Corrosion Test and Analysis of Condenser Copper Tubes in Thermal Power Plant

In order to investigate the corrosion influence of various factors of the circulating cooling water in condenser copper tubes in Zhangjiakou Power Plant, based on a complete analysis of water quality of the cooling water, corro- sion and scale inhibition tests have been implemented using two corrosion and scale inhibitors ZD-1 and ZD-2, respectively. Then corrosion tests of various influencing factors of the cooling water on three kinds of condenser copper tubes have been conducted. Test results show that, ZD-1 and ZD-2 have very similar performance in corrosion and scale effects, and they can both meet the actual requirements of production;B30 tube is superior to 701-A and 701-B tubes in its corrosion resistance;Cl- plays a dominating role in corrosion tests compared with other influencing fac- tors, and it causes a severe corrosion impact on 701-A tube ,while corroding B30 tube weakly ;the highest concentration of NaClO antiseptic should be controlled below 4.4mg/L,otherwise a much higher concentration will impede the corrosion inhibition of corrosion and scale inhibitors, and sterilization can be achieved when maintaining the concentration at approximately 1.1 mg/L.
