The oxygenated treatment can effectively prevent flow accelerated corrosion in feed water system and high pressure heater drain system

which becomes the optimal water treatment measure for(ultra) supercritical units. By simultaneously oxygenating to both the feed water and high pressure heater drain

the fully protection oxygenated treatment technology can significantly reduce the mass concentration of iron in feed-water and high pressure heater drain. The feed water is treated with precise aerobic hypoxia

the steam basically contains no dissolved oxygen before and after the oxygenation

so there is no risk in promoting the concentrated shedding of oxide scale in the steam system. This oxygenated process is safe and reliable. Application of this fully protection automatic oxygenated treatment technology in ultra-supercritical 1 000 MW units in Shenwan Anqing Electric Power Plant shows that

the application effect is good

the water vapor system can be fully protected

the theory and the practice prove that the this fully protection automatic oxygenated treatment process with air as the medium does not affect the water quality of the feed water.
