Comparison of Finned-Tube and Plate-Finned Heat Exchangers in Waste Heat Recovery
The use of waste heat recovery devices on mobile units (trucks and ships) is usually limited by the available space and the application of compact heat exchangers is recommended for such purposes. The performance of the heat exchanger is defined by the optimized Rankine cycle (to achieve maximum power) and it depends on the mass flow and temperature of the flue gases and selection of the working fluid in Rankine cycle. An example of selection of the preheater performance (in case of water as the working fluid) is considered here, wherein the several surface types of finned tube and plate-finned heat exchangers are used, for which there are measured data of the heat transfer coefficient and friction factor. Heat exchangers are sized according to the criteria of maximum allowed velocity of the flue gases and shapes of the heat exchanger frontal area. The sized heat exchangers were compared with respect to the heat transfer coefficient, the area of the heat exchanger surface on the finned side, the volume of the heat exchanger and the pressure drop on both sides. It is concluded that the plate-finned heat exchangers have a smaller heat transfer area, i.e. a smaller volume at an acceptable pressure drop.
