Abstract

Gasket type plate heat exchanger was tested under fouling condition from seawater. Overall heat transfer coefficient, heat transfer coefficient, and pressure drop of the heat exchanger were obtained. Operational temperatures for seawater side was 10 °C, 20 °C and 30 °C and water side temperature was 5 °C, 15 °C and 25 °C. The overall heat transfer coefficients increased by 12% with increase of the seawater flow rate at the same temperature range, and increased from 7.5% to 14.5% with increase of the temperature on both sides under the same flow conditions. The heat transfer coefficient for seawater side increased by 7% - 19% with increase of seawater flow rate under the same temperature condition. The pressure drop was less than 3 kPa depending on the temperature, but increased by 34 kPa with increase of the flow rate.
