摘要
利用自行开发的最新凝汽器数值模拟软件对N-11220-1型电站凝汽器热力性能进行了数值分析并指出其存在的问题。然后通过反复的数值实验指出,要么加大该凝汽器管束周围蒸汽通道的尺寸,要么更换新型优化的管束才能有效改善其运行性能。
Thermal performance of the N-11220-1 power plant condenser is numerically studied using the computer program developed by author. It's pointed out that the performance of the condenser can be improved by means of either replacing the original tube bundle with a fully new more advanced one or increasing the sizes of steam lanes around the tube bundle after a series of detailed numerical experiments.
