For example in the power generation field, as the thermal power generation occupied 60% of the power generation demand, the improvement of the thermal efficiency is required considerably. This paper described that the heat transfer characteristics of the finned tube banks used for the heat exchanger in the thermal power generation were clarified by testing the serrated finned tubes banks with different fin height for improvement of higher heat transfer and the conventional spiral finned tube banks with different fin height, and that the equation to predict heat transfer coefficient which is neccessary on design of the heat exchanger was proposed.
