Cooling water fouling of compact heat exchangers.

Author(s) : THONON B., GRILLOT J. M.

Summary

Plate heat exchangers are commonly used in industrial processes, as they are more efficient and more compact than classical shell and tube heat exchangers. Their high heat transfer temperature performances lead plate heat exchangers to be more sensitive to fouling. Several studies have shown that the fouling resistance values for plate heat exchangers are significantly lower than for plain tubes. Some experiments on particulate fouling have been carried out on two industrial plate heat exchangers. The results clearly indicate that the asymptotic fouling resistance is inversely proportional to the velocity square and that there is a strong geometrical effect. Furthermore, the measured fouling resistances are nearly 10 times lower than the values recommended by the TEMA (Tubular Exchanger Manufacturers Association, USA) for plain tubes.
