Air-Cooled Steam Condenser, Tube Heat Exchanger Configuration


Air-Cooled Steam Condenser is a heat exchanger consisting of an array of finned tube bundles. It consists of a primary heat exchanger, where major heat transfer takes place and secondary heat exchanger (dephlegmator) which is used to remove non-condensable from the system. The performance of an Air-Cooled Steam Condenser is influenced by the configuration of the finned tube bundles. It is significant to understand the mechanism of such influences to select the optimized configuration of the finned tube bundles. In this study Air-Cooled Steam Condenser is designed under two ambient conditions and for various finned tube bundle configuration. Finned tube bundle configuration means the number of tubes per bundle, fin density of tubes in each row, type of fins, length of the tubes and diameter of the tubes. The design calculations are targeted to a fixed power consumption for various configurations so that the relevant comparison is made for heat transfer area and flooding. The results show that flooding is intense in the lower ambient conditions hence heat duty distribution between primary heat exchanger and secondary heat exchanger is adjusted.
