This report summarizes the results of a two-year laboratory study undertaken to develop data under simulated flow conditions that will provide better insight on different condenser corrosion problems and practical alternatives for their solution. The study acquired comparative data on various forms of corrosion as related to sulfide pollution of cooling water, cooling water temperature, and suspended sand in the cooling water. The effect of cathodic protection applied at different levels was also investigated. The program included four typical condenser tube alloys (titanium, 90-10 Cu-Ni, 70-30 Cu-Ni, aluminum brass) and two tubesheet alloys (Muntz metal, aluminum bronze-alloy D). The results demonstrated that: (1) sulfide pollution of condenser cooling water can greatly aggravate various forms of condenser corrosion and can impede cathodic protection (2) suspended sand in condenser cooling water may increase tube corrosion rates (3) cooling water temperature can directly affect the extent and degree to which various forms of corrosion will tend to occur and (4) cathodic protection can be used to mitigate selected forms of condenser corrosion. 18 refs., 50 figs., 29 tabs.
