This book was released on 1992-09-30 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: Geothermal waters, hot enough to provide direct heating, are available in many parts of the world. Some are exploited already but many more are only now being considered, as planners begin to recognize the environmental benefits of this unfamiliar energy resource. The relative economic benefits are more marginal, however, and a successful scheme requires careful design and optimization. The nature of geothermal resources imposes special conditions which may be unfamiliar to many plant engineers. In addition, many different approaches are possible, depending on the characteristics of the resource and the user and on the operator's requirements. Must the scheme be optimized for energy recovery or for financial return, or is it more important that it should remain profitable over as wide a range of conditions as possible? This book, written by professional plant engineers with first-hand experience, is designed to guide plant engineers through the different options and to help in this optimization process.

Book excerpt: Methodology and data bases are described which can provide a comprehensive planning assessment of the potential for geothermal district heating in any US market. This economic systems model encompasses life-cycle costing over a period of rising competitive fuel prices, it addresses the expansion and financing of a district system over time, and it includes an overall optimization of system design. The elemental area for all analyses is the census tract, for which published data allow estimation of residential and commercial heating demands, building retrofit requirements, and competitive fuel consumption and cost. A system type design, an appropriate hot water district piping system, and costing of heat supply is performed for groups of contiguous tracts in any urban market. Groups are aggregated, in decreasing benefit to cost order, to achieve optimal systems. A specific application for Salt Lake City, Utah, is also described.

Available in PDF, EPUB and Kindle. Book excerpt: As part of our overall program of studying both the conceptual and actual set of institutional structures under which geothermal distribution systems might be formed and operated, the EWLI has also examined the institutional, economic and legal arrangements of presently functioning systems and of those in advanced planning stages. We have done this in an attempt to discover whether an analysis of the most fully developed present systems can in any way produce models on which future geothermal distribution systems might be based. The answer is problematic. ... We have chosen to discuss Boise, Klamath Falls, and Susanville because they are the most thoroughly planned, have reached the most advanced stage, are relatively large and have the longest histories of all the proposed systems. While the experiences of these cities cannot be measured against the ultimate standard of an operating history for a complete system, the formative years have produced an institutional structure for each system, a financial history related to the assumption of front-end costs, and detailed plans for development and management of the resource.

This book was released on 2005 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conceptual planning (technical, economical and politic feasibility) of geothermal district heating systems is the most important step of these projects. In this study, a conceptual planning model developed for geothermal district heating systems is applied to the project of Balcova (Izmir) System-2 Geothermal District Heating System which is on the agenda nowadays in Balçova and the technical, economic and politic feasibilities are investigated. The city section on which the geothermal district heating system will be constructed has a maximum capacity of dwellings having an area of 391,700 m2 and 80% of them have been built and are in use. The most important parameter that affects the economics of the geothermal district heating systems is the participation ratio of the dwellings in the district. In this study different participation ratio (between 100% and 26%), participation costs (between 1250$ and 1500$) and participation periods (2 or 5 years) are considered and the monthly fixed energy charge which will make the internal rate of return ratio approximately positive values around 0% are calculated.

Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on spatial planning – an important determinant of energy saving and renewable energy supply. Revealing the key driving forces for spatial development supporting the shift towards energy efficiency and renewable energy supplies, it shows the importance of integrated spatial and energy planning approaches for a timely and sustainable change of energy systems, thus supporting policies of climate protection. As operating within the context of renewable energy sources is becoming a major policy issue at the international, European and national level, spatial dimensions of renewable energy systems as well as challenges, barriers and opportunities in different spatial contexts become more important. This book analyses not only the fundamental system interrelations between resources, technologies and consumption patterns with respect to energy, but also the links to the spatial context, and provides guidelines for researchers as well as practitioners in this new, emerging field. It presents innovative analytical tools to solve real-world problems and discusses the most important fields of action in integrated spatial and energy planning including planning contents, planning visions and principles as well as planning process design and planning methodology.

Download or read book Conceptual Design Study of Geothermal District Heating of a Thirty house Subdivision in Elko Nevada Using Existing Water distribution Systems Phase III Final Technical Report October 1 1979 September 30 1980 written by and published by . This book was released on 2006 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A conceptual design study for district heating of a 30-home subdivision located near the southeast extremity of the city of Elko, Nevada is presented. While a specific residential community was used in the study, the overall approach and methodologies are believed to be generally applicable for a large number of communities where low temperature geothermal fluid is available. The proposed district heating system utilizes moderate temperature, clean domestic water and existing community culinary water supply lines. The culinary water supply is heated by a moderate temperature geothermal source using a single heat exchanger at entry to the subdivision. The heated culinary water is then pumped to the houses in the community where energy is extracted by means of a water supplied heat pump. The use of heat pumps at the individual houses allows economic heating to result from supply of relatively cool water to the community, and this precludes the necessity of supplying objectionably hot water for normal household consumption use. Each heat pump unit is isolated from the consumptive water flow such that contamination of the water supply is avoided. The community water delivery system is modified to allow recirculation within the community, and very little rework of existing water lines is required. The entire system coefficient of performance (COP) for a typical year of heating is 3.36, exclusive of well pumping energy.

Book excerpt: Results of a study to determine the technical, economic, and environmental feasibility of geothermal district heating for Mammoth Lakes Village, California are reported. The geothermal district heating system selected is technically feasible and will use existing technology in its design and operation. District heating can provide space and water heating energy for typical customers at lower cost than alternative sources of energy. If the district heating system is investor owned, lower costs are realized after five to six years of operation, and if owned by a nonprofit organization, after zero to three years. District heating offers lower costs than alternatives much sooner in time if co-generation and/or DOE participation in system construction are included in the analysis. During a preliminary environmental assessment, no potential adverse environmental impacts could be identified of sufficient consequence to preclude the construction and operation of the proposed district heating system. A follow-on program aimed at implementing district heating in Mammoth is outlined.
