Abstract

Water Cooler is used widely in many systems in power plant for heat recovery or cooling purposes. A cooler is a device that allows heat energy in one process water to pass to process water in a controlled manner whose purpose is either to remove heat from water (cooling) or to add heat to raw water. Cooler are used in various systems and processes that involve the transfer of heat energy. Improper design, operation and maintenance of a cooler may result in degradation of the components due to scaling and fouling, performance of the system or unit. This paper evaluates the effects of fouling on shell and tube type in a thermal power plant. Cooler Data were obtained through steady state monitoring and direct measurements from the plant reading. The Cooler data were analyzed to determine the overall heat transfer, temperature and pressure range of hot and cold raw waters and effectiveness. The result shows that for the pump around cooler, the overall heat transfer was less than the design value. This was traceable to increased fouling that has affected the reduce effectiveness of cooler and increase temperature of sealing water. This was due to variation in temperature difference between cooler data and design value in the hot water side of the exchanger which has also affected the pressure drop. The results also show an increase the fouling factor over the design which also affected the effectiveness and capacity ratio of the cooler.
