| Abstract: | An analysis is given of the impact, which the fouling of a shell-and-tube seawater heat exchanger at the tube side and the resulting changes in heat transfer intensity and flow pressure drop will have on the exergy loss of the heat exchanger. A method is proposed to evaluate heat exchanger fouling condition by making use of the exergy loss factor. This method has been found to be more comprehensive and straightforward for evaluating heat exchanger fouling than the one based on heat resistance detection and measurement. |
