Abstract: In order to improve the boiler efficiency, latent heat recovery from the flue gas is very important concept. Thermal-hydraulic behavior of heat exchangers for the latent heat recovery was investigated experimentally by using an actual flue gas from a propane gas fuel boiler. Three kinds of tubes, bare tubes and spirally finned tubes of pitch 5 and 10 mm, were installed in the test heat exchanger. The parametric studies varying the fuel flow rate, temperature and flow rate of feed water were conducted. Based on the previous basic studies, a prediction method for the heat exchanger was proposed. The experimental results for the heat exchanger with bare or finned tubes agreed well with the prediction.
