Plate Heat Exchanger Fouling

#141 Plate heat Exchanger Fouling Definition of heat Exchanger Fouling Fouling is the degradation in heat transfer over time caused by material deposition on the heat transfer boundary walls of a heat Exchanger . As shown in Figure 1, Fouling is the reduction in the overall heat transfer coefficient (U value) over time due to this material build-up. The severity of Fouling is a function of time and the difference between the clean and fouled overall heat transfer coefficient. Figure 2 shows a cross sectional diagram of a heat transfer boundary wall with Fouling .
