Abstract:
This paper analyzed the principle and characteristics of various water treatment methods, and the technical principles and key points of weak oxygenated treatment(WOT) were introduced. The WOT for 660 MW supercritical DC furnace unit was carried out, and the WOT mode operating condition control was discussed, and the performance was evaluated. The results showed that the scale formation and salt deposition rate of the thermal system and scale growth and peeling of oxide scale could be obviously reduced by using the WOT. Thus, it significantly improved the safe operation level and corrosion protection level of the unit, and had excellent economic and environmental benefits.
