Annotated Bibliography of Cooling System Literature Burger, Robert. Cooling Towers, the Overlooked Energy Conservation Profit Center. EPRI TR- 104867. 94. Notes: Addresses the question of how much improved cooling system performance is worth. Three case studies, two for power generation plants, are presented. The cost savings associated with a given temperature reduction in the cold water return temperature are given. Methods for improving the performance of existing towers are given including a review of an advanced fill to replace conventional wood packing. 7 references. Burns, J. M. et al. The Impacts of Retrofitting Cooling Towers at a Large Power Station. EPRI TR-104867 . 94. Notes: Presents a cost evaluation of retrofitting the PSE&G’s Salem Station from a once- through cooling system to recirculating, wet cooling towers. A dry cooling alternative is considered briefly but rejected on qualitative conclusions about cost and lack of experience. Cost estimates are provided but with very little information about the source of the information. A good summary of the several cost categories that must be considered is given. 3 references. Buys, J.D. and D. G. Kroeger. Cost-Optimal Design of Dry Cooling Towers Through Mathematical Programming Techniques. ASME Trans. 111, 322-327 (1989). Notes: Presents a highly mathematical treatment of the cost optimization of a natural-draft dry-cooling tower. Casts the problem as a generalized, non-linear constrained mathematical minimization problem and uses published numerical methods to accomplish the solution. Worked example is instructive. The cost functions are introduced (without derivation) but an extensive reference list may provide the basis for the algorithms. Useful only if computational packages are to be developed. 17 references. Buys, J.D. and D. G. Kroeger. Dimensioning Heat Exchangers for Existing Dry Cooling Towers. Energy Conversion and Management 29, 63-71 (1989). Notes: Develops a method for determining the optimum design of a finned tube bundle to be installed in an existing tower for which heat exchanger retrofit is desired. Example is provided for a natural draft tower and a detailed numerical case is worked through. The objective function to be minimized is the cost at a given cooling load. Sensitivity studies to illustrate the effect of varying certain independent parameters are given. 13 references. Carroll, George, D. F. Dyer, and G. Maples.

Notes: Investigated the effect of including cold water storage with conventional cooling system. Little relevance to the evaluation of wet vs. dry systems. No copy available. Choi, M. and L. R.

Notes: Program for optimization of dry cooling for power plants. The objective function to be minimized is the total evaluated cost of the cooling system. Cases were run for both fossil and nuclear plants. Lost capacity was replaced with gas turbines. The use of both conventional and high back pressure turbines was considered. The result was found to be most sensitive to A-4PDF Image | Comparison of Alternate Cooling Technologies for California Power Plants Economic, Environmental and Other Tradeoffs
