摘要
介绍了核电站广泛使用的两类原理和结构不同的除氧器,详细分析和论证了其各自的优缺点后指出,淋水盘式除氧器在加热性能上略优于鼓泡管式除氧器,除氧性能两者相当,而鼓泡管式除氧器则在特殊工况下的运行稳定性和维护保养的便利性方面稍优于淋水盘式除氧器。提出了核电站大型除氧器的合理选型原则。
The paper introduces two kinds of deaerator with different principles and structures which are widely used in nuclear power stations.By analyzing advantages and disadvantages of the deaerator,it is pointed out that the disc-flow type deaerator is slightly better than the bubbling pipe type on the aspect of heating performance,and their deaerating capabilities are equivalent.However,on the aspect of operation stability and maintenance convenience,the bubbling pipe type deaerator is better than the disc-flow type under special working conditions.Selection principles for large-sized deaerators of nuclear power stations are finally presented.
