Heat transfer characteristics of a spirally finned tube bank with a staggered tube arrangement for waste heat recovery from the hot gas have been experimentally investigated. The finned tube banks used in this study have a tube arrangement, tube dimension, and fin material different to that of air-cooled heat exchangers. It is shown that the heat transfer characteristics of these finned tube banks differs greatly from those of the finned tube with the equilateral triangular tube geometry for the air-cooled heat exchangers. The new heat transfer correlation for the prediction of the heat transfer coefficient of the finned tube banks for waste heat recovery is induced concerning the effect of the nonequilateral tube geometry, which differs from that of anair-cooled heat exchanger.
