摘　　要：提出了一种给水在蒸汽冷却器内部分流的设计方法,采用开设主孔和调节孔的方式,通过调节孔的开和闭,解决了给水在蒸汽冷却器内部的分流和再分配,且流量调节性较好。通过实例介绍了确定主孔和调节孔流量比例的方法,从而获得分程隔板侧开孔的大小。In this paper,a design method of feedwater bypassing in steam cooler is proposed The way of opening main and adjusting holes is adopted Through opening or closing the adjusting holes,feedwater bypassing and redistributing in steam cooler is solved,with good flow regulation A real case is given to describe the method of determining the flow ratio of the main hole and adjusting holes The size of each hole in pass partition is obtained.

关 键 词：蒸汽冷却器 内部分流 主孔 调节孔 开孔直径
