The steam turbine is a machine regards steam as the work substance , and transforms thermal energy into kinetic energy of steam flow 汽轮机是以水蒸汽为工质,将热能转变为机械能的高速旋转式原动机。
The steam path of the steam turbine through which steam flows consists of nozzles , and the moving blade , fixed blade and other auxiliary equipment 汽轮机的通流部分即蒸汽流过并做功的部分,其中包括喷嘴,隔板以及动、静叶片以及相应的汽封装置。
The steam flows through two large diameter ducts ( 2000 ) to the condenser . steam enters from this distribution manifold into the finned tubes at the top of the primary condensing bundles 蒸汽通过1个大孔径管道( 2000 )分为两个管道( 1600 )流入凝汽器。蒸汽通过配汽集管进入一次冷凝管束顶部的翅片管道。
The study also shows that the unidentified steam leak quantity is not exceeded to 0 . 3 % of the main steam flow after the system is isolated . so the steam leak of the thermal system is little , and the system is sealed well 研究结果还表明,系统隔离后不明泄漏量均不超过主汽流量的0 . 3 % ,整个热力系统外漏量较少,系统严密程度较好。
