Abstract
The Torbett-Hutchings-Smith Memorial Hospital geothermal heating project, which is one of nineteen direct-use geothermal projects funded principally by DOE, is documented. The five-year project encompassed a broad range of technical, institutional, and economic activities including: [...]Abstract
The first buried asbestos-cement (Transite) pipeline used in high temperature (approximately 300/sup 0/F) service for transport of geothermal fluids was installed in the fall of 1975, and has seen 1/sup 1///sub 2/ years of service. The line is 4000 ft long, between the deep geothermal [...]Abstract
The results of a materials survey for the Baca 50 MW(e) single flash geothermal plant in the Valles Caldera of New Mexico are presented. From the design documents provided, materials proposed for use in contact with the plant atmosphere, the two-phase geofluid, the separated steam, [...]Abstract
A survey was conducted to determine operation and maintenance (O and M)-related materials needs in geothermal power plants and to identify future research and development to address these needs. A total of 44 questionnaires was mailed to geothermal plant operators and industry consultants. [...]Abstract
Information on the geothermal resources of the San Luis Valley, Colorado, has been gathered and reviewed and a preliminary, quantitative assessment of the magnitude and quality of resources present was carried out. Complete process designs were developed for the processes of producing [...]Abstract
A preliminary study of the feasibility of using existing drinking water supply systems to provide hot water for heating purposes to a typical 140-home subdivision has been undertaken. This preliminary study has centered on (i) types of municipal water system designs and effects of [...]Abstract
In the past, district heating (geothermal or conventionally fueled) has not been widely applied to the single-family residential sector. Low-heat load density is the commonly cited reason for this. Although it`s true that load density in these areas is much lower than for downtown [...]Abstract
Asbestos-cement (Transite) pipe was installed at the Raft River Geothermal Area in the fall of 1975 and has been used extensively since. The pipe is used to transfer water from the well sites to the testing areas, reserve pits, and reinjection wells. The pipeline was designed to transport [...]Abstract
Two options for supplying geothermal energy to the Veterans Administration Medical Center (VAMC) at Marlin, Texas were compared. One option is to drill a new production well on the VAMC property, and the other is to construct a 6900-ft pipeline from an existing geothermal well to [...]Abstract
Four parameters are used to define a particular pipe: inside diameter, wall thickness, material, and ends. The factors influencing pipe selection are limited to fluid pressure, temperature, chemistry, flow rate, and cost. Other pipe parameters and factors that influence pipe selection [...]
