Data acquisition for low-temperature geothermal well tests and long-term monitoring. Final report( )

2 editions published in 1992 in English and held by 8 WorldCat member libraries worldwide

Groundwater monitoring is an essential part of the development of a low-temperature geothermal field for production and injection wells. State water resource and environmental departments are requiring both geothermal well testing and long-term monitoring as a part of the permitting process for geothermal developments. This report covers water-level measurement methods, instruments used for well testing, geochemical sampling, examples of data acquisition and regulatory mandates on groundwater monitoring
Direct use geothermal applications for brazed plate heat exchangers( )

2 editions published in 1993 in English and held by 8 WorldCat member libraries worldwide

Brazed plate heat exchanger were placed in three geothermal fluids (Klamath Falls, OR; Boise, ID; and Pagosa Springs, CO) in order to determine the effect of H[sub 2]S on braze material. Based on subsequent analysis, it appears that the rate of corrosion of the braze material is much slower than corrosion of copper tube materials in the same fluids. Minimum expected life of the heat exchangers based on these corrosion rates is reported to be 12 years in fluids of less than 1 ppm H[sub 2]S and 10 years in fluids of less than 5 ppm. Based on these expected lives, and using a 3% inflation rate and 8% discount rate, brazed plate heat exchangers are a clear economic choice in which the capital cost is 50% or less of the cost of a plate and frame heat exchanger for the same duty. Due to their single pass design, brazed plate heat exchangers are generally limited to approach temperatures of 10[degree] or greater. Size limitations restrict applications to 100 gpm and/or 200 ft[sup 2] heat transfer surface area
Pilot fruit drier for Los Azufres geothermal field, Michoacan, Mexico( )

2 editions published in 1993 in English and held by 8 WorldCat member libraries worldwide

Comision Federal de Electricidad (CFE) has a Division in charge of the exploration of a geothermal reservoir located in Los Azufres, State of Michoacan. At present, CFE is only using the steam of the wells and rejecting the hot water that comes off associated with the steam. Based on a trip to the Los Azufres geothermal field in December of 1992, a design for a pilot geothermal fruit drier was undertaken for CFE. The details of the geothermal field and the local fruit production are detailed

Marketing the Klamath Falls Geothermal District Heating system( )

2 editions published in 1993 in English and held by 7 WorldCat member libraries worldwide

The new marketing strategy for the Klamath Falls system has concentrated on offering the customer an attractive and easy to understand rate structure, reduced retrofit cost and complexity for his building along with an attractive package of financing and tax credits. Initial retrofit costs and life-cycle cost analysis have been conducted on 22 buildings to date. For some, the retrofit costs are simply too high for the conversion to make sense at current geothermal rates. For many, however, the prospects are good. At this writing, two new customers are now connected and operating with 5 to 8 more buildings committed to connect this construction season after line extensions are completed. This represents nearly a 60% increase in the number of buildings connected to the system and a 40% increase in system revenue

District heating system, College Industrial Park, Klamath Falls, Oregon( )

1 edition published in 1981 in English and held by 4 WorldCat member libraries worldwide

The College Industrial Park (CIP) is located to the northwest of the Oregon Institute of Technology (OIT) campus. Waste water from the OIT campus geothermal heating system flows through an open ditch to the south of the Park. Being aware of this, city personnel have requested the Geo-Heat Center design a distribution network for the Park to eventually utilize an estimated 600 GPM of the 130°F waste water. Geothermal water from each campus building is discharged into storm drains which also collect surface run off from parking lots, roofs and grounds. Waste water temperatures are generally between 120°F and 130°F, however, it may drop as low as 90°F when mixing occurs with large amounts of surface run off. Peak heating load requirements for the OIT campus are estimated to be 17.8 x 10⁶ Btu/hour for 567,000 square feet of space. Peak flow rate of geothermal fluid to satisfy this load is then 593 GPM based on a net 60°F temperature differential. Three wells are available to supply the necessary flow. A Lithium-Bromide Absorption Chiller (185 ton) was installed in 1980 to provide space cooling. The chiller requires a constant flow rate of 550 GPM and discharges 170°F water to the storm drains during summer months
Basin View Geothermal Heating District, Klamath Falls, Oregon conceptual design and economic-feasibility study report( )

1 edition published in 1981 in English and held by 4 WorldCat member libraries worldwide

The findings of a feasibility study performed for Basin View Heating District in Klamath Falls, Oregon are reported. The purpose of the study is to determine the physical, economic, and political feasibility of establishing a geothermal heating district to provide space heat to housing units in the Basin View Development of Klamath Falls. Of the several systems considered, all are physically feasible. The project is politically feasible if the owner compiles with governmental requirements. Economic feasibility is based on considerations of money value rates, tax rates and expected rates of return, which are dependent on government and money markets. For analysis a money value rate of 21% and an owner's marginal tax rate of 35% were adopted

Geothermal aquaculture a guide to freshwater prawn culture( )

1 edition published in 1980 in English and held by 4 WorldCat member libraries worldwide

Biological data of the Malaysian prawn, Macrobrachium rosenbergii, are summarized. A history on its rearing techniques is given, but through the use of geothermal water or industrial warm water effluent, its range can be expanded. The use of wasted geothermal water at the Oregon Institute of Technology for prawn ponds is noted. Pond management and design; the hatchery design and function for larval culture; and geothermal applications (legal aspects and constraints) are discussed. (MCW)
District-heating system, La Grande, Oregon( )

1 edition published in 1982 in English and held by 4 WorldCat member libraries worldwide

The area suggested for district heating feasibility study encompassed slightly over 400 acres extending north and south from the geographic center of the city. This district was subdivided into 8 areas, which include the Grande Ronde Hospital, Eastern Oregon State College, La Grande school district, one institutional area, one commercial area and three residential areas. Basic space heating loads developed for the various areas after a survey by county personnel and computation using a computer program form the basis for this economic feasibility study
