摘　　要：针对超(超)临界机组给水处理方式,比较了全挥发处理(AVT)和给水加氧处理(OT)工况下热力系统氧化膜的特点,阐述了给水加氧技术的原理,分析了加氧条件及注意事项,介绍了加氧过程的实施及相关指标的控制,并通过监测结果对加氧效果进行了评价。In view of the mode of feed-water treatment for uhra-supercritical unit, the characteristics of ox- ide films in thermal system under AVT and OT conditions were compared; and then, the principle of oxygenated feed-water treatment technology was elaborated, the oxygenated conditions and the issues that needed attention were analyzed; besides, the implement of oxygen addition and the controlling of relevant indexes were also intro- duced. Finally, the effect of oxygen addition was evaluated according to the monitoring results.
