Design requirement for dual air supplies to melter borescope

Description: The long term survivability and usefulness of the melter surface viewing borescopes would be greatly increased if a method of remote lense cleaning was available. The two units to be installed on the DWPF melter will incorporate air cooling and lense purging into their design. At present a single air supply line would serve both needs. Separating the two air services will allow the introduction of water or steam into the purge service. Tests on the prototype borescope at ETF have shown this to … more

Use of oxides in thermochemical water-splitting cycles for solar heat sources: copper oxides

Description: Cycles using solid oxide decomposition as the high temperature step may have advantages for coupling with a solar furnace. The CuO-Cu/sub 2/O cycle consists of the following steps: 2 CuO = Cu/sub 2/O + 1/2 O/sub 2/ (1300/sup 0/K); I/sub 2/ + Cu/sub 2/O + Mg(OH)/sub 2/ = 2 CuO + Mg I/sub 2/ + H/sub 2/O (448/sup 0/K); MgI/sub 2/ + H/sub 2/O = MgO + 2 HI(g); 2 HI = H/sub 2/ + I/sub 2/; and MgO + H/sub 2/O = Mg(OH)/sub 2/. The stages in the second reaction are discussed. The oxidation of CuI to CuO… more

High-frequency furnace. Technical progress report. Eighth quarterly report for period ending September 30, 1983

Description: An important phase of silicon solar cell production via ingot technology is the conversion of polycrystalline silicon to the single-crystal, ingot form that is required for wafering. In the current art such ingots are produced either by pulling from the melt or by various crucible growth techniques. A characteristic of all of these methods, which use bulk melting, is that a refractory crucible is required to hold the molten charge. This imposes the disadvantages that the silicon is always conta… more

Energy and materials flows in the iron and steel industry

Description: Past energy-consumption trends and future energy-conservation opportunities are investigated for the nation's iron and steel industry. It is estimated that, in 1980, the industry directly consumed approximately 2.46 x 10/sup 15/ Btu of energy (roughly 3% of total US energy consumption) to produce 111 million tons of raw steel and to ship 84 million tons of steel products. Direct plus indirect consumption is estimated to be about 3.1 x 10/sup 15/ Btu. Of the set of conservation technologies iden… more

High-temperature waste-heat-stream selection and characterization

Description: Four types of industrial high-temperature, corrosive waste heat streams are selected that could yield significant energy savings if improved heat recovery systems were available. These waste heat streams are the flue gases from steel soaking pits, steel reheat furnaces, aluminum remelt furnaces, and glass melting furnaces. Available information on the temperature, pressure, flow, and composition of these flue gases is given. Also reviewed are analyses of corrosion products and fouling deposits … more

State-of-the-art of furnace recuperation in the primary metals industry: technical briefing report

Description: Existing and emerging recuperator technology is identified, as well as the technical and economic issues in applying such technology. An overview of recuperation and its relevance to the primary metals industry is presented. Design considerations, equipment, and energy and cost savings of five recuperator applications in the primary metals industry are examined. Three applications include a case history of a recent recuperator installation. A cost engineering analysis of recuperator technology … more

Field testing of an automated wood-combustion system and development of business plan for commercialization of production. Final report for period ending August 1, 1982

Description: A tunnel burner for burning wood chips has been installed and tested at a school building in Durham, NC. The test revealed many problems which did not exist while testing a prototype in laboratories. Controls were found to work reliably. A business plan was developed and is appended. (LEW)

Savannah River Plant defense waste vitrification studies during FY 1982. Summary report

Description: Five major melter runs were completed during FY 1982 on the Pilot-Scale Ceramic Melter (PSCM). Over 41,000 L of feed were processed by the PSCM, producing approx. 21,000 kg of glass. The design basis reference capacity of approx. 39 kg/h-m/sup 2/ was met or exceeded in all the melter runs. Off-gas characterization was emphasized during this fiscal year. Entrainment of feed material is the largest contributor to the mass of particulate leaving the melter, averaging 0.2 wt% of the incoming feed o… more

Investigate the effectivness of calcium-treated coals in the capture of sulfur gases generated in staged fired combustors. Third quarterly technical progress report, May 1-July 31, 1983

Description: In this quarter's work, a new procedure was developed to add calcium to pulverized coal. The method has been found to increase the calcium content of bituminous coal to 12% calcium by weight, which corresponds to a Ca/S ratio of greater than 2. Progress was also made on the combustion test facility this quarter. A new modification of the low-flow coal feeder has made that system steady and reliable. With the furnace wired and plumbed, and the other subsystems complete, the facility is almo… more

Off-gas characteristics of defense waste vitrification using liquid-fed Joule-heated ceramic melters

Description: Off-gas and effluent characterization studies have been established as part of a PNL Liquid-Fed Ceramic Melter development program supporting the Savannah River Laboratory Defense Waste Processing Facility (SRL-DWPF). The objectives of these studies were to characterize the gaseous and airborne emission properties of liquid-fed joule-heated melters as a function of melter operational parameters and feed composition. All areas of off-gas interest and concern including effluent characterization, … more

Evaluation of a processing technique for immobilization of low-level waste

Description: A commercially available joule-heated glass furnace system is currently being evaluated at Mound as a means of processing low-level radioactive waste typically found in light water reactor facilities. This evaluation has been primarily concerned with determining the effectiveness of the processing technique in the areas of volume reduction and immobilization. The first phase of the evaluation consisted of a series of nonradioactive experiments to determine the combustion efficiency of the furna… more

Design and performance of feed delivery systems for simulated radioactive waste slurries

Description: Processes for vitrifying simulated high-level radioactive waste have been developed at the Pacific Northwest Laboratory (PNL) over the last several years. Paralleling this effort, several feed systems used to deliver the simulated waste slurry to the melter have been tested. Because there had been little industrial experience in delivering abrasive slurries at feed rates of less than 10 L/min, early experience helped direct the design of more-dependable systems. Also, as feed delivery requireme… more
