Research on Blowing Technology for Secondary Side in HTR-PM Steam Generator
-
摘要: 基于国内高温气冷堆示范工程(HTR-PM)蒸汽发生器(SG)二次侧的清洁问题,提出压缩空气吹扫技术。通过对SG二次侧螺旋管汽-液两相和单向流特性的分析,得到吹管系数的计算方法。根据HTR-PM机组的设计参数进行实例计算,得出压缩空气吹扫可行性方案。Abstract: Based on the cleaning of the secondary side in High-Temperature Gas-cooled Reactor（HTR-PM） steam generator. the compressed air blowing technology are proposed in this paper. Through the analysis on the flow behavior of steam-water two-phase or one-phase in helical coils of the secondary side in the steam generator,the method of blowing coefficient was introduced.According to the design parameters of the unit, the result showed that the compressed air blowing technology is feasible.
