Perspective ways of heat transfer enhancement for heat exchangers in fouling conditions

Abstract

The paper discusses the possibilities of intensifying the heat transfer of liquid working fluids in heat exchangers under fouling conditions. It presents a perspective on heat exchangers according to the geometry of the heat exchanger surface. The shell and tube heat exchanger with the helical flow and plate heat exchanger with the spiral flow are introduced in greater detail. These two heat exchangers are compared concerning fouling and thermal-hydraulic behavior in industrial cases. The paper shows clear advantages of these flow structures for improving these aspects. The article places a strong recommendation on the use of spiral plate heat exchangers wherever the working conditions allow.The paper discusses the possibilities of intensifying the heat transfer of liquid working fluids in heat exchangers under fouling conditions.
