Conceptual Design and Cost Evaluation of a High Performance Dry Cooling System

摘要

The objectives of this program were to establish a conceptual and preliminary design of a forced draft dry cooling system using high performance integral fin-tubes developed by Curtiss-Wright and to establish projected costs of this system for use in large electric power plants. These investigations are an extension of a previous study, which showed that significant performance and cost savings were potentially available with the use of these advanced technology integral fin-tube heat transfer elements when used in forced or induced draft dry cooling towers. An attempt is made to delineate and quantify these potential cost savings and to investigate further the installation factors associated with the use of these fin-tubes in a dry cooling system. The results obtained show significant economic advantages compared to results previously published for a conventional dry cooling system. These advantages are due to the higher heat transfer and lower pressure loss which occur with the use of the selected multi-port integral fin-tubes. (ERA citation 04:022595)
