For condensation from a steam-gas mixture flowing normal to horizontal rows of tubes, an approximate equation was obtained with an analogy relation between heat and mass transfer taking account of the mass absorption effect on the wall in the previous study. These correlations gave good predictions when the non-condensing gas fraction was more than 75%. At the fraction less than 75%, some modification is necessary on the mass transfer correlation because it was obtained from the heat transfer correlation without the condensation. Condensation heat transfer on horizontal stainless steel tubes was investigated experimentally for the modification of mass transfer correlation. The experiment was conducted in a wide range of non-condensing gas fraction and the modification was proposed.
