3 turbine. When steam generation from a steam generating device 5 is less, a steam control valve 9 is shut, and another steam control valve 8 is throttled to a proper level. If the steam S is introduced preferably to the small turbine 2, the large one 3 will idle. That will provide efficient power generation even in the minor range or the rate of steam flow to ensure suppressed cost for equipment. |
