摘　　要：结合外高桥第二发电厂两台900MW超临界锅炉,对给水加氧运行工况下水汽品质的检测和分析:给水箱出口、除氧器进口和省煤器进口的氧含量都控制在一定范围内,说明加氧效果显著,系统内含氧量确实较除氧运行有明显的提升;并且蒸汽管道内Fe、Cl离子等成分均能达到要求,可以看出加氧运行的可行性。Based on two 900MW supercritical boilers in Waigaoqiao Second Power Plant,the detection and analysis of water and steam quality under feedwater oxygenated treatment conditions:the oxygen content at the outlet of the feedwater tank,the inlet of the deaerator,and the inlet of the economizer are all controlled within a certain range,indicating significant oxygenation effect,and the system's oxygen content is indeed significantly improved compared to deoxygenation operation;And the components such as Fe and Cl ions in the steam pipeline can meet the requirements,indicating the feasibility of oxygenation operation.
