Abstract

The purpose of this experimental work was to determine and analyze the type, rate, and causes of corrosion in the South Dakota State college steam power plant condensate lines. Since corrosion at this power plant requires an excessive amount of money for labor and pipe replacement, an investigation leading to reduction in corrosion would justify this study and would benefit other people who have to contend with the hard waters present in South Dakota. The method used to determine the rate of corrosion was the installation of a corrosion tester in the condensate discharge line of the hot water heaters of three college buildings connected to the power plant steam heating system. To determine the type of corrosion taking place, a complete chemical analysis of the condensate was required during the test run to obtain definite knowledge of the chemical reactions taking place which could cause the various types of corrosion. The results of this experimental study revealed several methods of chemical treatment that can be used in curbing corrosion damage to the steam condensate lines. Since the steam from this power plant is used in food processing as well as heating, limitations exist in applying certain types and quantities of chemicals for treating the steam produced in this power plant. These hazards of chemical treatment to the condensate were also covered in this study. The purpose of this study was to produce the possible types of treatment that can be used to retard or eliminate condensate corrosion. It is not the purpose of this study to compel a change of water treatment in this power plant operation, but rather to show that a more intensive study should be made of corrosion which might result in a change in the treatment of the water at this power plant.
