Summary

New fouling data are reported for plate heat exchangers (of two angles of corrugation, 30 and 60 deg) and particles of mean size approx. 5 micrometres. Fouling (under the test conditions) is adhesion controlled and the maximum measured resistance is almost an order of magnitude smaller than the TEMA recommendations. For a specific particle size, a distribution of adhesive strengths (rather than a single value) is obtained which is strongly influenced by pH and may be time-dependent for very small sizes. Various applications of the results are outlined.
