The condensation heat transfer of gasoline-air mixture gas (the range of non-condensable gas mass quantity is 2%-13%) in horizontal tube was carried out. Condensation heat transfer characteristics is investigated for a horizontal tube with non-condensable gas. Condensation heat transfer coefficient could be predicted by Re and Co of liquid film. The correlation of condensation heat transfer coefficient was established.
