摘要：Fouling of heat exchangers causes the thermal-hydrolic performance of heat-transfer equipment to decrease with time.When the thermal hydrolic performance decreases to a minimum acceptable level,the heat exchanger has to be cleaned.The decision regarding periodic cleaning of the heat exchangers is generally based on thermoeconomic performance of the process.In this paper,coolant and seawater temperatures through seawater cooled shell and tube during 2500 operating hours have been measured and total fouling resistances have been founded.The dimensionless cost model and variation with the dimensionless time is examined by considering the various cost elements for the seawater cooled shell and tube heat exchanger.
