Study 5: Performance of heat exchangers used in industrial processes

This study provides an overview of the current state of the art in heat recovery from industrial processes. The information summarised in this report focuses in particular on industrial furnaces and dryers in the food and drink, metallurgy and glass industries.

Following a review of the study’s context and its main objectives, this project begins with a technology review of heat recovery exchangers used in thermal processes. Next, a review of the issue of fouling in heat exchangers helps to identify future developments and the solutions being considered within the industry. Finally, five heat recovery case studies are analysed. For each case, the applicable heat exchanger technology, the nature of the effluent concerned, and existing preventive measures to limit the consequences of fouling are presented.
