摘要

For condensation from a steam-gas mixture, analogy correlations of heat and mass transfer taking account of the mass absorption effect on the wall were proposed in the previous study. These correlations gave good predictions on heat exchanger calculations when the concentration of non-condensing gas was more than 75. The analogy method is preferable for the design of heat exchangers where the heat transfer correlations have been empirically established. However, at the concentration less than 75, some modification was necessary on the mass transfer correlation because it was originated and estimated from the heat transfer correlation without condensation. Condensation heat transfer on a row of horizontal stainless steel tubes was investigated experimentally in the non-condensing gas concentration of 0～78 and new analogy relation covering the wide range was proposed.
