Energy related applications of elementary particle physics (open access)

Energy related applications of elementary particle physics

The current research position is summarized, and what could be done in the future to clarify issues which were opened up by the research is indicated. Following on the discussion of the viability of catalyzed fusion, there is presented along with the key experimental results, a short account of the physics surrounding the subject. This is followed by a discussion of key research topics addressed. In consequence of the progress made, it appears that the feasibility of a small-scale fusion based on catalyzed reactions rests on either the remote chance that a yet undiscovered ultraheavy negatively charged elementary particle exists in Nature, or on the possible technical realization of a system based on muon-catalyzed fusion (MuCF) in high-density degenerate hydrogen plasma (density 1000 LHD, temperature O(100 eV)). The lattter is considered to have practical promise.

Pulsed Electron Beam Precharger (open access)

Pulsed Electron Beam Precharger

Quarter Eight of the Pulsed Electron Precharging project was principally devoted to the operation of the E-beam precharger in the pulsed anode mode. We shall first briefly review the motivation for carrying out this project and the experimental approach used. The combustion of low sulfur coal for the purpose of generating electric energy in power plants results in the production of a flue gas containing very high resistivity fly ash. This fly ash is not easily collected by conventional electrostatic precipitators due to the large electric potential difference which develops across the layer of fly ash on the collector plate. If this layer of collected material is allowed to reach a thickness as great as is normally desirable before rapping'' the plates, then the collected fly ash is subject to re-entrainment into the flue gas stream due to back-corona. The back-corona corona problem is described more fully in the next section of this report. This re-entrainment problem can be eliminated through reduction of the voltage applied across the high voltage wires and the grounded plates of the electrostatic precipitator. This is not a good solution to the problem since the charging capability and collection efficiency of the precipitator system are …

sup 31 P NMR analysis of coal moieties bearing -OH, -NH, and -SH functions (open access)

sup 31 P NMR analysis of coal moieties bearing -OH, -NH, and -SH functions

NMR reagents for the speciation and quantitation of labile-hydrogen functional groups and sulfur groups in coal ligands have been synthesized and evaluated. These reagents, which contain the NMR-active nuclei {sup 31}p, {sup 119}Sn or {sup 195}pt, were designed to possess improved chemical shift resolution over reagents reported in the literature. Our efforts were successful in the case of the new {sup 31}p and {sup 119}Sn reagents we developed, but the {sup 195}pt work on sulfur groups was only partially successful in as much as the grant came to a close and was not renewed. Our success with {sup 31}P and {sup 119}Sn NMR reagents came to the attention of Amoco and they have recently expressed interest in further supporting that work. A further measure of the success of our efforts can be seen in the nine publications supported by this grant which are cited in the reference list.

The demonstration of an advanced cyclone coal combustor, with internal sulfur, nitrogen, and ash control for the conversion of a 23 MMBtu/hour oil fired boiler to pulverized coal

The project objective was to demonstrate a technology which can be used to retrofit oil/gas designed boilers, and conventional pulverized coal fired boilers to direct coal firing, by using a patented sir cooled coal combustor that is attached in place of oil/gas/coal burners. A significant part of the test effort was devoted to resolving operational issues related to uniform coal feeding, efficient combustion under very fuel rich conditions, maintenance of continuous slag flow and removal from the combustor, development of proper air cooling operating procedures, and determining component materials durability. The second major focus of the test effort was on environmental control, especially control of SO{sub 2} emissions. By using staged combustion, the NO{sub x} emissions were reduced by around 3/4 to 184 ppmv, with further reductions to 160 ppmv in the stack particulate scrubber. By injection of calcium based sorbents into the combustor, stack SO{sub 2} emissions were reduced by a maximum of of 58%. (VC)

Inventor and innovator pilot project program (open access)

Inventor and innovator pilot project program

The Commission for Economic Development in Orem (CEDO) has completed its pilot project: setting up an inventor organization, providing knowledgeable speakers for monthly meetings, and trying to assess and meet the needs of that group. Utah Valley Community College provided space for monthly inventor meetings. It was decided that the monthly meetings would be held as two-hour mini seminar sessions with qualified speakers. The college provided continuing education units free for attendance at the meetings. Results of two surveys of the group were analyzed. A meeting was held between CEDO and the college's Dean of the School of Business where it was decided that the group should be continued. The college will continue providing space for the monthly meetings and assisting with the attraction of additional qualified speakers. CEDO will continue to locate speakers, put on the monthly meetings publish the monthly newsletter and provide information and assistance for the group. It has been determined by CEDO that having a group'' with monthly speakers is only a pacification of the needs of inventors and innovators. This group is in dire need of specialized inventor ASSISTANCE on a no-cost or low-cost basis.

Molecular biological enhancement of coal desulfurization: Cloning and expression of the sulfoxide/sulfone/sulfonate/sulfate genes in Pseudomonads and Thiobacillae (open access)

Molecular biological enhancement of coal desulfurization: Cloning and expression of the sulfoxide/sulfone/sulfonate/sulfate genes in Pseudomonads and Thiobacillae

The DbtS{sup +} phenotype is defined as the selective ability to oxidize the sulfur in dibenzothiophene (DBT) successively to dibenzothiophene-5-oxide, dibenzosulfone, and, finally, either o, o'-biphenol or monohydroxybiphenyl. By using a fluorescent assay, many Pseudomonas putida isolates having a DbtS{sup +} phenotype have been obtained. The ability of the isolates to generate o, o'-biphenol was confirmed with HPLC shortly after the time of isolation. The broad-host-range plasmid, R68.45, was introduced from P. putida PRS 2003 into many soil isolates. The plasmid was able to mobilize the determinants for the DbtS{sup +} phenotype. Accordingly, R68.45 and the determinants of the phenotype could be transferred simultaneously form soil isolates to P. aeruginosa 27853. The DbtS{sup +} phenotype in the isolates and in P. aeruginosa 27853 has proven to be unstable. Whether the instability is genetic, physiological, some combination of these two, or is founded on some other phenomenon is not known. Fresh Gram-positive isolates with the DbtS{sup +} phenotype have been isolated using the sulfur bioavailability assay. The DbtS{sup +} phenotype in these isolates appears to be stable. The product of desulfurization of DBT of dibenzosulfone is monohydroxybiphenyl. The nature of the endproduct has been confirmed by HPLC, colorimetry, GC/mass spectroscopy, and …

NO{sub x} Abatement Pilot Plant 90-day test results report (open access)

NO{sub x} Abatement Pilot Plant 90-day test results report

High-level radioactive liquid wastes produced during nuclear fuel reprocessing at the Idaho Chemical Processing Plant are calcined in the New Waste Calcining Facility (NWCF) to provide both volume reduction and a more stable waste form. Because a large component of the HLW is nitric acid, high levels of oxides of nitrogen (NO{sub x}) are produced in the process and discharged to the environment via the calciner off-gas. The NO{sub x} abatement program is required by the new Fuel Processing Restoration (FPR) project permit to construct to reduce NO{sub x} emissions from the NWCF. Extensive research and development has indicated that the selective catalytic reduction (SCR) process is the most promising technology for treating the NWCF off-gas. Pilot plant tests were performed to determine the compatibility of the SCR process with actual NWCF off-gas. Test results indicate that the SCR process is a viable method for abating the NO{sub x} from the NWCF off-gas. Reduction efficiencies over 95% can be obtained, with minimal amounts of ammonia slip, provided favorable operating conditions exist. Two reactors operated with series flow will provide optimum reduction capabilities. Typical operation should be performed with a first reactor stage gas space velocity of 20,000 hr{sup {minus}1} and …

Z degree yields hadrons in SDC (open access)

Z degree yields hadrons in SDC

We report on a study of hadronic Z{degrees} decays at high P{sub t}(P{sub t}>500 GeV/c), at 40 TeV CM energy. Our goal here is to understand the effects of the kinematics of Z{degrees} decay, especially the Lorentz boost, on detection issues. We used an ISAJET sample of Drell Yan events, requiring the Z{degrees} to have pseudorapidity ({eta}) in (-1.5,1.5) and P{sub t}>500 GeV/c. ISAJET forces the Z{degrees} to decay to two primary partons, which then cascade by gluon and quark emission to stable hadrons. We excluded Z{degrees} {yields} {nu}{bar {nu}} decays. In about 10% of the hadronic decays, significant energy is lost due to neutrino emission from heavy quarks, so that the hadronic mass is significantly less than the Z{degrees} mass generated; these events were not explicitly removed. We treated muons like other hadrons, assuming that high P{sub t} muons could be identified and corrected for. For this study we retained only the stable daughter particles in Z{degrees} decay, labelled according to their parton parentage ( Jet 1 or 2''). We ignored the particles from the underlying event and from other final state jets. (These contributions, along with other non-Z{degrees} noise'', can be explicitly added back for relevant studies.) Finally, …

Coal desulfurization in a rotary kiln combustor (open access)

Coal desulfurization in a rotary kiln combustor

Several issues that could have an impact on the capability to burn anthracite culm in a rotary bed boiler were identified; specifically, questions were raised concerning the specifications of the anthracite culm itself and some relating to the equipment. The anthracite culm delivered was wet, (with more than 10 percent moisture), and coarser than feed material for fluidized boilers. It was felt that using finer fuel, ensuring that it is largely dry, would aid the combustion of anthracite culm. It also appeared that if provisions were made for more efficient internal and external recycle of ash, this would also enhance the combustion of this fuel. Accordingly, the decision was made to conduct an additional campaign of tests that would incorporate these changes. The tests, conducted on July 15 and 16, 1991, involved an anthracite culm that was, in fact, obtained from a fluidized bed a heating value of 3,000 Btu/lb and came with a top size of 1/4-inch. Despite these changes, sustained combustion could not be achieved without the use of large quantities of supplemental fuel. Based on these tests, we tend to conclude that the rotary kiln is ill suited for the combustion of hard-to-burn, low-grade solid fuels like …

Conversion electrons in the SDC (open access)

Conversion electrons in the SDC

We summarize a preliminary analysis of the rates for conversion electrons in the SDC detector, relative to other interesting sources of prompt electrons. We have used Papageno V3.30, and other available NLO calculations to estimate inclusive rates in the central region ({eta} less than 2.0), and we have cross checked these using CDF data at 1.8 TeV. We have considered three sources of isolated'' electrons, namely inclusive W/Z production; top quark (Mt=140); and QCD prompt photon production, followed by conversion in 10% XO. This value approximates the inner silicon detector at SDC. Additional conversions will occur in the outer tracking chamber, but the trigger and track reconstruction efficiency will be lower. We have also considered nonisolated'' leptons coming from inclusive bottom production, photon conversions resulting from {pi}{sup 0},{eta} production in jets, and high pt hadrons faking electrons.
