在火电厂汽轮机中，其经济性和可靠性主要取决于蒸汽流道中的去湿效果。水分在通流部分的减少，能减轻动叶片和静子部件的侵蚀损坏，而且降低了因汽轮机在甩负荷时负荷变化导致部件表面水膜闪蒸而引起的超速影响。水分的减少可以降低水膜的形成数量，从而减少水膜和汽水附面层间的摩擦损失和相间摩擦损失。水分的减少，还能减少水滴碰撞所消耗的能量，增大有效功流量，从而提高了机组的经济性和可靠性。实际上,汽轮机通流部分只能去出弥散的大水滴，而且它们在总含水量中又只占不大的比例。然而采取这种措施非常有效，因为正是这种大水滴和水膜才引起叶片以及通流部分其他元件的浸蚀，并成为湿度引起的机械损失的原因。
本文研究的目的是讨论了汽轮机湿蒸汽形成、流动特性及水分对汽轮机的影响，各项除湿法的工作过程、系统构成、除湿效果,内部除湿技术及级内蒸汽湿度监测分析，进而为实际的工程实践提供一定指导。为了更好的了解上述内容，本文研究了通过静叶空腔将水膜抽吸出流动区域，向静叶空腔内引进热量，空心静叶尾缘开设吹扫缝蒸汽吹扫与加热相结合的综合法，动叶除湿技术，动、静叶栅间隔板装置除湿技术等去湿措施。同时，介绍了汽轮机排汽湿度在线监测方法及应用研究蒸汽湿度测量方法的研究现状，并对汽轮机排汽湿度在线监测方法的进行了比较与选择。

In the power plant steam turbine, the economy and reliability of the steam flow mainly depends on to wet effect. The flow of water in part to reduce, dynamic and static blades can reduce the son of erosion damage components, and reduced because of the steam turbine load rejection load changes in parts surface water film braising and the influence caused by speeding. Water drop can reduce water the formation of biofilms quantity to reduce water film and soda with the friction between the surface loss and alternate with friction loss. Water drop, still can reduce water droplets collision energy consumption, increase effective work flow, so as to improve the efficiency and reliability of the unit. In fact, the flow of steam turbine can only go to the big drop of a dispersion, and they are in total water content and accounts for only of small scale. But such action is very effective, because it is the big drop and water film to cause the blade, and other components of the flow of erosion, and become the humidity of the cause of the loss caused by mechanical.

The purpose of this study is to discuss the wet steam turbine formation, flow characteristics and water on the influence of the steam turbine, the water removal work process, system structure, desiccant effect, internal dehumidifying technology level and in monitoring analysis of steam humidity, and then for the actual engineering practice provide some guidance. To better understand the above content, this paper studies the static leaf through the cavity water film will suction flow out of the area, to static leaves cavity introduction of quantity of heat, empty, open end trailing edge purge steam sweep and heating seam the combination of synthesis, the move leaves dehumidifying technology, dynamic and static blade partition between device dehumidifying technology, etc to wet measure. At the same time, introduces the steam turbine exhaust steam humidity online monitoring method and application research steam humidity measurement method of the research status of steam turbine exhaust steam humidity of the online monitoring method are compared with selection.

In a steam turbine in thermal power plant, the reliability and economy depends mainly on the steam flow in the dehumidifying effect. Water in the flow path decreases, can reduce the moving vane and stator component of erosion damage, and reduce the steam turbine in load rejection load changes lead to components of the surface water film flash caused by speeding effect. Water reduction can lower the water film is formed, thereby reducing water film and water boundary layer friction loss and phase friction loss. Moisture reduction, but also reduce the water droplets collision energy consumption, increase the effective power flow, thereby enhancing the economy and reliability of the unit. In fact, steam turbine flow section can only go out of diffuse large droplets, but their total water content and only a small proportion of. However, such measures are very effective, because it is this water droplets and the aqueous film caused by the blade and flow path of other components of the etching, and become the humidity caused by mechanical loss cause.

The purpose of this study is to discuss the formation of wet steam, flow characteristics and water influence on turbine, the desiccant method, system composition, working process of dehumidification, dehumidification technology and level of internal steam humidity monitoring and analysis, and then for the actual engineering practice to provide some guidance. In order to better understand the above contents, this paper studied by static blade cavity water membrane suction flow region, to the stator cavity of the introduction of heat, hollow stationary blade trailing edge slot opening blowing steam blowing and heating combination method, rotor dehumidifying technology, dynamic, static cascade spacing plate device of dehumidifier technology measures to wet. At the same time, introduced steam turbine exhaust steam moisture on-line monitoring method and Application Research of steam humidity measurement method research status, and the steam turbine exhaust steam moisture on-line monitoring method was compared with the choice.
