The Third International Conference on Film Forming Substances(FFS 2019)

摘要

plication review of the plant or chemistry as per Section 8 in the IAPWS TGD,and that there was no understanding why a polyacrylate addition was included in the proprietary FFAP.1.The experience in nuclear plants continues to be good with ODA being the FFA of choice.There was low impact on the chemistry control with complete observation of hydrophobic films in the feedwater and condensate as well as cycle clearance.However,film formation in dry steam areas is still a question.2.Whereas there is a full wide range of FFS being applied to the other plants,and the experience in fossil and combined cycle plants continues to be variable in terms of corrosion product transport and film formation in steam circuits.Suggestions were made to improve the verification process using tube samples and corrosion product monitoring during startups.
