摘要：

This paper presents the results of a theoretical calculation of the heat transfer of finned tubes for air-cooled heat exchangers having external operational foulings. To determine the heat resistance of the fouling layer, a problem on the temperature distribution in the ring layer has been formulated and solved. The minimum and the surface-average temperatures of the fouling, the heat resistance of the ring layer, and the heat transfer coefficient of the finned tube heat exchanger have been calculated. It has been shown that the heat transfer coefficient is the most strongly influenced by the fouling layer thickness at the base of the fins. © 2018, Springer Science+Business Media, LLC, part of Springer Nature.
