Abstract

Abstract: Experiments on corrosion of TP317 and HAL77-2 immersed in papermaking intermediate water were conducted via the electrochemical method. After comparing the corrosion resistance of the two materials, it advanced the materialchoosing principle for the condenser of a new 600MW plant with the combination of heat and power. The experimental results show that in recycled water TP317 has higher corrosion resistance than HAL77-2. However, when more than 4% NaCl is added to the intermediate water, the corrosion resistance of TP317 decreases dramatically. 
