An investigation was conducted for steam condensation with high fractional CO₂ on a horizontal tube. Condensation heat transfer characteristics were obtained with a steam mixture velocity of 0.21聽m/s and CO₂ mass fraction of 11.2%-89.7%. The condensation heat transfer performance significantly deteriorated with the increase of the concentration of CO₂, decreased with the increase of surface sub-cooling and this influence decreased as the CO₂ mass fraction increased. Also, the variation amplitude of heat transfer coefficient decreased with the increase of CO₂ concentration. In addition, the correlation based on experimental data expanded its scope of application significantly compared with previous literature.
