一种压水堆核电站的蒸汽发生器，其具有从水和蒸汽的两相流中分离水的功能的水分分离器。近年来，随着当前和未来大型热容量电厂功率提升的要求，需要开发能够应对不断增加的蒸汽流量的高性能湿气分离器。因此，三菱重工通过在实际工厂运行条件（高压和高温）下进行验证试验，开发了高性能水分分离器（J型）。该分离器的主要特点是：小直径旋流叶片轮毂、提升管水平狭缝和下降管唇口狭缝。结合高压试验结果和热工水力分析，对蒸汽发生器出口带湿量（MCO）进行了估算。评估的结果是MCO值小于0.01%（我们的目标值：0.1%）。
A steam generator of PWR plant has moisture separators with function to separate water from two-phase flow of water and steam. Recently, corresponding to the request for power uprating of current and/or future plants with large thermal capacity, development of high performance moisture separator, which can deal with the increasing steam flow rate, has been required. Therefore, MHI has developed the moisture separator with high performance (J Model) by conducting a verification test under actual plant operating conditions (high pressure and high temperature). The developed separator’s main features are: swirl vane hub with a small diameter, horizontal slits at riser barrel, and slots with lips at the downcomer barrel. Based on the combination of the high pressure test results and thermal hydraulic analyses, value of moisture carry over (MCO) at SG outlet was evaluated. The evaluation resulted in the MCO value of less than 0.01% (our target value: 0.1%).Copyright © 2004 by ASME
