| Abstract: | Sensible and latent heat recovery from wet flue gas is very important to improve the thermal efficiency of boilers and to save the environment. Convective condensation heat transfer of wet flue gas on the outside of a single horizontal tube was studied experimentally. The effect of inlet temperature of flue gas and cooling water, mass friction of water vapor and Reynolds number on condensation heat transfer of wet flue gas outside the horizontal tube was obtained from the analysis about the experimental data. |
