pressure. Analysis and eventual solution of the problem through modifications to the configuration of the turbine hall and the ACC windwalls is reviewed. Highlights a need for flow modeling in advance of construction. No references provided. Guyer, E. C. and D. L. Brownell. Wet/Dry Cooling for Cycling Steam-Electric Power Plants. 80. Notes: A computational procedure for incorporating utility capacity supply and energy production economics into the design criteria and operational strategy of wet/dry cooling systems. Conclusions were that there was little difference between the optimum designs for base-load and cycling plants, particularly if relatively little water was available for cooling (< 250 acre-feet per year). 16 references. Guyer, E. C. and J. A. Bartz. Dry cooling moves into the mainstream. Power Engineering . 91. Notes: A brief review of the state-of-the-art of dry cooling. At the time (~1990) the use of dry cooling was increasing in the U.S. A list of recent installations is provided. Some of the installations are described and a summary of the basic types of dry cooling systems is given. 8 references. Guyer, E. C. Dry Cooling: Perspectives on Future Needs. 91. Notes: Survey of needs for and utility attitudes toward dry cooling. A review of the environmental regulations and the then current expectations for water supply and potential shortages is given. The status of existing dry cooling systems in use at the time is provided. An historical survey of installations in the U.S. showed a significant increase in the late 1980’s up to the date of the report. An extensive review of the literature at the time is given 72 references. Hamilton, Thomas H. Developing the Worth of Colder Water in a Steam Turbine Generating Station. 2000. Cooling Tower Institute. Notes: Presents a systematic calculation procedure for evaluating the lost energy penalties associated with reduced tower performance. Examples are for wet cooling towers at steam- electric plants but the methodology applies to dry systems. Extension to combined-cycle plants is non-trivial but straight-forward. The computational scheme is detailed and laborious in this age of computerized computational tools but serves to illustrate the elements of the comparison procedure well. A useful starting point for an approach to the wet-dry comparisons. No references. Hauser, L. G. et al. An Advanced Optimization Technique for Turbine, Condenser, Cooling System Combinations. Proc. of American Power Conference. Vol. 33, p. 427-448. 71. Notes: Thorough description of the methodology for selecting the optimum cooling system and comparing optimized designs of the different classes of cooling system. Typical curves of present worth evaluation vs. cooling system performance are provided. The effect of various turbine heat rate characteristics are presented and explained. 4 references.
