Review and Assessment of Engineering Economic Studies of Dry Cooled Electrical Generating Plants.

摘要

The major U.S. studies conducted between 1970and 1975on the economics of dry cooled electrical generating plants are reviewed. This review was undertaken to collect,compare,and summarize the approaches,assumptions,and results of several major studies on dry cooling engineering economics,and to evaluate the computer codes associated with these economic studies. From this review it was concluded that adequate detailed evaluation of state-of-the-art dry cooling systems has not been conducted and that comprehensive computer programs capable of such evaluations are not publicly available. Therefore,it is recommended that: a method for determining power production costs of dry cooled plants should be developed which reflects the actual way a utility would interface a dry cooled plant with a utility system to minimize power production costs; a comprehensive detailed evaluation of metal finned tube state-of-the-art dry cooling systems should be conducted to determine if,and where,the costs of dry cooling can be reduced;and advanced dry cooling concepts should be evaluated for potential savings in power production costs.
