A finned-tube, cross-counter-flow heat recuperator was operated on the exhaust stack of a large diesel engine. Heat transfer data was continuously monitored in order to assess the fouling of the recuperator. Relatively clean diesel fuel No. 2 accumulated a sooty deposit on the recuperator fins in a few days. Within a few weeks the heat transfer coefficient had reached a steady state. The heat exchanger has been cleaned and run through several cycles. Results are compared with earlier tests using diesel fuel No. 6 on another engine. Fouling deposits have been characterized, time variations measured, and cleaning techniques evaluated.
