Fouling factors for heat exchangers
Webof shell and tube heat exchangers are affected by fouling in the design. Nesta and Bennet10 presentedguidelinestobe employed in the design of a heat exchanger to suppress fouling. Finally, Caputo et al.11 presented a heat exchanger design method, where the exchanger optimization is made with maintenance considerations. In their … Webdifferent total fouling factors . Selection of a plate heat exchanger is a trade-off between U-value (which influences surface area and hence, capital cost) and pressure drop (which influences pump head and hence, operating cost). Increasing U-value comes at the expense of increasing pressure drop. Fouling considerations for plate heat ...

Let the solution … WebSep 1, 2024 · The fouling factor represents the theoretical resistance to heat flow due to the build-up of a fouling layer on the tube surfaces of the heat exchanger. In practice fouling factors are often overstated by the end user in an attempt to minimise the frequency of cleaning.
WebThe fouling factor represents the theoretical resistance to heat flow due to the buildup of a fouling layer on the tube surfaces of the heat exchanger. In practice, fouling factor is often overstated by the end user to minimize the frequency of cleaning. If the wrong fouling factor is used, cleaning may be required more frequently.
