摘　　要：介绍了锅炉给水加氧处理中钝化膜的形成机理和保护性能,并对某厂1000MW超超临界机组锅炉给水加氧停止后钝化膜的保护性能进行了一系列的试验。试验研究结果表明锅炉给水在停止加氧后,钝化膜在很长一段时间仍具有保护性。同时,对锅炉给水采用间断性加氧方式的可行性进行了探讨。The formation mechanism and protection performance are introduced of the passive film formed by oxgenated treatment of boiler feedwater.A series of experiments about the protection performance of the passive film are conducted after oxygenated treatment of boiler feedwater is ceased in 1000 MW ultra-supercritical units.It is shown that the passive film is also protective for a long period.Furthermore,it is feasible for the boiler feedwater to be discontinuously oxygenated.
