So the proposed method in this dissertation not only meet the requirements for fossil-fuel unit set in GB/T 12145-1999, but also can effectively restrain condensate and feed water system corrosion. Thereby the proposed method can reduce the loss by corrosion's leading accident, lower Fe content in boiler feed water, slow the boiler's scaling speed, delay boiler's chemical cleaning interval, effectively enhance unit's reliability, usability and using life and solve the problem of poisonous chemical deoxidant. So the proposed method can economize substantial expense for power plant.
