Geothermal aquaculture project, Real Property System's, Inc., Harney Basin, Oregon( Book )

3 editions published in 1981 in English and held by 6 WorldCat member libraries worldwide

Real Property Systems Inc., (RPS) owns two parcels in the vicinity of Harney Lake, Oregon. One parcel is 120 acres in size, the other is 200 acres. A study concludes that the 200 acre parcel has the greater potential for geothermal development. RPS is interested in an aquaculture operation that produces fresh water prawns, (Macrobrachium rosenbergii) for the market. To supply the heat necessary to maintain the ideal temperature of 82°F desired for these prawns, a geothermal resource having a 150°F temperature or higher, is needed. The best estimate is that 150°F water can be found from a minimum 1090 feet depth to 2625 feet, with no absolute assurances that sufficient quantities of geothermal waters exist without drilling for the same. This study undertakes the preliminary determination of project economics so that a decision can be made whether or not to proceed with exploratory drilling. The study is based on 10 acres of ponds, with a peak requirement of 2500 gpm of 150°F geothermal water
Geothermal heating facilities for Carson Elementary School and Wind River Middle School by Oregon Institute of Technology( Book )

2 editions published in 1982 in English and held by 5 WorldCat member libraries worldwide

Carson Elementary School and Wind River Middle School are located in Carson, Washington, adjacent to the Wind River. Both schools are operated by the Stevenson-Carson School District. Carson Elementary, comprised of 49,000 square feet, was constructed in several phases beginning in 1951. The construction is variable, but is characterized by large expanses of single glass and uninsulated masonry areas. An oil fired steam boiler supplies a variety of terminal equipment. Wind River Middle School was built in 1972 and, as a result, exhibits much greater insulation levels. The 38,000 square foot structure is heated entirely by an electric resistance terminal reheat system. Carson Hot Springs Resort, located approximately one half mile from the schools, exhibits temperatures of 124°F. In addition, geological work is in progress to better define the local geothermal resource. The feasibility of geothermal use at the school for space heating purposes is examined
Basin View Geothermal Heating District, Klamath Falls, Oregon : conceptual design and economic feasibility study report( Book )

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

2 editions published in 1981 in English and held by 3 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
Marketing the Klamath Falls geothermal district heating system by Kevin D Rafferty( Book )

3 editions published in 1993 in English and held by 1 WorldCat member library 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

Vertical pump turbine oil environmental evaluation by Gene Culver( )

2 editions published between 1991 and 1996 in English and held by 0 WorldCat member libraries worldwide

This report examines the capital and operating costs for fossil fuel-fired peak heating systems in geothermally (direct use) heated greenhouses. Issues covered include equipment capital costs, fuel requirements, maintenance and operating costs, system control and integration into conventional hot water greenhouse heating systems. Annual costs per square foot of greenhouse floor area are developed for three climates: Helena, MT; Klamath Falls, OR and San Bernardino, CA, for both boiler and individual unit heater peaking systems. In most applications, peaking systems sized for 60% of the peak load are able to satisfy over 95% of the annual heating requirements and cost less than $0.15 per square foot per year to operate. The propane-fired boiler system has the least cost of operation in all but Helena, MT climate

Direct use geothermal applications for brazed plate heat exchangers( )

2 editions published in 1993 in English and held by 0 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 H₂S 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 H₂S 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° or greater. Size limitations restrict applications to 100 gpm and/or 200 ft² heat transfer surface area
Selected cost considerations for geothermal district heating in existing single-family residential areas( )

3 editions published between 1993 and 1996 in English and held by 0 WorldCat member libraries worldwide

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 business districts, other frequently overlooked factors may compensate for load density. In particular, costs for distribution system installation can be substantially lower in some residential areas due to a variety of factors. This reduced development cost may partially compensate for the reduced revenue resulting from low-load density. This report examines cost associated with the overall design of the system (direct or indirect system design), distribution piping installation, and customer branch lines. It concludes with a comparison of the costs for system development and the revenue from an example residential area
Geothermal space and water heating facilities : Schooler Apartments, Klamath Falls, Oregon by Oregon Institute of Technology( )

3 editions published between 1981 and 1982 in English and held by 0 WorldCat member libraries worldwide

Utilizing the warm well water for a geothermal greenhouse heating system is highly economically feasible. This is based on using the 88°F water from Anderson Well No. 1 to heat greenhouses totaling approximately 10.6 acres. The additional investment of $640,000 above the cost for a conventional electric boiler system shows a rate of return of 48.3% on a 20 year life cycle analysis. The simple payback is 3 years. The 88°F well water is not warm enough for prawn (Macrobrachium rosenbergii) aquaculture, since water flow requirements are excessive to maintain the desired 80°F pond temperature. However, the water is warm enough to maintain a 60°F pond temperature for trout farming. Trout farming using the 88°F well water directly is probably not economically feasible due to high electrical pumping cost (34,626 per year) for the seven 1/2 acre ponds that could be heated. Trout farming using the 75°F effluent water from the 10.6 acre greenhouse to heat four 1/2 acre ponds may be economically feasible since the water booster pumping cost is low $1189 per year
