Book excerpt: This study was performed to establish a conceptual design and cost evaluation of an advanced technology mechanical draft wet/dry and natural draft dry cooling systems for large electric power plants using a high performance integral fin-tube heat transfer surface. This study was part of an overall DOE program to develop and demonstrate advanced concept cooling systems for large electric power plants. The results obtained show significant economic advantages compared to results previously published for conventional cooling systems. These advantages are due to the higher heat transfer and lower pressure loss which occur with the use of the selected multi-port integral fin-tubes.

Available in PDF, EPUB and Kindle. Book excerpt: The objectives of this program were to establish a conceptual and preliminary design of a forced draft dry cooling system using high performance integral fin-tubes developed by Curtiss-Wright and to establish projected costs of this system for use in large electric power plants. These investigations are an extension of a previous study, which showed that significant performance and cost savings were potentially available with the use of these advanced technology integral fin-tube heat transfer elements when used in forced or induced draft dry cooling towers. An attempt is made to delineate and quantify these potential cost savings and to investigate further the installation factors associated with the use of these fin-tubes in a dry cooling system. The results obtained show significant economic advantages compared to results previously published for a conventional dry cooling system. These advantages are due to the higher heat transfer and lower pressure loss which occur with the use of the selected multi-port integral fin-tubes.

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: Experiments were performed to assess the operating characteristics and potential performance of water-augmented dry cooling systems. The work was aimed at evaluating a deluged air-cooled HOETERV plate fin heat exchanger surface proposed for integrated dry/wet cooling systems and using test results to guide the development of a predictive analytical model. In the process, all-dry performance data were obtained for the HOETERV surface as well as for two Curtiss-Wright chipped fin surfaces. The dry heat transfer data indicate that a slotted Curtiss-Wright surface slightly outperforms the HOETERV and nonslotted Curtiss-Wright surfaces based on heat rejection rate per unit of fan power. However, all three surfaces are so close in performance that other factors, such as surface cost and piping and mounting costs, will probably determine which surface is preferred at a given installation. Comparisons of deluged HOETERV performance with dry HOETERV and Curtiss-Wright performance under prototypic conditions have established that deluging can provide considerable heat rejection enhancement, particularly at low ITD and low air humidity. A deluged HOETERV core operating at a 115°F primary fluid temperature in 105°F air at 10% relative humidity can reject over 7 times as much heat as a dry HOETERV core operating under the same conditions at the same air-side pressure drop. Deluged tests were performed to evaluate the effect of airflow rate, deluge flow rate and core tilt angle on performance. Both increased airflow and increased deluge flow increase both heat rejection rate and required fan power. Optimal airflow rate will thus be determined for a given location by the competing costs of heat exchanger surface area versus fan operation. Changes in core tilt angle from vertical to 16° from vertical have a negligible effect on performance.

Available in PDF, EPUB and Kindle. Book excerpt: The use of combined dry/wet cooling systems for large base-load power plants offers the potential for significant water savings as compared to evaporatively cooled power plants and significant cost savings in comparison to dry cooled power plants. The results of a detailed engineering and cost study of one type of dry/wet cooling system are described. In the ''deluge'' dry/wet cooling method, a finned-tube heat exchanger is designed to operate in the dry mode up to a given ambient temperature. To avoid the degradation of performance for higher ambient temperatures, water (the delugeate) is distributed over a portion of the heat exchanger surface to enhance the cooling process by evaporation. The deluge system used in this study is termed the HOETERV system. The HOETERV deluge system uses a horizontal-tube, vertical-plate-finned heat exchanger. The delugeate is distributed at the top of the heat exchanger and is allowed to fall by gravity in a thin film on the face of the plate fin. Ammonia is used as the indirect heat transfer medium between the turbine exhaust steam and the ambient air. Steam is condensed by boiling ammonia in a condenser/reboiler. The ammonia is condensed in the heat exchanger by inducing airflow over the plate fins. Various design parameters of the cooling system have been studied to evaluate their impact on the optimum cooling system design and the power-plant/utility-system interface. Annual water availability was the most significant design parameter. Others included site meteorology, heat exchanger configuration and air flow, number and size of towers, fan system design, and turbine operation. It was concluded from this study that the HOETERV deluge system of dry/wet cooling, using ammonia as an intermediate heat transfer medium, offers the potential for significant cost savings compared with all-dry cooling, while achieving substantially reduced water consumption as compared to an evaporatively cooled power plant.
