摘要
以理论计算为基础,找出了主冷器壳程循环水流量小是由于其进口处加防冲板后,管束处的入口面积远小于进口管截面积引起的。为增大管柬处流通面积,一是减小排管数量,二是改用防冲挡管结构。
Based on theoretical calculation,this article finds out the reason for the small circulating water flow in shell side of main cooler,i.e.the entry area in bundles is much smaller than the sectional area of inlet tube after the impact baffle is installed at the inlet,and provides some measures for improvement.
