Abstract: A new type of passive containment cooling system of nuclear power plant has been put forward in previous research. The effect of non-condensable gases on steam condensation over tube external surface is a key factor to evaluate the heat removal capacity of the system. Experiments of steam condensation over inclined tube external surface under different pressure, wall subcooling and air mass fraction have been carried out. The results show that the steam condensation heat transfer coefficient over inclined tube increases with the decrease of air mass fraction and wall subcooling. The increase of pressure can also enhance the heat transfer coefficient. The inclined tube has a better heat transfer performance than vertical tube’s.
