Abstract: Abstract:Taking the unit No.7 of Zhouxian Power Plant as example, the situation of feedwater treatment by all volatile treatment technology and oxygenation treatment technology was traced. Based on comparison of the water steam quality, the deposition on the water wall and the pressure losses of feedwater system, it was shown that the oxygenation treatment is more safe and economical operation mode for ultra supercritical oncethrough boiler unit.
