Pressure drop characteristics of a spirally finned tube bank with a staggered tube arrangement for waste heat recovary form 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 pressure dorp characteristics of these finned tube banks differs greatly from these of the finned tube with the equilateral triangular tube geometry for the air-cooled heat exchangers. A new correlation for the prediction of the pressure drop in the finned tube banks for waste heat recovery is induced concerning the effect of the tube geometry, which differs from that of an air-cooled heat exchanger.
