Book excerpt: The projected cost of five alternative dry/wet power plant heat rejection concepts was studied under conditions imposed by hypothetical use in association with the San Juan Plant Unit 3, a 550-MWe facility currently under construction near the ''Four Corners'' area of New Mexico. The five alternative concepts were: integrated dry/wet tower; separate dry and wet towers; metal fin-tube induced draft tower with deluge water augmentation; plastic heat exchanger tower with deluge water augmentation, and metal fin-tube/deluge augmentation tower with an intermediate ammonia evaporation-condensation condenser and the cooling tower. The integrated dry/wet tower concept, already chosen for service at San Juan Unit 3, was included for reference purposes. All concepts were conceptually designed and estimated using the same bases and employing uniform practices. Each concept was assumed to use all water allocated for consumptive use in Unit 3. The cost estimates obtained showed the following descending order of ''comparable capital cost'': separate dry/wet; metal fin-tube/deluge; integrated dry/wet; plastic tube/deluge; and metal fin-tube/deluge/ammonia. The results indicate that two of the advanced concepts considered, i.e., the plastic tube/deluge concept and the metal fin tube/deluge/ammonia concept, can possibly reduce the overall costs of dry/wet cooling under conditions imposed by the site considered. It was recommended that these two concepts receive additional attention by the ERDA Dry Cooling Tower Program and industry to further quantify their potential benefits and demonstrate their performance and reliability.

This book was released on 1978 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The projected costs of five alternative wet/dry power plant heat rejection concepts were studied under conditions imposed by hypothetical use in association with the San Juan Unit 3 plant, a fossil-fuel 550-MWe facility currently under construction near the ''Four Corners'' area of New Mexico. Four of the cooling systems use ammonia as a heat transfer medium between the steam condenser and the heat rejection tower, while the fifth uses the condenser cooling water for heat transport. The four alternative concepts were: the HOTERV plate fin with deluge augmented cooling (vertical round towers); the HOTERV plate fin with deluge augmented cooling (horizontal configuration); the separate channel augmented tower (SCAT); a Curtiss-Wright extruded tube with integral fins, augmented with water flowing internally through separate channels, and the augmenting ammonia condenser (AAC); Curtiss-Wright tube augmented with a separate water-cooled condenser close-coupled to a conventional wet tower. The state-of-the-art method was the integrated wet/dry tower currently being constructed at the San Juan Unit 3 station. The comparable capital cost of each of the five concepts was calculated. Fuel savings resulting from using each of the advanced concepts vis-a-vis the reference integrated wet-dry cooling towers, expressed in barrels of oil per year, were calculated. The study indicates that the ammonia system with either the deluge scheme for wet/dry cooling, using the HOTERV plate fin heat exchange, or the Curtiss-Wright chipped-fin surface, (using either the SCAT arrangement or the separate water-cooled ammonia condenser for augmentation) are potentially more cost-effective than the state-of-the-art system for use in a power plant heat rejection system. This has been shown specifically only under conditions imposed by the site at the San Juan plant.

Book excerpt: The purpose of this year's work has been to develop a new dry cooling tower surface. The new surface utilizes a modification of film type packing in wet cooling towers. It is a concept which may eliminate excessive water loss. Cost of fabrication, and effectiveness of heat transfer surface were among the major design considerations. Based on preliminary water wetting investigations over simple geometric surfaces, a conductive plate was shaped to form a series of V-troughs. It provided open channeled water flow separated by fin-like dry surfaces, and simultaneously self distributed random spraying water. The design not only channels the water flow, but also provides a convenient means to vary the air-water interfacial area to the water-plate and dry plate contact area. Varying these ratios will become necessary as optimization studies are completed. To investigate the effectiveness of this design and of future advanced wet-dry concepts, a model heat transfer test apparatus was constructed. It provided operating conditions (water temperature, water flow rates and air flow rates) similar to those of existing wet cooling tower packing sections. All of the design requirements have been satisfied: hot water flow recirculation and counter flow air stream. A computer simulation of the proposed surface was made. The simulation modeled heat and mass transfer from the air-water interface as well as heat transfer from the dry surface area. Initial parametric runs were made using the program. They indicate that when the ratio of wet surface area to total surface area is five percent, approximately seventy-five percent of the energy transfer takes place as sensible heat transfer; whereas, for a wet tower at similar conditions approximately eighty-five percent of the total energy transfer takes place by evaporation.
