Book excerpt: Due to enhanced concern about water supplies and water use priorities, dry cooling systems for thermal power plants are receiving increased consideration, even though electric power from dry-cooled power plants currently costs 10 to 15 percent more than power from wet-cooled plants. A two-year study which analyzed the performance of existing dry-cooled systems and which developed economic and performance models for cost optimization of dry-cooled systems is reported. First, a design optimization code was used to compare the cost of a number of advanced all-dry systems. Then, 5 different dry/wet systems were carried through conceptual design and cost estimating. The results showed for either an all dry or a combination wet-and-dry cooling system, cost optimization can be achieved with an advanced system using ammonia as an intermediate heat exchange fluid (between the turbine and the dry tower), and that development of the ammonia concept should procede in order to provide performance and reliability data for the ammonia system.

This book was released on 1979 with total page 187 pages. Available in PDF, EPUB and Kindle. Book excerpt: The selection of waste heat rejection systems for steam-electric power plants involves a trade-off among environmental, energy and water conservation, and economic factors. This study compares four general types of cooling systems on the basis of these factors. The cooling systems chosen for study are: once-through systems including surface canals and submerged multiport diffusers; shallow closed cycle cooling ponds; mechanical and natural draft evaporative cooling towers; and mechanical draft dry towers. The cooling system comparison involves, first, an optimization of each cooling system and then a comparison among optimal systems. Comparison is made for an 800 MWe fossil unit and a 1200 MWe nuclear unit located at a hypothetical midwestern river site. A set of models has been developed to optimize the components of each cooling system based on the local meteorological and hydrological conditions at the site in accordance with a fixed demand, scalable plant concept. This concept allows one to compare the costs of producing the same net power from each plant/cooling system. Base case economic parameters were used to evaluate the optimum system for each of the four general cooling systems followed by a sensitivity study for each parameter. Comparison of energy and water consumption follows from the results of the performance model, while comparison of environmental impacts is mostly qualitative. Some quantitative modelling was performed for the environmental effects of thermal discharges from once-through systems, fogging from wet cooling towers and water consumption from the ponds, wet towers and once-through. The results of the optimization models of each of the systems are compared on the basis of: performance - discrete distributions of environmental conditions and transient simulation; economics - using base case scenarios and sensitivity values to arrive at costs expressed in terms of production costs, annualized costs and present value costs; energy and water consumption; and environmental effects. The once-through systems were found to be the least expensive of the four systems, the most energy efficient, but potentially the most environmentally damaging. On the other extreme, dry cooling towers are the most environmentally sound while being the most expensive and least energy efficient. Finally, the results of the economic optimization are compared with results from previous comparative studies.

Available in PDF, EPUB and Kindle. Book excerpt: The Dry Cooling Enhancement Program was initiated to: develop economic and performance models for cost optimization of total heat rejection systems using dry and dry/wet cooling; analyze and disseminate operating experience on existing dry-cooled plant performance; and demonstrate certain features of existing technology equipment to provide confidence for specification by utilities. The ultimate objective was to promote water conservation through industry use of dry cooling by developing and demonstrating the reliability of lower-cost systems. The economic, legal, and water availability factors that will contribute to future selection of dry and wet/dry cooling and thus influence the projected market for these types of cooling systems in the next 20 years are considered.
