A USER'S MANUAL FOR THE BNW-ⅠOPTIMIZATION CODE FOR DRY-COOLED POWER PLANTS VOLUME Ⅰ

摘要

This User's Manual provides information on the use and operation of three versions of BNW-I, a computer code developed by Battelle, Pacific Northwest Laboratory (PNL) as a part of its activities under the ERDA Dry Cooling Tower Program. These three versions of BNW-I were used as reported elsewhere to obtain comparative incremental costs of electrical power pro¬duction by two advanced concepts (one using plastic heat exchangers and one using ammonia as an intermediate heat transfer fluid) and a state-of-the-art system.nThe computer program offers a comprehensive method of evaluating the cost savings potential of dry-cooled heat rejection systems and components for power plants. This method goes beyond simple "figure-of-merit" optimi¬zation of the cooling tower and includes such items as the cost of replace¬ment capacity needed on an annual basis, and the optimum split between plant scale-up and replacement capacity, as well as the purchase and operating costs of all major heat rejection components.
