Research and Improvement of Deaerators in Turbine Bypass Condition
-
摘要: 介绍核电厂汽轮机旁路系统对除氧器的要求,分析甩负荷等瞬态工况下喷雾式与淋水盘一体化除氧器内部压力等参数变化。针对瞬态工况下淋水盘式一体化除氧器内部压力迅速上升与超压问题,提出了系统优化或设备结构改进方案。Abstract: The requirement of deaerators about turbine bypass system in nuclear power station has been described in this paper. The pressure change curves of spray deaerator and tray deaerator on turbine bypass condition has also been expounded according to the calculation. The pressure of tray deaerator will increase rapidly and may be over the design pressure on transient operating condition, and some measures about system optimization or equipment improvement can resolve these problems.
