Project for laboratory study for removal of organic sulfur from coal. Quarterly technical progress report
The Gravimelt Process was extended to the desulfurization of ordinary mine-cleaned Kentucky No. 11 coal obtained from the Tennessee Valley Authority. Eight process runs were made resulting in reduction of the sulfur content from a starting 2.7 lbs S/10/sup 6/ Btu to a mean of 0.475 lbs S/10/sup 6/ Btu, (0.95 lbs SO/sub 2//10/sup 6/ Btu) for an average 82% sulfur reduction. The effect of utilization of molten sodium hydroxide alone vs molten mixed potassium and sodium hydroxide was investigated for this coal; sulfur reduction averaged 84% for the mixed melt and 78% for the use of sodium hydroxide alone. A double extraction with sodium hydroxide resulted in a reduction in total sulfur to 0.3 lbs S/10/sup 6/ Btu which is an 89% reduction. In a series of experiments, the melt was reused three times on fresh samples of coal, always giving the same amount of sulfur reduction. Extraction of the desulfurized Kentucky No. 11 coals with an additional dilute sulfuric acid wash reduced the ash content of the coal from 7.9% to a level of 0.3%, thus providing a solid hydrocarbon fuel similar in both ash and sulfur content to a medium grade fuel oil. Multiple experimentation on high …

Safety-analysis report for packaging (SARP) general-purpose heat-source module 750-Watt shipping container
The SARP includes discussions of structural integrity, thermal resistance, radiation shielding and radiological safety, nuclear criticality safety, and quality control. Extensive tests and evaluations were performed to show that the container will function effectively with respect to all required standards and when subjected to normal transportation conditions and the sequence of four hypothetical accident conditions (free drop, puncture, thermal, and water immersion). In addition, a steady state temperature profile and radiation profile were measured using two heat sources that very closely resemble the GPHS. This gave an excellent representation of the GPHS temperature and radiation profile. A nuclear criticality safety analysis determined that all safety requirements are met.

Quality site seasonal report, Tucson Job Corps Center, SFBP (Solar in Federal Buildings Program) 1751, November 1984 through July 1985
The active solar Domestic Hot Water (DHW) system at the Tucson Job Corps Center was designed and constructed as part of the Solar in Federal Buildings Program (SFBP). This retrofitted system is one of eight of the systems in the SFBP selected for quality monitoring. The purpose of this monitoring effort is to document the performance of quality state-of-the-art solar systems in large Federal buildings. The systems are unique prototypes. Design errors and system faults discovered during the monitoring period could not always be corrected. Therefore, the aggregated overall performance is often considerably below what might be expected had similar systems been constructed consecutively with each repetition incorporating corrections and improvements. The solar collector system is installed on a two story dormitory at the Job Corps Center. The solar system preheats hot water for about two hundred students. The solar system provided about 50% of the energy needed for water heating in the winter and nearly 100% of the water heating needs in the summer. There are about 70,000 gallons of water used per month. There are seventy-nine L.O.F. panels or 1659 square feet of collectors (1764 square feet before freeze damage occurred) mounted in two rows on the south …

Quality site seasonal report, Eisenhower Museum, SFBP (Solar in Federal Buildings Program) 4008, March 1985 through September 1985
The active solar Domestic Hot Water (DHW) and space heating system at the Eisenhower Museum was designed and constructed as part of the Solar in Federal Buildings Program (SFBP). This retrofitted system is one of eight of the systems in the SFBP slected for quality monitoring. The purpose of this monitoring effort is to document the performance of quality state-of-the-art solar systems in large federal building applications. These systems are unique prototypes. Design errors and system faults discovered during the monitoring period could not always be corrected. Therefore, the aggregate, overall performance is often considerably below what might be expected had similar systems been constructed consecutively with each repetition incorporating corrections and improvements. The solar system is a retrofit, designed to supply part of the space heating (and reheating for humidity control) load at the museum, located at President Eisenhower's boyhood home in Abilene, Kansas. The small DHW load is also served by the solar system. The museum and adjacent library entertain approximately 200,000 visitors per year, and require controlled temperature and humidity for preservation of artifacts. The summer reheating load for humidity control is comparable to the space heating load in winter. The solar system has 110 US Solar …

Quality site seasonal report, Fort Devens Launderette, SFBP (Solar in Federal Buildings Program) 1751, December 1984 through June 1985
The active solar Domestic Hot Water (DHW) system at the Fort Devens Launderette was designed and constructed as part of the Solar in Federal Buildings Program (SFBP). This retrofitted system was one of eight systems selected for quality monitoring. The purpose of this monitoring effort was to document the performance of quality state-of-the-art solar systems in large federal buildings. The launderette is part of the Post Exchange complex at the Fort Devens Army Post in Fort Devens, Massachusetts. The solar system preheats hot water for the coin operated laundry which has an estimated 25,000 customers per year. There are 108 collector panels comprising the 2563-square foot collector array. Collected solar energy is stored in a 3800-gallon tank. Propylene glycol is used to protect the solar array from freezing. Two immersed heat exchangers provide heat transfer from the propylene glycol to directly heat the DHW supply water in the storage tank. Auxiliary energy is supplied by gas and oil boilers. This solar system can be considered one of a kind and as such is a prototype. The lessons learned from building and operating this system should be used to correct design deficiencies and improve the performance of future solar systems for …
