汽轮机甩负荷后有头式淋水盘除氧器的瞬态分析

Transient Operation Analysis of Tray Type Deaerator in Load Rejection Condition of Turbine

通过实例介绍了汽轮机甩负荷后除氧器瞬态压力、闪蒸蒸汽、闪蒸蒸汽流速、通过平衡管的压降以及淋水盘堆压降与时间的关系,评估汽轮机甩负荷对除氧器的运行影响,从而获得除氧器内部结构设计的关键点。

The relationship between the transient pressure of deaerator,flash steam,flash steam flow velocity,pressure drop through balancing pipe,stack pressure drop of tray and time after load rejection of steam turbine is introduced through an example.The influence of load rejection of steam turbine on deaerator operation is evaluated,and the key points of deaerator internal structure design are obtained.
