| Abstract: | This paper introduced the significance of real time on line monitoring of power plant condensing steam pipe corrosion and the principle of weak polarization electrochemical corrosion rate measurement.Through the combination of linear polarization method and weak polarization method,the corrosion rate and polarization resistance were measured.The on line electrochemical corrosion rate measurement techniques,which developed by the Institute of Metal Research,Chinese Academy of Science,was used to monitor the condenser tube and carbon steel pipe corrosion rate in Tianjin Datang Power Generation Co.,Ltd.Application results show that the on line electrochemical corrosion rate measurement is accurate and the power plant managers could use this system to guide the addition of corrosion inhibitors. |
| Keywords: | corrosion electrochemical weak polarization on line monitoring condenser circulating cooling water |
