There are many textbooks devoted to heat transfer and the design of heat exchangers ranging from the extreme theoretical to the very practical. The purpose of these publications is to provide improved understanding of the science and to give guidance on the design and operation of process heat exchangers. In many of these texts the problem of the accumulation of deposits on heat transfer surfaces is ignored or at best, dealt with through the traditional fouling resistance.
It is common knowledge that this approach is severely limited and inaccurate and may lead to gross errors in design. Furthermore the very arbitrary choice of fouling resistance more than offsets the accuracy of correlations and sophisticated methods, for the application of fundamental heat transfer knowledge.
Little attention was paid to the heat exchanger fouling and the associated inefficiencies of heat exchanger operation till the so-called "oil crisis" of the 1970s, when it became vital to make efficient use of available energy. Heat exchanger fouling of course reduces the opportunity for heat recovery with its attendant effect on primary energy demands. Since the oil crisis there has been a modest interest in obtaining knowledge regarding all aspects of heat exchanger fouling, but the investment is nowhere near as large as in the field of heat transfer as a whole.
