CAP1400蒸汽发生器汽水分离装置研究

汽水分离装置是蒸汽发生器中的主要部件，其性能不仅会影响蒸汽发生器水力循环特性及水位适用性，决定上部尺寸大小，而且会影响汽轮机的正常运行。对CAP1400核电厂蒸汽发生器汽水分离装置进行了不同蒸汽负荷、饱和水量及高水位和正常水位等试验工况下的热态性能试验，获得了SP3型初级分离器与P3X型干燥器组合随蒸汽负荷、饱和水量、水位变化的分离特性。通过初级分离器和干燥器的阻力测量，分别获得了分离器和干燥器的阻力特性，对CAP1400蒸汽发生器的设计研发起到支撑作用。

Research of Steam-water Separation Equipment of Steam Generator for CAP1400

Steam‐water separation equipment ,as one of the main components of steam generator ,affects steam generator hydraulic recirculation performance as well as water level adaption ,determines the size of steam generator upper shell and assures stable operation of steam turbine . Hot rig tests of CAP1400 steam generator steam‐water separation equipment were conducted under various steam loads ,saturated water flow rates ,normal and high water levels .Separation characteristics of SP3 primary separator and P3X dryer varying to steam load ,saturated water flow rate and water level were obtained . Resistance characteristics of primary separator and dryer were obtained respectively by measuring resistance .T he test results lay a foundation for the research and development of the CAP1400 steam generator .
