Burns Burns Burns can result from everyday things and activities in your home. The most common causes of burns are from scalds (steam, hot bath water, hot drinks and foods), fire, chemicals, electricity and overexposure to the sun. Some burns may be more serious than others. The severity of the burn is based on the depth of the burn. First degree burns are the least severe, and third degree burns are the most severe. Call 911 or seek medical attention if you are unsure of how severe your burn is. All burns are susceptible to tetanus (lockjaw). Get a tetanus shot every 10 years. If your last shot was 5 years ago, talk to your doctor - you may need a booster shot. Causes of Burns: Scalds Scalding injuries and burns are caused by hot tap water, hot beverages and food, and steam.

Sun tanning/burning Sun tanning/burning Name: Richardo Cossyleon Location: N/A Country: N/A Date: N/A Question: Why doesn't the sun affect or burn people with dark pigment in their skin? Replies: Good question! The pigment, melanin, is more toward the surface of the upper skin layer and absorbs ultraviolet rays from the Sun or artificial sources. This absorption protects the lower layers from damage and inflammation (burning). A very dark skinned person may have over a 1000X the protection from UV compared to a fair skinned person. Fair skinned people should use sun-block lotions especially early in the warm season AND keep exposure to the sun, particularly at midday, to less than 30 min. Even if a person gets a good tan, the sun's UV will age the skin over time. It will get wrinkled and develop age lines, etc. after many years of exposure. Moderation is the key!

Wood would burn  

Science Journals Connector (OSTI)

Absract In view of the world-wide problem of energy sustainability and greenhouse gas production (carbon dioxide), it is timely to review the issues involved in generating heat and power from all fuels and especially new (to the UK) solid fuels, including high moisture fuels such as wood, SRF, oil shale, tar sands and brown coal, which will become major international fuels as oil and gas become depleted. The combustion properties of some of these materials are significantly different from traditional coal, oil and gas fuels, however the technology proposed herein is also applicable to these conventional fuels. This paper presents some innovative combustion system options and the associated technical factors that must be considered for their implementation. For clarity of understanding, the novel concepts will be largely presented in terms of a currently developing solid fuel market; biomass wood chips. One of the most important characteristics of many solid fuels to be used in the future (including oil shale and brown coal) is their high moisture content of up to 60%. This could be removed by utilising low grade waste heat that is widely available in industry to dry the fuel and thus reduce transport costs. Burning such dried wood for power generation also increases the energy available from combustion and thus acts as a thermal transformer by upgrading the low grade heat to heat available at combustion temperatures. The alternative approach presented here is to recover the latent heat by condensing the extrinsic moisture and the water formed during combustion. For atmospheric combustion, the temperature of the condensed combustion products is below the dew point at about 5565C and is only suitable for recovery in an efficient district heating system. However, in order to generate power from the latent heat, the condensation temperature must be increased to the level where the heat can be used in the thermodynamic power cycle. This can be achieved by increasing the combustion pressure to above 80bar, resulting in the recovered latent heat being available at more than 200C. It can then be used to increase the cycle efficiency by about 15% by pre-heating the boiler water and/or combustion air etc. A further advantage is that the high pressure of the combustion gases also reduces the superheater tube stress since it can balance the steam pressure. The key advantage of this high pressure flue gas is that it is above the pressure at which carbon dioxide condenses to a liquid or supercritical gas at atmospheric temperature. Thus when used with oxy-fuel combustion, the carbon dioxide flue gas from which the moisture has been condensed can be cooled to atmospheric temperature and the supercritical CO2 can be fed directly into the pipes leading to the sequestration site. An important consideration of these strategies is to ensure that non-condensable gases in the exhaust, including oxygen and nitrogen, do not adversely affect the condensation processes. When oxy-fuel combustion is used, the flame temperature must be moderated by a cool diluent. Recycled carbon dioxide is often proposed for this duty. However, since the latent heat is recovered, the moisture or even additional water can fulfil this role. This latter option may be advantageous since it is more efficient to pump wood chip fuel in water into the high pressure zone rather than feed solid wood particles. Surplus water can be simply drained and the wet wood chips are a good fuel when the latent heat of the moisture in the fuel gases is recovered into the power cycle. Bearing in mind that it is much more efficient to pump a liquid to high pressure than to compress the same material as a gas, indicates that cryogenic oxygen is a suitable material to use for an efficient power station that generates energy from biomass (or other fuels such as coal etc). Finally, combustion of the hydrogen from the watergas reaction with oxygen allows the steam temperature in the turbine to be increased to the gas-turbine engine range of 10001400C an

Biomass burning and global change  

Science Journals Connector (OSTI)

The burning of living and dead biomass including forests savanna grasslands and agricultural wastes is much more widespread and extensive than previously believed and may consume as much as 8700 teragrams of dry biomass matter per year. The burning of this much biomass releases about 3940 teragrams of total carbon or about 3550 teragrams of carbon in the form of CO2 which is about 40% of the total global annual production of CO2. Biomass burning may also produce about 32% of the worlds annual production of CO 24% of the nonmethane hydrocarbons 20% of the oxides of nitrogen and biomass burn combustion products may be responsible for producing about 38% of the ozone in the troposphere. Biomass burning has increased with time and today is overwhelmingly human?initiated.

Actinide Burning in CANDU Reactors  

SciTech Connect (OSTI)

Actinide burning in CANDU reactors has been studied as a method of reducing the actinide content of spent nuclear fuel from light water reactors, and thereby decreasing the associated long term decay heat load. In this work simulations were performed of actinides mixed with natural uranium to form a mixed oxide (MOX) fuel, and also mixed with silicon carbide to form an inert matrix (IMF) fuel. Both of these fuels were taken to a higher burnup than has previously been studied. The total transuranic element destruction calculated was 40% for the MOX fuel and 71% for the IMF. (authors)

Pollution by cereal waste burning in Spain  

Science Journals Connector (OSTI)

In this paper, the amount of cereal waste burned in Spain, which represents the most important source of biomass burning in this country, is estimated. During the period between 1980 and 1998, an average mass of 8 Tg of cereal waste was burned annually, with remaining 1 Tg of ash on the cereal fields after combustion. By using emission factors previously calculated by Ortiz de Zrate et al. [Ortiz de Zrate, I., Ezcurra, A., Lacaux, J.P., Van Dihn, P., 2000. Emission factor estimates of cereal waste burning in Spain. Atmos. Environ. 34, 31833193.], it is deduced that pollutant emissions linked to cereal waste-burning process reach values of 11 Tg CO2, 80 Gg of TPM and 23 Gg of \\{NOx\\} year?1 during the cereal-burning period. These emissions represent 46% of total CO2 and 23% \\{NOx\\} emitted in Spain during the burning period that lasts 1 month after harvesting. Therefore, the relative importance of cereal waste burning as pollutant source in Spain almost during fire period becomes evident. Finally, our study allows to deduce that the production of 1 kg of cereal crop implies that 410 g of carbon and 3.3 g of nitrogen are going to be introduced into the atmosphere by this pollutant process. We estimate a total gaseous emission of 3.3 Tg of C and 25 Gg N as different pollutants by cereal waste burning.

Uniform-burning matrix burner  

DOE Patents [OSTI]

Computer simulation was used in the development of an inward-burning, radial matrix gas burner and heat pipe heat exchanger. The burner and exchanger can be used to heat a Stirling engine on cloudy days when a solar dish, the normal source of heat, cannot be used. Geometrical requirements of the application forced the use of the inward burning approach, which presents difficulty in achieving a good flow distribution and air/fuel mixing. The present invention solved the problem by providing a plenum with just the right properties, which include good flow distribution and good air/fuel mixing with minimum residence time. CFD simulations were also used to help design the primary heat exchanger needed for this application which includes a plurality of pins emanating from the heat pipe. The system uses multiple inlet ports, an extended distance from the fuel inlet to the burner matrix, flow divider vanes, and a ring-shaped, porous grid to obtain a high-temperature uniform-heat radial burner. Ideal applications include dish/Stirling engines, steam reforming of hydrocarbons, glass working, and any process requiring high temperature heating of the outside surface of a cylindrical surface.

Treatment of a severe alkali burn  

Science Journals Connector (OSTI)

The case history of a 20-year-old male patient who sustained an 85 per cent total body surface area alkali burn to his skin, after falling into a caustic lime pit, is reported. Considerable problems regarding the correct estimate of burn wound depth, predominant location of the deepest burn on the posterior half of the body, appropriate wound coverage, and lack of sufficient skin graft donor sites required a complex treatment plan. Excisions to fascia and intradermal debridement were required to achieve an appropriate bed for wound closure. Five per cent mafenide acetate solution (Sulfamylon) was applied to prevent burn wound sepsis. Human allografts and Biobrane were used extensively to achieve temporary wound closure, to provide mechanical protection of freshly autografted wounds, and to prevent desiccation following application of cultured epidermal autografts on to debrided wounds and split thickness skin grafted donor sites. The case illustrates a number of problems associated with the evaluation and treatment of patients suffering severe alkali burns, and demonstrates the implementation of both established and evolving technologies in the management of these injuries.

Polycyclic aromatic hydrocarbons (PAHs) in burning and non-burning coal waste piles  

Science Journals Connector (OSTI)

The coal waste material that results from Douro Coalfield exploitation was analyzed by gas chromatography with mass spectrometry (GCMS) for the identification and quantification of the 16 polycyclic aromatic hydrocarbons (PAHs), defined as priority pollutants. It is expected that the organic fraction of the coal waste material contains \\{PAHs\\} from petrogenic origin, and also from pyrolytic origin in burning coal waste piles. The results demonstrate some similarity in the studied samples, being phenanthrene the most abundant PAH followed by fluoranthene and pyrene. A petrogenic contribution of \\{PAHs\\} in unburned samples and a mixture of \\{PAHs\\} from petrogenic and pyrolytic sources in the burning/burnt samples were identified. The lowest values of the sum of the 16 priority \\{PAHs\\} found in burning/burnt samples and the depletion LMW \\{PAHs\\} and greater abundance of HMW \\{PAHs\\} from the unburned coal waste material relatively to the burning/burnt material demonstrate the thermal transformation attributed to the burning process. The potential environmental impact associated with the coal waste piles are related with the release of petrogenic and pyrolytic \\{PAHs\\} in particulate and gaseous forms to soils, sediments, groundwater, surface water, and biodiversity.

High Pressure Burn Rate Measurements on an Ammonium Perchlorate Propellant  

SciTech Connect (OSTI)

High pressure deflagration rate measurements of a unique ammonium perchlorate (AP) based propellant are required to design the base burn motor for a Raytheon weapon system. The results of these deflagration rate measurements will be key in assessing safety and performance of the system. In particular, the system may experience transient pressures on the order of 100's of MPa (10's kPSI). Previous studies on similar AP based materials demonstrate that low pressure (e.g. P < 10 MPa or 1500 PSI) burn rates can be quite different than the elevated pressure deflagration rate measurements (see References and HPP results discussed herein), hence elevated pressure measurements are necessary in order understand the deflagration behavior under relevant conditions. Previous work on explosives have shown that at 100's of MPa some explosives will transition from a laminar burn mechanism to a convective burn mechanism in a process termed deconsolidative burning. The resulting burn rates that are orders-of-magnitude faster than the laminar burn rates. Materials that transition to the deconsolidative-convective burn mechanism at elevated pressures have been shown to be considerably more violent in confined heating experiments (i.e. cook-off scenarios). The mechanisms of propellant and explosive deflagration are extremely complex and include both chemical, and mechanical processes, hence predicting the behavior and rate of a novel material or formulation is difficult if not impossible. In this work, the AP/HTPB based material, TAL-1503 (B-2049), was burned in a constant volume apparatus in argon up to 300 MPa (ca. 44 kPSI). The burn rate and pressure were measured in-situ and used to calculate a pressure dependent burn rate. In general, the material appears to burn in a laminar fashion at these elevated pressures. The experiment was reproduced multiple times and the burn rate law using the best data is B = (0.6 {+-} 0.1) x P{sup (1.05{+-}0.02)} where B is the burn rate in mm/s and P is the pressure in units of MPa. Details of the experimental method, results and data analysis are discussed herein and briefly compared to other AP based materials that have been measured in this apparatus.

Method and apparatus to measure the depth of skin burns  

DOE Patents [OSTI]

A new device for measuring the depth of surface tissue burns based on the rate at which the skin temperature responds to a sudden differential temperature stimulus. This technique can be performed without physical contact with the burned tissue. In one implementation, time-dependent surface temperature data is taken from subsequent frames of a video signal from an infrared-sensitive video camera. When a thermal transient is created, e.g., by turning off a heat lamp directed at the skin surface, the following time-dependent surface temperature data can be used to determine the skin burn depth. Imaging and non-imaging versions of this device can be implemented, thereby enabling laboratory-quality skin burn depth imagers for hospitals as well as hand-held skin burn depth sensors the size of a small pocket flashlight for field use and triage.

The gas from the well is burned off at the site, and the oil is immediately pumped into Kuwait's oil gathering system. Diverters inside the separator prevent the oil jet coming out of the well from reaching the top vents where the gas is burned. The oil falls back down, and is pumped from an annular oil catcher at the bottom of the separator, or from the concrete cellar surrounding the well.

Burning hazardous waste in cement kilns  

SciTech Connect (OSTI)

The cement manufacturing process is one of the oldest in the world, having been in practice for over 2000 years. It is also one of the most energy intensive, with up to 65 percent of the cost of the product attributable to energy consumption. In addition to high energy demand, the process conditions include extremely high temperatures. Cement clinker forms when the correct mixture of raw materials is heated to 2650/sup 0/ F. This requires combustion temperatures exceeding 3000/sup 0/ F. under oxidizing conditions. To accomplish this, gas temperatures above 2000/sup 0/ F. occur for several seconds (typically five seconds), which is much longer than residence times in permitted hazardous waste incinerators. These conditions are extremely favorable to the destruction of organic compounds and have led to extensive investigation into the potential for burning hazardous waste in cement kilns. Cement kilns consuming hazardous wastes have been tested for air emissions under various operating conditions. The substantial body of information on the emissions and handling of hazardous wastes from these studies has demonstrated that effective destruction of wastes can be accomplished with the added benefits of energy conservation and no significant change in air emissions.

Spectral hole burning for stopping light  

SciTech Connect (OSTI)

We propose a protocol for storage and retrieval of photon wave packets in a {lambda}-type atomic medium. This protocol derives from spectral hole burning and takes advantages of the specific properties of solid-state systems at low temperature, such as rare-earth ion-doped crystals. The signal pulse is tuned to the center of the hole that has been burnt previously within the inhomogeneously broadened absorption band. The group velocity is strongly reduced, being proportional to the hole width. This way the optically carried information and energy are carried over to the off-resonance optical dipoles. Storage and retrieval are performed by conversion to and from ground-state Raman coherence by using brief {pi} pulses. The protocol exhibits some resemblance with the well-known electromagnetically induced transparency process. It also presents distinctive features such as the absence of coupling beam. In this paper we detail the various steps of the protocol, summarize the critical parameters, and theoretically examine the recovery efficiency.

Patients with severe burns have catecholamine-mediated hypermetabolism, including pronounced muscle-protein catabolism, that adversely affects recovery. In a prospective, randomized study, 13 children with severe burns were given oral propranolol for up to four weeks in an attempt to interrupt this process, and 12 served as controls. Beta-blockade decreased resting energy expenditure and increased net muscle-protein balance by 82 percent, as compared with a 27 percent decrease in net muscle-protein balance in the control group.

Actinide burning in the integral fast reactor  

SciTech Connect (OSTI)

During the past few years, Argonne National Laboratory has been developing the integral fast reactor (IFR), an advanced liquid-metal reactor concept. In the IFR, the inherent properties of liquid-metal cooling are combined with a new metallic fuel and a radically different refining process to allow breakthroughs in passive safety, fuel cycle economics, and waste management. A key feature of the IFR concept is its unique pyroprocessing. Pyroprocessing has the potential to radically improve long-term waste management strategies by exploiting the following attributes: 1. Minor actinides accompany plutonium product stream; therefore, actinide recycling occurs naturally. Actinides, the primary source of long-term radiological toxicity, are removed from the waste stream and returned to the reactor for in situ burning, generating useful energy. 2. High-level waste volume from pyroprocessing call be reduced substantially as compared with direct disposal of spent fuel. 3. Decay heat loading in the repository can be reduced by a large factor, especially for the long-term burden. 4. Low-level waste generation is minimal. 5. Troublesome fission products, such as [sup 99]Tc, [sup 129]I, and [sup 14]C, are contained and immobilized. Singly or in combination, the foregoing attributes provide important improvements in long-term waste management in terms of the ease in meeting technical performance requirements (perhaps even the feasibility of demonstrating that technical performance requirements can be met) and perhaps also in ultimate public acceptance. Actinide recycling, if successfully developed, could well help the current repository program by providing an opportunity to enhance capacity utilization and by deferring the need for future repositories. It also represents a viable technical backup option in the event unforeseen difficulties arise in the repository licensing process.

Potential health impacts of burning coal beds and waste banks  

Science Journals Connector (OSTI)

Uncontrolled release of pollutants from burning coal beds and waste banks presents potential environmental and human health hazards. On a global scale, the emissions of large volumes of greenhouse gases from burning coal beds may contribute to climate change that alters ecosystems and patterns of disease occurrence. On regional and local scales, the emissions from burning coal beds and waste banks of acidic gases, particulates, organic compounds, and trace elements can contribute to a range of respiratory and other human health problems. Although there are few published reports of health problems caused by these emissions, the potential for problems can be significant. In India, large numbers of people have been displaced from their homes because of health problems caused by emissions from burning coal beds. Volatile elements such as arsenic, fluorine, mercury, and selenium are commonly enriched in coal deposits. Burning coal beds can volatilize these elements, which then can be inhaled, or adsorbed on crops and foods, taken up by livestock or bioaccumulated in birds and fish. Some of these elements can condense on dust particles that can be inhaled or ingested. In addition, selenium, arsenic, lead, tin, bismuth, fluorine, and other elements condense where the hot gaseous emissions come in contact with ambient air, forming mats of concentrated efflorescent minerals on the surface of the ground. These mats can be leached by rainwater and washed into local water bodies providing other potential routes of exposure. Although there are little data linking burning coal beds and waste banks to known health problems, a possibly analogous situation exists in rural China where mineralized coal burned in a residential environment has caused widespread and severe health problems such as fluorosis and arseniasis.

Nonphotochemical hole burning and dispersive kinetics in amorphous solids  

SciTech Connect (OSTI)

Results covering burn intensities in the nW to {mu}W/cm{sup 2} range, of dispersive hole growth kinetics are reported for Oxazine 720 in glycerol glasses and polyvinyl alcohol polymer films and their deuterated analogues. A theoretical model which employs a distribution function for the hole burning rate constant based upon a Gaussian distribution for the tunnel parameter is shown to accurately describe the kinetic data. This model incorporates the linear electron-phonon coupling. A method for calculating the nonphotochemical quantum yield is presented which utilizes the Gaussian distribution of tunnel parameters. The quantum yield calculation can be extended to determine a quantum yield as a function of hole depth. The effect of spontaneous hole filling is shown to be insignificant over the burn intensity range studied. Average relaxation rates for hole burning are {approximately}8 orders of magnitude greater than for hole filling. The dispersive kinetics of hole burning are observed to be independent over the temperature range of these experiments, 1.6 to 7.0 K. 6 refs., 20 figs., 1 tab.

Experiments related to the resuspension of aerosols during hydrogen burns  

SciTech Connect (OSTI)

We have performed seven ''add-on'' experiments in two large combustion facilities to investigate the capability of hydrogen burns to remove simulated structural and fission product aerosols previously deposited on small metal discs that have surfaces prototypical of those found in nuclear reactor containments. Our results suggest that hydrogen combustion provides an especially effective mechanism for removal (and, presumably, resuspension) of sedimented aerosols produced in a hypothetical nuclear reactor core-degradation or core-melting accident. The presence of condensing steam does not seem to assure adhesion of sedimented aerosols during hydrogen burns. Differences are exhibited between different surfaces as well as between types of aerosol. In-depth studies will be required to assess the impact exposure of sedimented aerosols to hydrogen burns might have on the radiological source term.

Theory of Antineutrino Monitoring of Burning MOX Plutonium Fuels

This letter presents the physics and feasibility of reactor antineutrino monitoring to verify the burnup of plutonium loaded in the reactor as a Mixed Oxide (MOX) fuel. It examines the magnitude and temporal variation in the antineutrino signals expected for different MOX fuels, for the purposes of nuclear accountability and safeguards. The antineutrino signals from reactor-grade and weapons-grade MOX are shown to be distinct from those from burning low enriched uranium. Thus, antineutrino monitoring could be used to verify the destruction of plutonium in reactors, though verifying the grade of the plutonium being burned is found to be more challenging.

False color viewing device  

DOE Patents [OSTI]

This invention consists of a viewing device for observing objects in near-infrared false-color comprising a pair of goggles with one or more filters in the apertures, and pads that engage the face for blocking stray light from the sides so that all light reaching, the user`s eyes come through the filters. The filters attenuate most visible light and pass near-infrared (having wavelengths longer than approximately 700 nm) and a small amount of blue-green and blue-violet (having wavelengths in the 500 to 520 nm and shorter than 435 nm, respectively). The goggles are useful for looking at vegetation to identify different species and for determining the health of the vegetation, and to detect some forms of camouflage.

Paediatric medical trauma: The impact on parents of burn survivors  

Science Journals Connector (OSTI)

In order to identify parents at risk of developing ongoing psychological distress after their child has sustained a burn a greater understanding of paediatric medical trauma is required. Aim To investigate the impact of exposure to paediatric trauma on parents of children with a burn and to identify risk factors and relationships between psychological distress and resilience. Methods Sixty-three parents were recruited. Parents completed standardised assessments measuring symptoms of posttraumatic stress disorder (PTSD), depression, anxiety, stress, and resilience within one week of the burn occurring. Statistical analysis included t-tests, KruskalWallis one way ANOVA and Spearman's Roe. Results Parents experienced significantly more symptoms of PTSD (p=0.001) than a comparative community population. Factors including having a daughter, witnessing the event, feeling helpless or having past traumatic experiences significantly influenced symptoms of psychological distress and resilience (p=0.05). Conclusion Parents of burn survivors experience significant psychological distress with low levels of resilience. As part of standard routine care health professionals should screen parents to identify those at greatest risk and provide effective evidence based interventions aimed at improving resilience and reducing stress.

E-Print Network [OSTI]

Since the advent of powerful new X-ray observatories, NASA's Rossi X-ray Timing Explorer (RXTE), the Italian - Dutch BeppoSAX mission, XMM-Newton and Chandra, a number of entirely new phenomena associated with thermonuclear burning on neutron stars have been discovered. These include: (i) the discovery of millisecond (300 - 600 Hz) oscillations during bursts, so called ``burst oscillations'', (ii) a new regime of nuclear burning on neutron stars which manifests itself through the generation of hours long flares about once a decade, now referred to as ``superbursts'',(iii) discoveries of bursts from low accretion rate neutron stars, and (iv) new evidence for discrete spectral features from bursting neutron stars. In this article we review our current understanding of thermonuclear bursts on neutron stars, with a focus on these new phenomena.

Type Ia Supernova: Burning and Detonation in the Distributed Regime  

E-Print Network [OSTI]

A simple, semi-analytic representation is developed for nuclear burning in Type Ia supernovae in the special case where turbulent eddies completely disrupt the flame. The speed and width of the ``distributed'' flame front are derived. For the conditions considered, the burning front can be considered as a turbulent flame brush composed of corrugated sheets of well-mixed flames. These flames are assumed to have a quasi-steady-state structure similar to the laminar flame structure, but controlled by turbulent diffusion. Detonations cannot appear in the system as long as distributed flames are still quasi-steady-state, but this condition is violated when the distributed flame width becomes comparable to the size of largest turbulent eddies. When this happens, a transition to detonation may occur. For current best estimates of the turbulent energy, the most likely density for the transition to detonation is in the range 0.5 - 1.5 x 10^7 g cm^{-3}.

Delineation of a coal burn edge with seismic refraction  

SciTech Connect (OSTI)

Coal seams in many areas of western United States have ignited and burned for considerable distances underground. The boundary between the coal and clinker needs to be defined for determination of reserves. Field tests of a seismic refraction method were conducted at Kerr-McGee Coal Corp's open pit Clovis Point mine near Gillette, Wyoming. Explosive sources were detonated in shot holes in the pit floor. Geophone lines, laid on the surface beyond the edge of the pit, crossed from an area of known coal to an area of clinker. Delays in arrival times correlated with the expected beginning of the clinker zone. Waves passing through the clinker also exhibit a significant attenuation. A magnetic survey concluded along the seismic lines showed anomalies in the regions where seismic data indicated the burn edge.

Emission factor estimates of cereal waste burning in Spain  

Science Journals Connector (OSTI)

Every year more than 5 million ha of cereal fields are affected by fires in order to eliminate cereal waste in Spain. The characteristics of this type of fire with intense flames are similar to those of the African dry savanna heading fires. This paper surveys the atmospheric emission caused by this process by combining results of field and combustion chamber experiments. Combustion chamber experiments show that during the flaming phase 88% of the fire exposed carbon is converted into CO2 and during the smoldering phase this percentage changes to 74%. These combustion chamber experiments also show that the soluble part of the aerosols emitted during the course of fires only represent 3% of the total particulate matter (TPM) produced, being the ions K+ and CI? the predominant ones. The cereal waste fire process can be represented by an arithmetic combination that takes into account the amounts of mass burned during the two phases of the fire: 0.90 flaming +0.10 smoldering. Emission factor estimates from field burning experiment are 137g TPMkg?1(dm) and 2.80.2g NOxkg?1 (dm). Finally, we obtain average emissions of 80130Gg TPM, 1728Gg NOx, 210350Gg CO and 814Tg CO2 in Spain. These emissions represent nearly 25% of the total \\{NOx\\} and 50% of the total CO2 emissions by other pollution sources during the burning period in Spain.

Particulate matter characteristics during agricultural waste burning in Taichung City, Taiwan  

Science Journals Connector (OSTI)

Agricultural waste burning is performed after harvest periods in June and November in Taiwan. Typically, farmers use open burning to dispose of excess rice straw. PM2.5 and PM2.510 measurements were conducted at National Chung Hsing University in Taichung City using a dichotomous sampler. The sampling times were during straw burning periods after rice harvest during 20022005. Ionic species including SO42?, NO3?, NH4+, K+, Ca2+, Cl? and Na+ and carbonaceous species (EC and OC) in PM2.5 and PM2.510 were analyzed. The results showed that the average PM2.5 and PM2.510 concentrations were 123.6 and 31.5?gm?3 during agricultural waste burning periods and 32.6 and 21.4?gm?3 during non-waste burning periods, respectively. The fine aerosol ionic species including Cl?, K+ and NO3? increased 11.0, 6.7 and 5.5 times during agricultural burning periods compared with periods when agricultural waste burning is not performed. K+ was found mainly in the fine mode during agricultural burning. High nitrogen oxidation ratio was found during agricultural waste burning periods which might be caused by the conversion of Nitrogen dioxide (NO2) to NO3?. It is concluded that agricultural waste burning with low dispersion often causes high PM2.5 and gases pollutant events.

Research on methanol-burning, two-stroke engines  

SciTech Connect (OSTI)

In looking for the possibility of burning methanol in the two-stroke marine diesel engine, Mitsubishi decided that its investigations would be for a pure methanol-burning engine. Since ignition of methanol by the straight forward diesel cycle is not attainable, Mitsubishi decided to use glow plugs for ignition. The result has been the adaptation of the 450 mm bore test engine, at Nagasaki, with a special cylinder head carrying two methanol precombustion chambers and two main methanol injectors. Results from the tests at Nagasaki showed that NO[sub x] formation was no more than 500 ppm at full load, while thermal efficiency was at least equal to that of a straight diesel engine. A base model ship for Japanese coastal waters operation is being studied. Plans of the ship have been sent to the Japanese classification society, NK, and they include a separate methanol treatment room and storage tanks. The committee concluded that a methanol-engined ship of about 1000 dwt can be operated economically with a relatively small increase in freight rate. Lower crew costs are part of that equation, because of an expected decrease in machinery maintenance. Conceptual approval for the project is now being sought with NK. 2 figs.

Census and viewing of organisms Census and viewing of organisms Name: m hariaczyi Status: N/A Age: N/A Location: N/A Country: N/A Date: Around 1993 Question: How many organisms exist in the world today? What is the most powerful microscope that could be used for viewing organism? Replies: The most powerful microscope is called an electron microscope, which can be used for viewing entire organisms, although few organisms are small enough to see all of them at high magnifications allowed by this microscope. So most often its used to look at fixed sections of organisms. Since the electron microscope only works in a vacuum, with no air, you cannot look at live organisms. To do that, probably the most powerful microscope is called a Nomarski, or in technical terms, a "differential interference contrast" microscope. This is a modification of a normal light microscope that allows better contrast in living tissue. It is not any more powerful than a light microscope, and is much less powerful than an electron microscope, but it allows you to see living things much better.

Assessment of Rich-Burn, Quick-Mix, Lean-Burn Trapped Vortex Combustor for Stationary Gas Turbines  

SciTech Connect (OSTI)

This paper describes the evaluation of an alternative combustion approach to achieve low emissions for a wide range of fuel types. This approach combines the potential advantages of a staged rich-burn, quick-mix, lean-burn (RQL) combustor with the revolutionary trapped vortex combustor (TVC) concept. Although RQL combustors have been proposed for low-Btu fuels, this paper considers the application of an RQL combustor for high-Btu natural gas applications. This paper will describe the RQL/TVC concept and experimental results conducted at 10 atm (1013 kPa or 147 psia) and an inlet-air temperature of 644 K (700F). The results from a simple network reactor model using detailed kinetics are compared to the experimental observations. Neglecting mixing limitations, the simplified model suggests that NOx and CO performance below 10 parts per million could be achieved in an RQL approach. The CO levels predicted by the model are reasonably close to the experimental results over a wide range of operating conditions. The predicted NOx levels are reasonably close for some operating conditions; however, as the rich-stage equivalence ratio increases, the discrepancy between the experiment and the model increases. Mixing limitations are critical in any RQL combustor, and the mixing limitations for this RQL/TVC design are discussed.

The evolution of solid density within a thermal explosion II. Dynamic proton radiography of cracking and solid consumption by burning  

SciTech Connect (OSTI)

We report proton transmission images obtained subsequent to the laser assisted thermal ignition of a sample of PBX 9501 (a plastic bonded formulation of the explosive nitramine octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine (HMX)). We describe the laser assisted thermal ignition technique as a means to synchronize a non-linear thermal ignition event while preserving the subsequent post-ignition behavior. We have obtained dynamic proton transmission images at two spatial magnifications and viewed both the radial and transverse axis of a solid cylindrical sample encased in aluminum. Images have been obtained with 3 to 15 {mu}s temporal resolution and approximately 100 {mu}m spatial resolution at the higher magnification. We observe case expansion from very early in the experiment, until case fragmentation. We observe spatially anisotropic features in the transmission which we attribute to cracking in the solid explosive, in agreement with previous measurements conducted on two dimensional samples with optical viewing. Digital analysis of the images also reveals spatially isotropic features which we attribute to the evolution of the loss of density by burning subsequent to thermal ignition.

Mercury control technologies for Mercury control technologies for electric utilities Burning lignite coal Background In partnership with a number of key stakeholders, the U.S. Department of Energy's Office of Fossil Energy (DOE/FE), through its National Energy Technology Laboratory (NETL), has been carrying out a comprehensive research program since the mid-1990s focused on the development of advanced, cost-effective mercury (Hg) control technologies for coal-fired power plants. Mercury is a poisonous metal found in coal, which can be harmful and even toxic when absorbed from the environment and concentrated in animal tissues. Mercury is present as an unwanted by-product of combustion in power plant flue gases, and is found in varying percentages in three basic chemical forms(known as speciation): particulate-bound mercury, oxidized

Advanced atomization concept for CWF burning in small combustors  

SciTech Connect (OSTI)

The present project involves the second phase of research on a new concept in coal-water fuel (CWF) atomization that is applicable to burning in small combustors. It is intended to address the most important problem associated with CWF combustion; i.e., production of small spray droplets in an efficient manner by an atomization device. Phase 1 of this work was successfully completed with the development of an opposed-jet atomizer that met the goals of the first contract. Performance as a function of operating conditions was measured, and the technical feasibility of the device established in the Atlantic Research Atomization Test Facility employing a Malvern Particle Size Analyzer. Testing then proceeded to a combustion stage in a test furnace at a firing rate of 0.5 to 1.5 MMBtu/H.

Explosive hydrogen burning during type I X-ray bursts  

SciTech Connect (OSTI)

Explosive hydrogen burning in type I X-ray bursts (XRBs) is driven by charged particle reactions creating isotopes with masses up to A {approx} 100. Since charged particle reactions in a stellar environment are very temperature sensitive, we use a realistic time-dependent general relativistic and self-consistent model of type I X-ray bursts to provide accurate values of the burst temperatures and densities. This allows a detailed and accurate time-dependent identification of the reaction flow from the surface layers through the convective region and the ignition region to the neutron star ocean. Using this, we determine the relative importance of specific nuclear reactions in the X-ray burst.

Pellet fuelling requirements to allow self-burning on a helical-type fusion reactor  

Science Journals Connector (OSTI)

Pellet refuelling conditions to sustain a self-burning plasma have been investigated by extrapolating the confinement property of the LHD plasma, which appears to be governed by a gyro-Bohm-type confinement property. The power balance of the burning plasma is calculated taking into account the profile change with pellet deposition and subsequent density relaxation. A self-burning plasma is achieved within the scope of conventional pellet injection technology. However, a very small burn-up rate of 0.18% is predicted. Higher velocity pellet injection is effective in improving the burn-up rate by deepening particle deposition, whereas deep fuelling leads to undesirable fluctuation of the fusion output.

Influence of local waste burning on atmospheric aerosol properties in urban environment  

Science Journals Connector (OSTI)

Aerosols affect the radiative energy budget on both the regional and global scales. The wavelength-dependent aerosol optical depth (AOD) is a fundamental determinant of the amount by which extra-terrestrial incoming sunlight and outgoing terrestrial radiation are being attenuated in the atmosphere. The present study addresses the influence of local waste burning on aerosol characteristics, black carbon (BC) aerosol mass concentration and spectral solar irradiance using ground-based measurements over the tropical urban environment of Hyderabad, India. AOD has been observed to be maximum during burning days compared to normal days. Aerosol size spectra suggest bimodal distributions during pre-and post-burning periods and trimodal distributions during burning periods. Angstrom wavelength exponent estimated from spectral variation of AOD suggested dominance of accumulation mode particle loading during burning days compared to normal days. Diurnal variation of BC on normal days showed a broad nocturnal peak during ?20:00 to ?24:00h with a maximum value of BC aerosol concentration of ?14,000ngm?3 whereas on local waste burning days enormous increases in BC concentrations have been observed with a peak at ?60,000ngm?3. Relative attenuation of global solar irradiance during burning days has been found to be of the order of 30% in the visible and 28% in the near-infrared regions. The results are discussed in detail in this paper.

Cereal waste burning pollution observed in the town of Vitoria (northern Spain)  

Science Journals Connector (OSTI)

Agricultural waste burning is a widespread practice throughout the world but there is little information about its pollutant impact. This paper deals with a preliminary study of the pollution observed in Vitoria (Northern Spain) caused by cereal waste burning. The mean hourly flux of pollutants produced by cereal waste burning fires can reach values of 1.4kt of CO2, 13t of TPM and 3t of \\{NOx\\} in the area around Vitoria. Measurements obtained in the area of emission and inside fire plumes show high ratios (NO2/NOx) indicating that nitrogen oxides emitted by the source undergo a rapid transformation in the same area of emission. Results relating to aerosol composition collected in Vitoria during burning periods show an increase in the concentration of K+, NO3? and Cl? ions, that are inter-correlated. The modification of the ionic composition of aerosols also affects the chemistry of the rain collected in Vitoria. During the burning period, it is particularly noticeable that anthropogenic pollution (usually identifiable by the correlation between SO42? and NO3? concentrations) disappears, indicating the existence of an independent source of NO3? not linked to the SO42? source. Similar results were deduced studying BAPMON data collected in Spain during cereal waste burning. Finally, we note that ozone concentration measured at Vitoria is not affected by the pollution generated by the burning fires.

Emission and transport of cesium-137 from boreal biomass burning in the summer of 2010  

SciTech Connect (OSTI)

While atmospheric concentrations of cesium-137 have decreased since the nuclear testing era, resuspension of Cs-137 during biomass burning provides an ongoing emission source. The summer of 2010 was an intense biomass burning season in western Russia, with high levels of particulate matter impacting air quality and visibility. A radionuclide monitoring station in western Russia shows enhanced airborne Cs-137 concentrations during the wildfire period. Since Cs-137 binds to aerosols, satellite observations of aerosols and fire occurrences can provide a global-scale context for Cs-137 emissions and transport during biomass burning events.

Transverse liquid fuel jet breakup, burning, and ignition  

SciTech Connect (OSTI)

An analytical/numerical study of the breakup, burning, and ignition of liquid fuels injected transversely into a hot air stream is conducted. The non-reacting liquid jet breakup location is determined by the local sonic point criterion first proposed by Schetz, et al. (1980). Two models, one employing analysis of an elliptical jet cross-section and the other employing a two-dimensional blunt body to represent the transverse jet, have been used for sonic point calculations. An auxiliary criterion based on surface tension stability is used as a separate means of determining the breakup location. For the reacting liquid jet problem, a diffusion flame supported by a one-step chemical reaction within the gaseous boundary layer is solved along the ellipse surface in subsonic crossflow. Typical flame structures and concentration profiles have been calculated for various locations along the jet cross-section as a function of upstream Mach numbers. The integrated reaction rate along the jet cross-section is used to predict ignition position, which is found to be situated near the stagnation point. While a multi-step reaction is needed to represent the ignition process more accurately, the present calculation does yield reasonable predictions concerning ignition along a curved surface.

Dispersion model development for open burn/open detonation sources  

SciTech Connect (OSTI)

The disposal of obsolete munitions, propellants, and manufacturing wastes is conducted at Department of Defense (DOD) and Department of Energy (DOE) facilities. The most common disposal method is open burning (OB) and open detonation (OD) of the material, which occurs in an earthen pit or bermed area. OB/OD operations generate air pollutants and require predictions of pollutant concentrations. The pollutants include SO{sub 2}, NO{sub x}, particulates, volatile organic compounds and toxic materials such as metals, semivolatile organics, etc. Dispersion models are used to estimate pollutant concentrations given the source and meteorological conditions. However, there is currently no recommended EPA dispersion model to address OB/OD sources. Due to the constraints of existing models, a model development program was initiated under the DOD/DOE Strategic Environmental Research and Development Program. In Section 2, the authors give an overview of the model design which is divided into simple and research components. Sections 3 and 4 describe the simple component which includes Gaussian puff and analytic plume models.

Interaction of fast particles and Alfven modes in burning plasmas  

SciTech Connect (OSTI)

In this paper we study the interaction of fast particles with Alfvenic instabilities in Tokamak plasmas, with reference to present-day experiments that exploit strong energetic particle heating (namely, JT-60U) and the consistency of proposed ITER burning plasma scenarios. Concerning JT-60U, two different types of bursting modes have been observed by MHD spectrography in auxiliary heated (NNB) discharges. One of these modes has been dubbed fast frequency sweeping (fast FS) mode. It is characterized by a timescale of the order of few milliseconds and frequencies branching upwards and downwards. The other mode, called the abrupt large-amplitude event (ALE), has shorter timescale (order of hundred microseconds) and larger amplitude. On the occurrence of ALEs, a significant reduction of the neutron emission rate in the central plasma region is observed. Such a change has been attributed to a redistribution of the energetic ions, with a marked reduction of their on-axis density. We present an interpretation of these experimental observations, based on the results of nonlinear particle simulations performed by the Hybrid MHD-Gyrokinetic Code HMGC.Concerning ITER, monotonic-q (scenario 2) and reversed-shear (scenario 4) equilibria are considered. Also an ITER hybrid scenario is examined and quantitatively compared with the previous ones. The transition from the low-amplitude Alfvenic instability saturation to the secondary excitation of a stronger mode is addressed, and its effect on the energetic particle transport analyzed.

The EBR-II X501 Minor Actinide Burning Experiment  

SciTech Connect (OSTI)

The X501 experiment was conducted in EBR-II as part of the IFR (Integral Fast Reactor) program to demonstrate minor actinide burning through the use of a homogeneous recycle scheme. The X501 subassembly contained two metallic fuel elements loaded with relatively small quantities of americium and neptunium. Interest in the behavior of minor actinides (MA) during fuel irradiation has prompted further examination of existing X501 data, and generation of new data where needed in support of the U.S. waste transmutation effort. The X501 experiment is one of the few minor actinide-bearing fuel irradiation tests conducted worldwide and knowledge can be gained by understanding the changes in fuel behavior due to addition of MAs. Of primary interest are the affect of the MAs on fuel-cladding-chemical-interaction, and the redistribution behavior of americium. The quantity of helium gas release from the fuel and any effects of helium on fuel performance are also of interest. It must be stressed that information presented at this time is based on the limited PIE conducted in 1995-1996, and currently represents a set of observations rather than a complete understanding of fuel behavior. This paper provides a summary of the X501 fabrication, characterization, irradiation, and post irradiation examination.

Vertical feed stick wood fuel burning furnace system  

DOE Patents [OSTI]

A new and improved stove or furnace for efficient combustion of wood fuel including a vertical feed combustion chamber for receiving and supporting wood fuel in a vertical attitude or stack, a major upper portion of the combustion chamber column comprising a water jacket for coupling to a source of water or heat transfer fluid and for convection circulation of the fluid for confining the locus of wood fuel combustion to the bottom of the vertical gravity feed combustion chamber. A flue gas propagation delay channel extending from the laterally directed draft outlet affords delayed travel time in a high temperature environment to assure substantially complete combustion of the gaseous products of wood burning with forced air as an actively induced draft draws the fuel gas and air mixture laterally through the combustion and high temperature zone. Active sources of forced air and induced draft are included, multiple use and circuit couplings for the recovered heat, and construction features in the refractory material substructure and metal component superstructure.

A major upper portion of the combustion chamber column comprises a water jacket (14) for coupling to a source of water or heat transfer fluid for convection circulation of the fluid. The locus (31) of wood fuel combustion is thereby confined to the refractory base of the combustion chamber. A flue gas propagation delay channel (34) extending laterally from the base of the chamber affords delayed travel time in a high temperature refractory environment sufficient to assure substantially complete combustion of the gaseous products of wood burning with forced air prior to extraction of heat in heat exchanger (16). Induced draft draws the fuel gas and air mixture laterally through the combustion chamber and refractory high temperature zone to the heat exchanger and flue. Also included are active sources of forced air and induced draft, multiple circuit couplings for the recovered heat, and construction features in the refractory material substructure and metal component superstructure.

Combustion aerosols formed during burning of radioactively contaminated materials: Experimental results  

SciTech Connect (OSTI)

Safety assessments and environmental impact statements for nuclear fuel cycle facilities require an estimate of potential airborne releases. Radioactive aerosols generated by fires were investigated in experiments in which combustible solids and liquids were contaminated with radioactive materials and burned. Uranium in powder and liquid form was used to contaminate five fuel types: polychloroprene, polystyrene, polymethylmethacrylate, cellulose, and a mixture of 30% tributylphosphate (TBP) in kerosene. Heat flux, oxygen concentration, air flow, contaminant concentration, and type of ignition were varied in the experiments. The highest release (7.1 wt %) came from burning TBP/kerosene over contaminated nitric acid. Burning cellulose contaminated with uranyl nitrate hexahydrate liquid gave the lowest release (0.01 wt %). Rate of release and particle size distribution of airborne radioactive particles were highly dependent on the type of fuel burned.

A PHILOSOPHICAL VIEW OF CIVILIZATION  

Science Journals Connector (OSTI)

Publisher Summary Civilization comprises the dynamic interchange or transaction between three open entitieshuman nature, values and environment, physical and idealand can be understood only as their emergence or transcendence. The scientific and technological age views civilization in East or West largely in the context of man's control and manipulation of nature. The furniture and appurtenances of civilized living, the scaffolding and the frame-work rather than the mansion itself loom larger in the picture. However, the mansion of civilization is represented by the insights, appreciations, values and aspirations of mankind. It is these enduring experiences of the race which embody the essence of civilization and should obtain primary consideration in any adequate treatment. As the philosophy of science and technology makes a tour round the globe, the meanings, appreciations, and values that civilization actually experiences in its orientation to cosmos and to existence as a whole are discounted as metaphysical and religiousirrelevant for modern secular culture.

Ultraslow Wave Nuclear Burning of Uranium-Plutonium Fissile Medium on Epithermal Neutrons  

E-Print Network [OSTI]

For a fissile medium, originally consisting of uranium-238, the investigation of fulfillment of the wave burning criterion in a wide range of neutron energies is conducted for the first time, and a possibility of wave nuclear burning not only in the region of fast neutrons, but also for cold, epithermal and resonance ones is discovered for the first time. For the first time the results of the investigation of the Feoktistov criterion fulfillment for a fissile medium, originally consisting of uranium-238 dioxide with enrichments 4.38%, 2.00%, 1.00%, 0.71% and 0.50% with respect to uranium-235, in the region of neutron energies 0.015-10.0eV are presented. These results indicate a possibility of ultraslow wave neutron-nuclear burning mode realization in the uranium-plutonium media, originally (before the wave initiation by external neutron source) having enrichments with respect to uranium-235, corresponding to the subcritical state, in the regions of cold, thermal, epithermal and resonance neutrons. In order to validate the conclusions, based on the slow wave neutron-nuclear burning criterion fulfillment depending on the neutron energy, the numerical modeling of ultraslow wave neutron-nuclear burning of a natural uranium in the epithermal region of neutron energies (0.1-7.0eV) was conducted for the first time. The presented simulated results indicate the realization of the ultraslow wave neutron-nuclear burning of the natural uranium for the epithermal neutrons.

Carbon, water, and heat flux responses to experimental burning and drought Carbon, water, and heat flux responses to experimental burning and drought in a tallgrass prairie Title Carbon, water, and heat flux responses to experimental burning and drought in a tallgrass prairie Publication Type Journal Article Year of Publication 2012 Authors Fischer, Marc L., Margaret S. Torn, David P. Billesbach, Geoffrey Doyle, Brian Northup, and Sebastien C. Biraud Journal Agricultural and Forest Meteorology Volume 166-167 Pagination 169-174 Keywords Carbon exchange, eddy covariance, Fire, Grassland, Prairie, Water stress Abstract Drought and fire are common disturbances to grassland ecosystems. We report two years of eddy covariance ecosystem-atmosphere fluxes and biometric variables measured in nearby burned and unburned pastures in the US Southern Great Plains. Over the course of the experiment, annual precipitation (∼600 mm yr-1) was lower than the long term mean (∼860 mm yr-1). Soil moisture decreased from productive conditions in March 2005 dry, unproductive conditions during the growing season starting in March 2006. Just prior to the burn in early March 2005, burned and unburned pastures contained 520 ± 60 and 360 ± 40 g C m-2 of total above ground biomass (AGB) and litter, respectively. The fire removed approximately 200 g C m-2 of litter and biomass. In the 2005 growing season following the burn, maximum green AGB was 450 ± 60 and 270 ± 40 g C m-2, with corresponding cumulative annual net ecosystem carbon exchange (NEE) of -330 and -150 g C m-2 for the burned and unburned pastures, respectively. In contrast to NEE, cumulative mean sensible heat and water fluxes were approximately equal in both pastures during the growing season, suggesting either an increase in water use efficiency or a decrease in evaporation in the burned relative to the unburned pasture. In the 2006 growing season, dry conditions decreased carbon uptake and latent heat, and increased sensible heat fluxes. Peak AGB was reduced to 210 ± 30 g C m-2 and 140 ± 30 g C m-2 in the burned and unburned pastures, respectively, while NEE was near zero. These results suggest that the lack of precipitation was responsible for most of the interannual variation in carbon exchange for these un-irrigated prairie pastures.

Method and apparatus for controlling fuel/air mixture in a lean burn engine  

DOE Patents [OSTI]

The system for controlling the fuel/air mixture supplied to a lean burn engine when operating on natural gas, gasoline, hydrogen, alcohol, propane, butane, diesel or any other fuel as desired. As specific humidity of air supplied to the lean burn engine increases, the oxygen concentration of exhaust gas discharged by the engine for a given equivalence ratio will decrease. Closed loop fuel control systems typically attempt to maintain a constant exhaust gas oxygen concentration. Therefore, the decrease in the exhaust gas oxygen concentration resulting from increased specific humidity will often be improperly attributed to an excessive supply of fuel and the control system will incorrectly reduce the amount of fuel supplied to the engine. Also, the minimum fuel/air equivalence ratio for a lean burn engine to avoid misfiring will increase as specific humidity increases. A relative humidity sensor to allow the control system to provide a more enriched fuel/air mixture at high specific humidity levels. The level of specific humidity may be used to compensate an output signal from a universal exhaust gas oxygen sensor for changing oxygen concentrations at a desired equivalence ratio due to variation in specific humidity specific humidity. As a result, the control system will maintain the desired efficiency, low exhaust emissions and power level for the associated lean burn engine regardless of the specific humidity level of intake air supplied to the lean burn engine.

Laminar burning velocity with oxygen-enriched air of syngas produced from biomass gasification  

Science Journals Connector (OSTI)

Abstract Several studies on the laminar burning velocity of syngas mixtures have been conducted by various researchers. However, in most of these studies, dry air was used as the oxidizer, whereas very few studies have been conducted on syngas combustion in oxygen enriched air. In this work, a numerical and experimental study on the laminar burning velocity of a mixture of H2, CO and N2 (20:20:60vol%) was performed using air enriched with oxygen as the oxidizer, varying the oxygen content from 21% up to 35% for different equivalence ratios. Numerical calculations were conducted using three detailed reaction mechanisms and transport properties. Flames were generated using contoured slot-type nozzle burners, and Schlieren images were used to determine the laminar burning velocity with the angle method. The experiments were performed under the conditions of Medellin (1550m.a.s.l.), 0.838atm and 298K. The laminar burning velocity increases with the concentration of the oxygen in the mixture due to the increase of the reaction rate; for a stoichiometric mixture, the laminar burning velocity increases by almost 25% with an increment of 4% of oxygen in the oxidant. However, the flammability limits also increase, allowing stable flames to exist in a wider range of equivalence ratios.

Study of the burning capability of the los alamos ATW system  

Science Journals Connector (OSTI)

The aim of calculations is to evaluate the evolution of the infinite multiplication factor (k inf) during the irradiation of minor actinides High Level Waste (HLW) and Plutonium. The most important results are independently verified with Monte Carlo calculations. The relative importance of the main parameters affecting the k inf was investigated by performing calculations with several minor actinide and plutonium concentrations as well as different 238U decontamination factors for HLW. The merit figure value for minor actinide alone considering a constant neutron flux indicates that the best results are reached for minor actinide concentration equal to PWR spent fuel. The best plutonium burning results are obtained for a concentration (50.23 g/l) equal to the half of PWR spent fuel one. The simulations lead to two different reactor concepts: one for HLW burning and the other for plutonium burning purposes. To burn the HLW the most suitable reactor is an homogeneous one. This kind of reactor can effectively be utilised to burn minor actinide in low concentration (namely the PWR spent fuel). On the other hand an heterogeneous reactor with channels filled by all actinides present in PWR spent fuel with the exclusion of U isotopes with a concentration of 50 g/l can be studied.

Ambient measurements of light-absorption by agricultural waste burning organic aerosols  

Science Journals Connector (OSTI)

Absorption properties (absorption ngstrom exponent and mass absorption efficiency) of agricultural waste burning organic aerosols (AWB-OA) and their impact on total absorption were investigated in Cairo (Egypt) during the post-harvest rice straw burning autumn season. At 370nm, AWB-OA were found to account for more than 25% of total absorption on average for the period of study (and for ?50% during intense biomass burning events), pointing out the major role potentially played by such particles on light absorption at short wavelengths. The absorption exponent obtained for AWB-OA (?3.5) is consistent with values previously reported for biomass burning brown carbon. In addition, AWB-OA were found to exhibit high mass absorption efficiencies at the near ultraviolet/mid-visible regions (e.g. 3.21.6m2g?1 at 370nm and 0.80.4m2g?1 at 520nm). Such findings clearly illustrate the need to take light absorption by organic aerosols into account for a better estimate of the radiative impact of biomass burning aerosols.

Effects of surface voids on burning rate measurements of pulverized coal at diffusion-limited conditions  

SciTech Connect (OSTI)

This research explores the effects of voids (pores on the particle surface that are deeper than their surface radius) on burning area at diffusion-limited combustion conditions. Scanning electron microscopy and digital processing of images of quenched particles were used to quantify surface void area, perimeter, and reacting void wall area for voids with diameters larger than 1 {micro}m. After careful analysis, the most accurate determination of particle burning area at diffusion-limited conditions was achieved by measuring particle surface area using the technique of discrete revolution, subtracting surface void area, and adding reacting void wall area. In situ measurements of reacting coal particle temperatures and images were taken for three coals and spherocarb particles at conditions that limit the formation of CO{sub 2} from reacting carbon under various oxygen concentrations and heating rates. The results of these experiments indicate that correcting the measured surface area for void area and reacting void wall area produces calculated burning rates closely matching diffusion-limited burning rates for all conditions and all coals investigated. These results suggest that void area effects should be included for accurate determination of burning area at diffusion-limited conditions.

An index for estimating resistance to infection in patients with burns  

Science Journals Connector (OSTI)

The bactericidal index (BI), which measures the bactericidal capacity of polymorphs against bacteria isolated from burns, has been used to monitor susceptibility to infection in patients with burns. On admission, patients had different BI values against different bacteria but were only susceptible to infection when the \\{BIs\\} to bacteria on their burns was low. In patients where the BI was measured against the infecting strains of Staphylococcus aureus, BI values lower than those found in healthy volunteers occurred at the onset of septicaemia and abscesses. A low BI in patients infected with Pseudomonas aeruginosa coincided with high levels of endotoxin in their peripheral blood. Patients inoculated with a new polyvalent pseudomonas vaccine had a raised BI against all strains of P. aeruginosa tested.

Fabrication of contacts for silicon solar cells including printing burn through layers  

DOE Patents [OSTI]

A method for fabricating a contact (240) for a solar cell (200). The method includes providing a solar cell substrate (210) with a surface that is covered or includes an antireflective coating (220). For example, the substrate (210) may be positioned adjacent or proximate to an outlet of an inkjet printer (712) or other deposition device. The method continues with forming a burn through layer (230) on the coating (220) by depositing a metal oxide precursor (e.g., using an inkjet or other non-contact printing method to print or apply a volume of liquid or solution containing the precursor). The method includes forming a contact layer (240) comprising silver over or on the burn through layer (230), and then annealing is performed to electrically connect the contact layer (240) to the surface of the solar cell substrate (210) through a portion of the burn through layer (230) and the coating (220).

Effective Helium Burning Rates and the Production of the Neutrino Nuclei  

E-Print Network [OSTI]

Effective values for the key helium burning reaction rates, triple-alpha and 12C(alpha,gamma)16O, are obtained by adjusting their strengths so as to obtain the best match with the solar abundance pattern of isotopes uniquely or predominately made in core collapse supernovae. These effective rates are then used to determine the production of the neutrino isotopes. The use of effective rates considerably reduces the uncertainties in the production factors arising from uncertainties in the helium burning rates, and improves our ability to use the production of 11B to constrain the neutrino emission from supernovae.

Hydrodynamic Stability Analysis of Burning Bubbles in Electroweak Theory and in QCD  

E-Print Network [OSTI]

Assuming that the electroweak and QCD phase transitions are first order, upon supercooling, bubbles of the new phase appear. These bubbles grow to macroscopic sizes compared to the natural scales associated with the Compton wavelengths of particle excitations. They propagate by burning the old phase into the new phase at the surface of the bubble. We study the hydrodynamic stability of the burning and find that for the velocities of interest for cosmology in the electroweak phase transition, the shape of the bubble wall is stable under hydrodynamic perturbations. Bubbles formed in the cosmological QCD phase transition are found to be a borderline case between stability and instability.

Open burning of household waste: Effect of experimental condition on combustion quality and emission of PCDD, PCDF and PCB  

Science Journals Connector (OSTI)

Open burning for waste disposal is, in many countries, the dominant source of polychlorinated dibenzodioxins, dibenzofurans and biphenyls (PCDD/PCDF/PCB) release to the environment. To generate emission factors for open burning, experimental pile burns of about 100kg of household waste were conducted with emissions sampling. From these experiments and others conducted by the same authors it is found that less compaction of waste or active mixing during the fire stirring promotes better combustion (as evidenced by lower CO/CO2 ratio) and reduces emissions of PCDD/PCDF/PCB; an intuitive but previously undemonstrated result. These experiments also support previous results suggesting PCDD/PCDF/PCB generation in open burning while still highly variable tends to be greater in the later (smoldering) phases of burning when the CO/CO2 ratio increases.

Production of potentially hazardous respirable silica airborne particulate from the burning of sugarcane  

Science Journals Connector (OSTI)

In some areas of the world where agricultural burning is practised, the airborne particles produced have been linked to respiratory disease in humans. Here, we investigate the abundance and form of silica (SiO2) minerals found within ash and aerosol produced by the experimental burning of sugarcane. Samples of sugarcane leaf were incinerated over a range of temperatures, time scales and airflow conditions, the latter to investigate the effects of wind and updrafts during natural fires. The silica content of the residual ash (from still air simulations) was measured using an improved wet chemical methodology, described here. This indicated that the release of silica from the plant material into the atmosphere increases with increasing temperature of combustion. Airborne particulate, sampled using air-pump-filter apparatus, was characterised using scanning electron microscopy (SEM) with automated image and elemental analysis. For airborne particulate formed at 1100C (with airflow), 17% of the particles are in the respirable size fraction (release of cristobalite to the atmosphere (as sampled on filters). This pilot study shows that potentially toxic particles could be released during sugarcane burning and reinforces the need for further study into the emissions and re-suspension of ash from the burning of biomass.

Lean burn limit and time to light characteristics of laser ignition in gas turbines  

Science Journals Connector (OSTI)

Abstract This work details a study of laser ignition in a low pressure combustion test rig, representative of an industrial gas turbine (SGT-400, Siemens Industrial Turbomachinery Ltd.) and for the first time investigates the effect of air mass flow rate on combustion characteristics at air/fuel ratios at the lean burn limit. Both the lean burn limit and time taken to light are essential in determining the suitability of a specified air/fuel ratio, especially in multi-chamber ignition applications. Through extension of the lean burn limit and reduction of the time taken to light, the operating window for ignition with regards to the air/fuel ratio can be increased, leading to greater reliability and repeatability of ignition. Ignition of a natural gas and air mixture at atmospheric pressure was conducted using both a standard high energy igniter and a laser ignition system utilizing a Q-switched Nd:YAG laser source operating at 1064nm wavelength. A detailed comparison of the lean burn limit and time taken to light for standard ignition and laser ignition is presented.

Reaction Rate and Composition Dependence of the Stability of Thermonuclear Burning on Accreting Neutron Stars  

E-Print Network [OSTI]

The stability of thermonuclear burning of hydrogen and helium accreted onto neutron stars is strongly dependent on the mass accretion rate. The burning behavior is observed to change from Type I X-ray bursts to stable burning, with oscillatory burning occurring at the transition. Simulations predict the transition at a ten times higher mass accretion rate than observed. Using numerical models we investigate how the transition depends on the hydrogen, helium, and CNO mass fractions of the accreted material, as well as on the nuclear reaction rates of triple alpha and the hot-CNO breakout reactions 15O(a,g)19Ne and 18Ne(a,p)21Na. For a lower hydrogen content the transition is at higher accretion rates. Furthermore, most experimentally allowed reaction rate variations change the transition accretion rate by at most 10%. A factor ten decrease of the 15O(a,g)19Ne rate, however, produces an increase of the transition accretion rate of 35%. None of our models reproduce the transition at the observed rate, and depend...

Persistent spectral-hole-burning spectroscopy of CuCl quantum cubes  

Science Journals Connector (OSTI)

A persistent spectral-hole-burning (PSHB) phenomenon was successfully applied to the precise site-selective spectroscopy of CuCl quantum dots embedded in NaCl crystals. In the PSHB spectra of CuCl quantum dots, a resonantly burned hole and lower-energy satellite holes were observed. These satellite holes are supposed to originate from hole burning of the ground states, which results from site-selective excitation of the corresponding excited states of excitons confined in CuCl quantum dots. Energy relation between the resonantly burned hole and each satellite hole is well explained by the simple concept of a particle in a quantum cube with an infinitely high potential barrier. However, actual quantum dots are considered to be a little deviated from cubes, resulting in the violation of the optical selection rule in quantum cubes. A cubic-shaped quantum-dot model is almost consistent with oscillatory fine structures observed in the Z3 exciton absorption band. Its spectral decomposition into the ground state and the first excited state of excitons was made, and showed that the first excited state is in majority at the higher-energy region of the Z3 exciton absorption band. This result was supported by the photoluminescence spectrum of the Z3 exciton.

Burning of coal waste piles from Douro Coalfield (Portugal): Petrological, geochemical and mineralogical characterization  

Science Journals Connector (OSTI)

In the Douro Coalfield anthracites were exploited for decades (17951994). Besides many small mines Douro Coalfield had two principal mining areas (S. Pedro da Cova and Pejo). Coal mining activities cause several impacts on the environment, one of which is the amount of discard or waste which was disposed of all over Douro Coalfield resulting in one of the most significant and severe impacts on the environment. Over 20 waste piles exist in the old mining areas, geographically dispersed, and three of them are presently burning. Their ignition was caused by forest fires during the summer of 2005. Samples from the burning and unburned zones of the waste piles were studied as were the gas from vents and the minerals resulting after combustion. Geochemical processes and mineralogical transformations in the burning coal waste pile were investigated. Microscopic analyses of the samples identified some particular aspects related with combustion: oxidation of pyrite, the presence of iron oxides, organic particles with cracks and rims with lowered (suppressed) Rr, devolatilization vacuoles and some char structures. The occurrence of vitreous (glassy) material as well as FeAl spinels in the burning coal waste provide evidences that the combustion temperature could have reached values above 1000C. Due to combustion, and as expected, the samples studied reported high ash yields. Samples taken from the burning zones reported an increase of As, Cr, Li, Nb, Ni, Pb, Rb, Sr and LREE concentrations and a decrease in Zr and HREE concentrations. Enrichment in Cs, Li and Rb was noted when comparing with the geochemical composition of black shales and world coals composition that is related with the contribution of granitic rocks in the sediments that originated the main lithologies of the Douro Coalfield (carbonaceous shale and lithic arenites). Cluster analyses (R-type and Q-type) were performed to understand the trend between the unburned and burning samples and it seems that some chemical variations are responsible for this separation. Elemental sulphur and salammoniac (ammonium salt) are the coal fire gas minerals neoformed on the surface of piles, near the burning zones. They were identified by different techniques, mainly SEM-EDX, XRD and FTIR. Relatively high concentrations of several aromatic compounds were detected in the gas collected at the studied areas, as well as aliphatic hydrocarbons. The highest concentrations of aromatic hydrocarbons were measured in gas samples from S. Pedro da Cova waste pile. The exposure to hazardous compounds present in the gas is a serious risk to human health and the environment.

Data summary of municipal solid waste management alternatives. Volume 3, Appendix A: Mass burn technologies  

SciTech Connect (OSTI)

This appendix on Mass Burn Technologies is the first in a series designed to identify, describe and assess the suitability of several currently or potentially available generic technologies for the management of municipal solid waste (MSW). These appendices, which cover eight core thermoconversion, bioconversion and recycling technologies, reflect public domain information gathered from many sources. Representative sources include: professional journal articles, conference proceedings, selected municipality solid waste management plans and subscription technology data bases. The information presented is intended to serve as background information that will facilitate the preparation of the technoeconomic and life cycle mass, energy and environmental analyses that are being developed for each of the technologies. Mass burn has been and continues to be the predominant technology in Europe for the management of MSW. In the United States, the majority of the existing waste-to-energy projects utilize this technology and nearly 90 percent of all currently planned facilities have selected mass burn systems. Mass burning generally refers to the direct feeding and combustion of municipal solid waste in a furnace without any significant waste preprocessing. The only materials typically removed from the waste stream prior to combustion are large bulky objects and potentially hazardous or undesirable wastes. The technology has evolved over the last 100 or so years from simple incineration to the most highly developed and commercially proven process available for both reducing the volume of MSW and for recovering energy in the forms of steam and electricity. In general, mass burn plants are considered to operate reliably with high availability.

Analysis of the Three Mile Island Unit 2 hydrogen burn. Volume 4  

SciTech Connect (OSTI)

As a basis for the analysis of the hydrogen burn which occurred in the Three Mile Island Containment on March 28, 1979, a study of recorded temperatures and pressures was made. Long-term temperature information was obtained from the multipoint temperature recorder which shows 12 containment atmosphere temperatures plotted every 6 min. The containment atmosphere pressure recorder provided excellent long- and short-term pressure information. Short-term information was obtained from the multiplex record of 24 channels of data, recorded every 3 sec, and the alarm printer record which shows status change events and prints out temperatures, pressures, and the time of the events. The timing of these four data recording systems was correlated and pertinent data were tabulated, analyzed, and plotted to show average containment temperature and pressure versus time. Photographs and videotapes of the containment entries provided qualitative burn information.

Thermonuclear Burning Regimes and the Use of SNe Ia in Cosmology  

E-Print Network [OSTI]

The calculations of the light curves of thermonuclear supernovae are carried out by a method of multi-group radiation hydrodynamics. The effects of spectral lines and expansion opacity are taken into account. The predictions for UBVI fluxes are given. The values of rise time for B and V bands found in our calculations are in good agreement with the observed values. We explain why our results for the rise time have more solid physical justification than those obtained by other authors. It is shown that small variations in the chemical composition of the ejecta, produced in the explosions with different regimes of nuclear burning, can influence drastically the light curve decline in the B band and, to a lesser extent, in the V band. We argue that recent results on positive cosmological constant Lambda, found from the high redshift supernova observations, could be wrong in the case of possible variations of the preferred mode of nuclear burning in the earlier Universe.

Reductive burning of high-yield spent pulping liquors by the addition of pulverized coal  

SciTech Connect (OSTI)

This paper reports on the reductive burning of high-yield spent pulping liquors which can be accomplished by the addition of pulverized coal to increase the heat content and generate the proper reducing conditions. Samples from a 78%-yield sodium bisulfite pulping process employing a hardwood furnish were mixed with 10-50% pulveriized coal and burned at 950[degrees]C under reducing conditions in a box furnace. Even in these uncontrolled combustion conditions 76. 5% of the sulfur found in the soluble portion of the smelt was converted from lignousulfonates to useful sulfide ion. For the remainder of the sulfur, analyses determined it to be 19. 5% as sulfite ion, 3. 1% as thiosulfate ion, and 0.9% as sulfate ion.

ADVANCED BURNING STAGES AND FATE OF 8-10 M{sub Sun} STARS  

SciTech Connect (OSTI)

The stellar mass range 8 {approx}< M/M{sub Sun} {approx}< 12 corresponds to the most massive asymptotic giant branch (AGB) stars and the most numerous massive stars. It is host to a variety of supernova (SN) progenitors and is therefore very important for galactic chemical evolution and stellar population studies. In this paper, we study the transition from super-AGB (SAGB) star to massive star and find that a propagating neon-oxygen-burning shell is common to both the most massive electron capture supernova (EC-SN) progenitors and the lowest mass iron-core-collapse supernova (FeCCSN) progenitors. Of the models that ignite neon-burning off-center, the 9.5 M{sub Sun} star would evolve to an FeCCSN after the neon-burning shell propagates to the center, as in previous studies. The neon-burning shell in the 8.8 M{sub Sun} model, however, fails to reach the center as the URCA process and an extended (0.6 M{sub Sun }) region of low Y{sub e} (0.48) in the outer part of the core begin to dominate the late evolution; the model evolves to an EC-SN. This is the first study to follow the most massive EC-SN progenitors to collapse, representing an evolutionary path to EC-SN in addition to that from SAGB stars undergoing thermal pulses (TPs). We also present models of an 8.75 M{sub Sun} SAGB star through its entire TP phase until electron captures on {sup 20}Ne begin at its center and of a 12 M{sub Sun} star up to the iron core collapse. We discuss key uncertainties and how the different pathways to collapse affect the pre-SN structure. Finally, we compare our results to the observed neutron star mass distribution.

The effect of developing nations' municipal waste composition on PCDD/PCDF emissions from open burning  

Science Journals Connector (OSTI)

Abstract Open burning tests of municipal waste from two countries, Mexico and China, showed composition-related differences in emissions of polychlorinated dibenzodioxins and dibenzofurans (PCDDs/PCDFs). Twenty-six burn tests were conducted, comparing results from two laboratory combustion facilities. Waste was shredded to isolate composition-specific effects from those due to random waste orientation. Emissions ranged from 5 to 780ng toxic equivalent/kg carbon burned (ng TEQ (kg Cb)?1) with an average of 140ng TEQ (kg Cb)?1 (stdev=170). The waste from Mexico (17ng TEQ (kg Cb)?1) had a statistically lower average emission factor than waste from China (240ng TEQ (kg Cb)?1. This difference was attributed primarily to waste composition differences, although one time-integrated combustion quality measure, ?CO/?CO2, showed statistical significance between laboratories. However, waste composition differences were far more determinant than which laboratory conducted the tests, illustrated using both statistical techniques and comparison of cross-over samples (wastes tested at both facilities). Comparison of emissions from previous waste combustion tests in Sweden and the U.S.A, showed emission factors within the range of those determined for Mexico and China waste. For laboratory-scale combustion, existing emission factors and test methodologies are generally applicable to both developed and developing countries.

Comparison of nuclear data uncertainty propagation methodologies for PWR burn-up simulations  

E-Print Network [OSTI]

Several methodologies using different levels of approximations have been developed for propagating nuclear data uncertainties in nuclear burn-up simulations. Most methods fall into the two broad classes of Monte Carlo approaches, which are exact apart from statistical uncertainties but require additional computation time, and first order perturbation theory approaches, which are efficient for not too large numbers of considered response functions but only applicable for sufficiently small nuclear data uncertainties. Some methods neglect isotopic composition uncertainties induced by the depletion steps of the simulations, others neglect neutron flux uncertainties, and the accuracy of a given approximation is often very hard to quantify. In order to get a better sense of the impact of different approximations, this work aims to compare results obtained based on different approximate methodologies with an exact method, namely the NUDUNA Monte Carlo based approach developed by AREVA GmbH. In addition, the impact of different covariance data is studied by comparing two of the presently most complete nuclear data covariance libraries (ENDF/B-VII.1 and SCALE 6.0), which reveals a high dependency of the uncertainty estimates on the source of covariance data. The burn-up benchmark Exercise I-1b proposed by the OECD expert group "Benchmarks for Uncertainty Analysis in Modeling (UAM) for the Design, Operation and Safety Analysis of LWRs" is studied as an example application. The burn-up simulations are performed with the SCALE 6.0 tool suite.

Case Study of Water-Soluble Metal Containing Organic Constituents of Biomass Burning Aerosol  

SciTech Connect (OSTI)

Natural and prescribed biomass fires are a major source of atmospheric aerosols that can persist in the atmosphere for long periods of time. Biomass burning aerosols (BBA) can be associated with long range transport of water soluble N?, S?, P?, and metal?containing species. In this study, BBA samples were collected using a particle?into?liquid sampler (PILS) from laboratory burns of vegetation collected on military bases in the southeastern and southwestern United States. The samples were then analyzed using high resolution electrospray ionization mass spectrometry (ESI/HR?MS) that enabled accurate mass measurements for hundreds of species with m/z values between 70 and 1000 and assignment of probable elemental formulae. Mg, Al, Ca, Cr, Mn, Fe, Ni, Cu, Zn, and Ba?containing organometallic species were identified. The results suggest that the biomass may have accumulated metal?containing species that were reemitted during biomass burning. Further research into the sources, persistence, and dispersion of metal?containing aerosols as well as their environmental effects is needed.

Quantitative IR Spectrum and Vibrational Assignments for Glycolaldehyde Vapor: Glycolaldehyde Measurements in Biomass Burning Plumes  

SciTech Connect (OSTI)

Glycolaldehyde (GA, 2-hydroxyethanal, C2H4O2) is a semi-volatile molecule of atmospheric importance, recently proposed as a precursor in the formation of aqueous-phase secondary organic aerosol (SOA). There are few methods to measure glycolaldehyde vapor, but infrared spectroscopy has been used successfully. Using vetted protocols we have completed the first assignment of all fundamental vibrational modes and derived quantitative IR absorption band strengths using both neat and pressure-broadened GA vapor. Even though GA is problematic due to its propensity to both dimerize and condense, our intensities agree well with the few previously published values. Using the reference ?10 band Q-branch at 860.51 cm-1, we have also determined GA mixing ratios in biomass burning plumes generated by field and laboratory burns of fuels from the southeastern and southwestern United States, including the first field measurements of glycolaldehyde in smoke. The GA emission factors were anti-correlated with modified combustion efficiency confirming release of GA from smoldering combustion. The GA emission factors (g of GA emitted per kg dry biomass burned on a dry mass basis) had a low dependence on fuel type consistent with the production mechanism being pyrolysis of cellulose. GA was emitted at 0.23 0.13% of CO from field fires and we calculate that it accounts for ~18% of the aqueous-phase SOA precursors that we were able to measure.

Organic Rankine Cycle System Preliminary Design with Corn Cob Biomass Waste Burning as Heat Source  

Science Journals Connector (OSTI)

Abstract The renewable energy source potencies in Indonesia are needed to be utilized to fulfill the electricity requirement in rural or remote area that not yet get electricity. One of the potency is biomass waste. Therefore, this paper discusses about the electricity generation preliminary design of Organic Rankine Cycle (ORC) system with corn cob biomass waste burning as heat source, so it can be obtained the theoretic corn farm area requirement, electricity power, and thermal efficiency at heat source temperature and flow rate variations. Corn cob burning temperature can heat up the heating fluid that is heated by boiler with corn cob as the biomass fuel. Furthermore, that heating fluid is used as ORC electricity generation heat source. The independent variables in this study are the heating fluid temperature which varied between 110, 120, and 130oC, and the heating fluid flow rate that varied between 100, 150, and 200 liter/minute. \\{R141b\\} is selected to be the working fluid, palm oil is used for heating fluid and water as cooling fluid. The calculation results that the theoretic electricity power, thermal efficiency, and corn farm area requirement, respectively, are in the range of 3.5-8.5kW, 9.2-10.3%, and 49.5-101.1hectare/year. All of the highest range values are resulted at the highest temperature and flow rate, 130oC and 200 liter/minute. This result shows that corn cob burning heat is potential to be utilized as electricity generation heat source for rural society, particularly for some areas that have been studied.

Oxidation of volatiles in residential wood burning equipment. Final technical report, September 1980-February 1984  

SciTech Connect (OSTI)

The objectives of this project are to measure, through the use of laboratory combustors, those conditions which promote complete combustion of wood volatiles in residential wood burning equipment. The conditions of interest are combustion temperature, residence time, stoichiometry, and air mixing. The project objectives are met through two laboratory approaches: (1) model compound studies: in order to measure the overall rates of oxidative pyrolysis of biomass volatiles, and to determine the types of intermediate organic species which are likely to form as part of this process, model compounds have been reacted in a specialized jet-stirred reactor, which has been developed as part of this research. (2) high-intensity wood combustion: in order to study the clean combustion of wood, that is, to investigate the conceptual design features required for clean burning, and to ascertain the levels and types of pollutant and condensible species which are most difficult to oxidize, a high-intensity, research wood combustor has been developed and examined for the different phases of the wood burning cycle. Although the objectives of the project have been met, it has not been possible, because of support limitations, to thoroughly explore several interesting aspects which have arisen because of this research. For example, a third laboratory system in which wood pyrolysis gas is injected directly into the a well characterized reactor, so that the kinetics and mechanisms of the gas-phase reaction of the actual biomass volatiles can be studied, could not be thoroughly developed. Refinements in the high-intensity wood combustor, which would bring its design features closer to practicality for the industry, could not be considered. 32 references, 37 figures, 10 tables.

An experimental investigation was conducted on the combustion characteristics of droplets of n-heptane, n-decane, n-dodecane, n-hexadecane and iso-octane emulsified with various amount of water and freely falling in a furnace of controlled temperature. Results demonstrate the intricate influences of water emulsification on the ignition, extinction and micro-explosion of the droplet response, and that the droplet burning time can be significantly reduced through judicious fuel blending so as to minimize the ignition delay and advance the onset of micro-explosion.

Experimental observation of carbon dioxide reduction in exhaust gas from hydrocarbon fuel burning  

Science Journals Connector (OSTI)

A high-negative voltage at the cathode initiates a dark discharge resulting in a reduction of the carbon dioxide concentration in exhaust gas from the burning of hydrocarbon fuel. An experiment indicated that nearly 44% of the carbon dioxide in exhaust gas disappears after a high-voltage application to the cathode. The energy needed for the endothermic reaction of the carbon dioxidedissociation corresponding to this concentration reduction is provided mainly by the internal energy reduction of the discharge gas which is nearly 20 times the electrical energy for electron emission.

Transuranic Waste Burning Potential of Thorium Fuel in a Fast Reactor - 12423  

SciTech Connect (OSTI)

Westinghouse Electric Company (referred to as 'Westinghouse' in the rest of this paper) is proposing a 'back-to-front' approach to overcome the stalemate on nuclear waste management in the US. In this approach, requirements to further the societal acceptance of nuclear waste are such that the ultimate health hazard resulting from the waste package is 'as low as reasonably achievable'. Societal acceptability of nuclear waste can be enhanced by reducing the long-term radiotoxicity of the waste, which is currently driven primarily by the protracted radiotoxicity of the transuranic (TRU) isotopes. Therefore, a transition to a more benign radioactive waste can be accomplished by a fuel cycle capable of consuming the stockpile of TRU 'legacy' waste contained in the LWR Used Nuclear Fuel (UNF) while generating waste which is significantly less radio-toxic than that produced by the current open U-based fuel cycle (once through and variations thereof). Investigation of a fast reactor (FR) operating on a thorium-based fuel cycle, as opposed to the traditional uranium-based is performed. Due to a combination between its neutronic properties and its low position in the actinide chain, thorium not only burns the legacy TRU waste, but it does so with a minimal production of 'new' TRUs. The effectiveness of a thorium-based fast reactor to burn legacy TRU and its flexibility to incorporate various fuels and recycle schemes according to the evolving needs of the transmutation scenario have been investigated. Specifically, the potential for a high TRU burning rate, high U-233 generation rate if so desired and low concurrent production of TRU have been used as metrics for the examined cycles. Core physics simulations of a fast reactor core running on thorium-based fuels and burning an external TRU feed supply have been carried out over multiple cycles of irradiation, separation and reprocessing. The TRU burning capability as well as the core isotopic content have been characterized. Results will be presented showing the potential for thorium to reach a high TRU transmutation rate over a wide variety of fuel types (oxide, metal, nitride and carbide) and transmutation schemes (recycle or partition of in-bred U-233). In addition, a sustainable scheme has been devised to burn the TRU accumulated in the core inventory once the legacy TRU supply has been exhausted, thereby achieving long-term virtually TRU-free. A comprehensive 'back-to-front' approach to the fuel cycle has recently been proposed by Westinghouse which emphasizes achieving 'acceptable', low-radiotoxicity, high-level waste, with the intent not only to satisfy all technical constraints but also to improve public acceptance of nuclear energy. Following this approach, the thorium fuel cycle, due to its low radiotoxicity and high potential for TRU transmutation has been selected as a promising solution. Additional studies not shown here have shown significant reduction of decay heat. The TRU burning potential of the Th-based fuel cycle has been illustrated with a variety of fuel types, using the Toshiba ARR to perform the analysis, including scenarios with continued LWR operation of either uranium fueled or thorium fueled LWRs. These scenarios will afford overall reduction in actinide radiotoxicity, however when the TRU supply is exhausted, a continued U- 235 LWR operation must be assumed to provide TRU makeup feed. This scenario will never reach the characteristically low TRU content of a closed thorium fuel cycle with its associated potential benefits on waste radiotoxicity, as exemplified by the transition scenario studied. At present, the cases studied indicate ThC as a potential fuel for maximizing TRU burning, while ThN with nitrogen enriched to 95% N-15 shows the highest breeding potential. As a result, a transition scenario with ThN was developed to show that a sustainable, closed Th-cycle can be achieved starting from burning the legacy TRU stock and completing the transmutation of the residual TRU remaining in the core inventory after the legacy TRU external supply has been

Method of burning sulfur-containing fuels in a fluidized bed boiler  

DOE Patents [OSTI]

A method of burning a sulfur-containing fuel in a fluidized bed of sulfur oxide sorbent wherein the overall utilization of sulfur oxide sorbent is increased by comminuting the bed drain solids to a smaller average particle size, preferably on the order of 50 microns, and reinjecting the comminuted bed drain solids into the bed. In comminuting the bed drain solids, particles of spent sulfur sorbent contained therein are fractured thereby exposing unreacted sorbent surface. Upon reinjecting the comminuted bed drain solids into the bed, the newly-exposed unreacted sorbent surface is available for sulfur oxide sorption, thereby increasing overall sorbent utilization.

On the Stability of Thermonuclear Burning Fronts in Type Ia Supernovae  

E-Print Network [OSTI]

The propagation of cellularly stabilized thermonuclear flames is investigated by means of numerical simulations. In Type Ia supernova explosions the corresponding burning regime establishes at scales below the Gibson length. The cellular flame stabilization - which is a result of an interplay between the Landau-Darrieus instability and a nonlinear stabilization mechanism - is studied for the case of propagation into quiescent fuel as well as interaction with vortical fuel flows. Our simulations indicate that in thermonuclear supernova explosions stable cellular flames develop around the Gibson scale and that deflagration-to-detonation transition is unlikely to be triggered from flame evolution effects here.

A New View of the Cosmic Landscape  

E-Print Network [OSTI]

In this scenario, a generic meta-stable deSitter vacuum site in the cosmic landscape in string theory has a very short lifetime. Typically, the smaller is the vacuum energy of a meta-stable site, the longer is its lifetime. This view of the landscape can provide a qualitative dynamical explanation why the dark energy of our universe is so small. The argument for this scenario is based on resonance tunneling, a well-known quantum mechanical phenomenon, the topography of the landscape, and the vastness of the cosmic landscape. Mapping the topography of the landscape, even if only in a small region, will test the validity of this scenario.

Spectral hole burnings in spontaneous emission spectra from 1.3 ..mu..m InGaAsP lasers were found. The results are understood on the basis of population burnings of holes associated with the saturation of intervalence-band absorption. Theoretical results on hot carrier relaxation are shown to explain the population burnings, pointing out an importance of nonequilibrium optical phonon populations in the active layers of long wavelength InGaAsP lasers and light emitting diodes (LED's).

Numerical and experimental study on laminar burning velocity of syngas produced from biomass gasification in sub-atmospheric pressures  

Science Journals Connector (OSTI)

Abstract The laminar burning velocity of syngas mixtures has been studied by various researches. However, most of these studies have been conducted in atmospheric conditions at sea level. In the present study, the effect of sub atmospheric pressure was evaluated on the laminar burning velocity for a mixture of H2, CO and N2 (20:20:60vol%) in real sub atmospheric condition. The measurements was conducted in an altitude of 2130m.a.s.l (0.766atm) and 21m.a.s.l (0.994atm) to evaluate the effect of pressure, the temperature and relative humidity were controlled using an air conditioning unit and was maintained in 2951K and 62.62.7% respectively. The Flames were generated using contoured slot-type nozzle burner, and an ICCD camera was used to capture chemiluminescence emitted by OH?-CH? radicals present in the flame and thus obtain the flame front and determinate the laminar burning velocity using the angle method. The experimental results were compared with numerical calculations, conducted using the detailed mechanisms of Li etal. and the GRI-Mech 3.0. It was found that the laminar burning velocity increases at lower pressure, for an equivalence ratio of 1.1, the laminar burning velocity increases by almost 23% respect to the sea level conditions.

Deep sole burns in several participants in a traditional festival of the firewalking ceremony in Kee-lung, TaiwanClinical experiences and prevention strategies  

Science Journals Connector (OSTI)

Purpose Firewalking is a common Taoist cleansing ceremony in Taiwan, but burns associated with the practice have rarely been reported. We analyzed the patients with plantar burns from one firewalking ceremony. Materials and methods In one firewalking ceremony, 12 Taoist disciples suffered from contact burns to the soles of their feet while walking over burning coals. Eight of them had at least second-degree burns over areas larger than 1% of their total body surface areas (TBSAs). The age, sex, medical history, date of injury, time taken to traverse the fire pit, depth and TBSA of the burns, treatment, length of stay, and outcome were recorded and analyzed. Results Deep, disseminated second- to third-degree burns were noted and healing took as long as three weeks in some patients. Because disseminated hypertrophic scars form after burns, the soles involved regain much of their tensile strength while walking. The patients experienced only a few difficulties in their daily lives three months after injury. Conclusion From our experience treating patients with deep disseminated second- to third-degree plantar burns caused by firewalking, we conclude that they should be treated conservatively, with secondary healing rather than a skin graft.

Carbon nanotube (CNT) gas sensors for emissions from fossil fuel burning  

Science Journals Connector (OSTI)

Abstract Fossil fuels endow wide applications in industrial, transportation, and power generation sectors. However, smoke released by burning fossil fuels contains toxic gases, which pollutes the environment and severely affects human health. Carbon nanotubes (CNTs) are potential material for gas sensors due to their high structural porosity and high specific surface area. Defects present on the CNT sidewalls and end caps facilitate adsorption of gas molecules. The chemical procedures adopted to purify and disperse carbon nanotubes create various chemical groups on their surface, which further enhance the adsorption of gas molecules and thus improve the sensitivity of CNTs. Present review focuses on CNT chemiresistive gas sensing mechanisms, which make them suitable for the development of next generation sensor technology. The resistance of carbon nanotubes decreases when oxidizing gas molecules adsorb on their surface, whereas, adsorption of reducing gas molecules results in increasing the resistance of CNTs. Sensing ability of carbon nanotubes for the gases namely, NO, NO2, CO, CO2 and SO2, released on burning of fossil fuels is reviewed. This review provides basic understanding of sensing mechanisms, creation of adsorption sites by chemical processes and charge transfer between adsorbed gas molecules and surface of CNTs. In addition, useful current update on research and development of CNT gas sensors is provided.

Emissions of unintentional persistent organic pollutants from open burning of municipal solid waste from developing countries  

Science Journals Connector (OSTI)

Open burning of waste is the most significant source of polychlorinated dibenzo-para-dioxins and dibenzofurans (PCDD/PCDF) in many national inventories prepared pursuant to the Stockholm Convention on Persistent Organic Pollutants. This is particularly true for developing countries. Emission factors for \\{POPs\\} such as PCDD/PCDF, dioxin-like polychlorinated biphenyls (dl-PCB) and penta- and hexachlorobenzenes (PeCBz/HCB) from open burning of municipal solid waste in China and Mexico are reported herein. Six different waste sources were studied varying from urban-industrial to semi-urban to rural. For PCDD/PCDF, the emission factors to air ranged from 3.0 to 650ngTEQkg?1waste and for dl-PCB from 0.092 to 54ngTEQkg?1waste. Emission factors for PeCBz (171200ngkg?1waste) and HCB (241300ngkg?1waste) spanned a wide but similar range. Within the datasets there is no indication of significant waste composition effect on emission factor with the exception of significantly higher Mexico rural samples.

Geophysical investigation of burn pit, 128-H-1, 100-H Area  

SciTech Connect (OSTI)

The 128-H-1 burn pit is located in the northeast corner of 100-H Area. The objective of the survey was to delineate subsurface features in the 128-H-1 burn pit that may affect the emplacement of soil-gas probes. Ground-penetrating radar (GPR) and electromagnetic induction (EMI) were the two techniques used in the investigation. The methods were selected because they are non-intrusive, relatively fast, economical, and have been used successfully in other geophysical investigations on the Hanford Site. The GPR system used for this work utilized a 300-MHz antenna to transmit the Em energy into the ground. The transmitted energy is reflected back to a receiving antenna where variations in the return signal are recorded. Common reflectors include natural geologic conditions such as bedding, cementation, moisture, and clay, or man-made objects such as pipes, barrels, foundations, and buried wires. The studied depth, which varies from site to site, was 0--11 ft for this survey. The method is limited in depth by transmit power, receiver sensitivity, and attenuation of the transmitted energy. Depth of investigation is influenced by highly conductive material, such as metal drums, which reflect all the energy back to the receiver. Therefore, the method cannot ``see`` below such objects.

Stress Analysis of Coated Particle Fuel in the Deep-Burn Pebble Bed Reactor Design  

SciTech Connect (OSTI)

High fuel temperatures and resulting fuel particle coating stresses can be expected in a Pu and minor actinide fueled Pebble Bed Modular Reactor (400 MWth) design as compared to the standard UO2 fueled core. The high discharge burnup aimed for in this Deep-Burn design results in increased power and temperature peaking in the pebble bed near the inner and outer reflector. Furthermore, the pebble power in a multi-pass in-core pebble recycling scheme is relatively high for pebbles that make their first core pass. This might result in an increase of the mechanical failure of the coatings, which serve as the containment of radioactive fission products in the PBMR design. To investigate the integrity of the particle fuel coatings as a function of the irradiation time (i.e. burnup), core position and during a Loss Of Forced Cooling (LOFC) incident the PArticle STress Analysis code (PASTA) has been coupled to the PEBBED code for neutronics, thermal-hydraulics and depletion analysis of the core. Two deep burn fuel types (Pu with or without initial MA fuel content) have been investigated with the new code system for normal and transient conditions including the effect of the statistical variation of thickness of the coating layers.

R and D of Oxide Dispersion Strengthening Steels for High Burn-up Fuel Claddings  

SciTech Connect (OSTI)

Research and development of fuel clad materials for high burn-up operation of light water reactor and super critical water reactor (SCPWR) will be shown with focusing on the effort to overcome the requirements of material performance as the fuel clad. Oxide dispersion strengthening (ODS) steels are well known as a high temperature structural material. Recent irradiation experiments indicated that the steels were quite highly resistant to neutron irradiation embrittlement, showing hardening without accompanying loss of ductility. High Cr ODS steels whose chromium concentration was in the range from 15 to 19 wt% showed high resistance to corrosion in supercritical pressurized water (SCPW). As for the susceptibility to hydrogen embrittlement of ODS steels, the critical hydrogen concentration required to hydrogen embrittlement is ranging 10{approx}12 wppm that is approximately one order of magnitude higher value than that of 9Cr reduced activation ferritic (RAF) steel. In the ODS steels, the fraction of helium desorption by bubble migration mechanism was smaller than that in the RAF steel, indicating that the ODS steels are also resistant to helium He bubble-induced embrittlement. Finally, it is demonstrated that the ODS steels are very promising for the fuel clad material for high burn-up operation of water-cooling reactors. (authors)

Thermonuclear Burning on the Accreting X-Ray Pulsar GRO J1744-28  

E-Print Network [OSTI]

We investigate the thermal stability of nuclear burning on the accreting X-ray pulsar GRO J1744-28. The neutron star's dipolar magnetic field is thermonuclear instabilities are unlikely causes of the hourly bursts seen at very high accretion rates. We then discuss how the stability of the thermonuclear burning depends on both the global accretion rate and the neutron star's magnetic field strength. We emphasize that the appearance of the instability (i.e., whether it looks like a Type I X-ray burst or a flare lasting a few minutes) will yield crucial information on the neutron star's surface magnetic field and the role of magnetic fields in convection. We suggest that a thermal instability in the accretion disk is the origin of the long (~300 days) outburst and that the recurrence time of these outbursts is >50 years. We also discuss the nature of the binary and point out that a velocity measurement of the stellar companion (most likely a Roche-lobe filling giant with m_K>17) will constrain the neutron star mass.

On the Effect of Explosive Thermonuclear Burning on the Accreted Envelopes of White Dwarfs in Cataclysmic Variables  

Science Journals Connector (OSTI)

The detection of heavy elements at suprasolar abundances in the atmospheres of some accreting white dwarfs in cataclysmic variables (CVs), coupled with the high temperatures needed to produce these elements, requires explosive thermonuclear burning. The central temperatures of any formerly more massive secondary stars in CVs undergoing hydrostatic CNO burning are far too low to produce these elements. Evidence is presented that at least some CVs contain donor secondaries that have been contaminated by white dwarf remnant burning during the common envelope phase and are transferring this material back to the white dwarf. This scenario does not exclude the channel in which formerly more massive donor stars underwent CNO processing in systems with thermal timescale mass transfer. Implications for the progenitors of CVs are discussed and a new scenario for the white dwarf's accretion-nova-outburst is given.

SciTech Connect (OSTI)

To assess any impact on the environment resulting from operations at the High Explosives (HE) Burn Pits at Lawrence Livermore National Laboratory (LLNL) Site 300, we evaluated the soil, rock, and ground water beneath the burn pit facility. Between November 16, 1986, and January 12, 1987, we drilled eight exploratory holes; one was converted to a monitor well, and another was converted to a piezometer. Seven holes were drilled, geologically logged, and sampled to determine the concentration and extent of substances that may have infiltrated to the subsurface from the burn pits. The eighth hole was completed as a monitor well but was not sampled, and no detailed log was prepared. Electric logging was performed in one exploratory hole further evaluate the geologic conditions. 27 refs., 4 figs., 6 tabs.

Epoxy-borax-coal tar composition for a radiation protective, burn resistant drum liner and centrifugal casting method  

DOE Patents [OSTI]

A boron containing burn resistant, low level radiation protection material useful, for example, as a liner for radioactive waste disposal and storage, a component for neutron absorber, and a shield for a neutron source. The material is basically composed of Borax in the range of 25-50%, coal tar in the range of 25-37.5%, with the remainder being an epoxy resin mix. A preferred composition is 50% Borax, 25% coal tar and 25% epoxy resin. The material is not susceptible to burning and is about 1/5 the cost of existing radiation protection material utilized in similar applications.

SciTech Connect (OSTI)

The 128-F-3 waste site is a former burn pit associated with the 100-F Area experimental animal farm. The site was overlain by coal ash associated with the 126-F-1 waste site and could not be located during confirmatory site evaluation. Therefore, a housekeeping action was performed to remove the coal ash potentially obscuring residual burn pit features. The results of verification sampling demonstrated that residual contaminant concentrations do not preclude any future uses and allow for unrestricted use of shallow zone soils. The results also showed that residual contaminant concentrations are protective of groundwater and the Columbia River.

Investigation of the behaviour of high burn-up PWR fuel under RIA conditions in the CABRI test reactor  

SciTech Connect (OSTI)

Performance, reliability and economics are the goal criteria for fuel pin design and development. For steady state behaviour and operational transients, the demonstration is made worldwide that burn-up of more than 60 GWd/t can be reached reliably with improved PWR fuel. It has however not been demonstrated yet that safety criteria, related to design basis accident scenarios, are still respected at these high burn-up levels. In particular, for the reactivity initiated accident (RIA), resulting from a postulated, rapid removal of control rod elements, the amount of energy injection must be limited by design such that no severe damage to the core and its structures might occur.

Study advances view of geopressure seals  

SciTech Connect (OSTI)

The last decade has seen a growing interest in the subject of fluid pressure seals and fluid flow in hydrocarbon-bearing basins. As explorationists begin to view basins in terms of coupled, dynamic, chemical, and physical processes, seemingly unrelated observations become interrelated. It is precisely the integration of geological, geochemical, and geophysical observations that opens the door for new exploration opportunities. This article lays a conceptual foundation in the area of geopressure seals and on the role of geopressure in hydrocarbon migration and accumulation in young, clastic basins. The exploration significance of geopressure can be appreciated when one considers that within the gulf Coast basin, geopressured fields, which represent only 10% of the total number of fields, account for approximately 50% of the cumulative production.

Direct and semidirect aerosol effects of Southern African biomass burning aerosol  

SciTech Connect (OSTI)

The direct and semi-direct radiative effects of biomass burning aerosols from Southern African fires during July-October are investigated using 20 year runs of the Community Atmospheric Model (CAM) coupled to a slab ocean model. The aerosol optical depth is constrained using observations in clear skies from MODIS and for aerosol layers above clouds from CALIPSO. Over the ocean, where the absorbing biomass burning aerosol layers are primarily located above cloud, negative top of atmosphere (TOA) semi-direct radiative effects associated with increased low cloud cover dominate over a weaker positive all-sky direct radiative effect (DRE). In contrast, over the land where the aerosols are often below or within cloud layers, reductions in cloud liquid water path (LWP) lead to a positive semi-direct radiative effect that dominates over a near-zero DRE. Over the ocean, the cloud response can be understood as a response to increased lower tropospheric stability (LTS) which is caused both by aerosol absorptive warming in overlying layers and surface cooling in response to direct aerosol forcing. The ocean cloud changes are robust to changes in the cloud parameterization (removal of the hard-wired dependence of clouds on LTS), suggesting that they are physically realistic. Over land where cloud cover changes are minimal, decreased LWP is consistent with weaker convection driven by increased static stability. Over the entire region the overall TOA radiative effect from the biomass burning aerosols is almost zero due to opposing effects over the land and ocean. However, the surface forcing is strongly negative requiring a reduction in precipitation. This is primarily realized through reductions in convective precipitation on both the southern and northern flanks of the convective precipitation region spanning the equatorial rainforest and the ITCZ in the southern Sahel. The changes are consistent with the low-level aerosol forced cooling pattern. The results highlight the importance of semi-direct radiative effects and precipitation responses for determining the climatic effects of aerosols in the African region.

Urban air quality improvement by using a CNG lean burn engine for city buses  

Science Journals Connector (OSTI)

The use of compressed natural gas (CNG)-fuelled lean-burn city bus engines has a significant potential for air quality improvement in urban areas. Particularly important is the reduction of NOx, as well as particulate and non-regulated HC-emissions. For this reason, a CNG-fuelled, lean-bum, turbocharged, intercooled engine equipped with catalytic converter was developed. The basic engine is a 6-cylinder, heavy duty, serial production Hungarian diesel engine which complies with Euro-2 emissions limits. The objective of this development was to meet European emission limits forecast for the year 2005 (NOx fuel consumption capability of the engine are reported. Based on the evaluation of economical feasibility, the costs of CNG bus operation is additionally discussed. It can be concluded that CNG city bus operation is - compared to diesel operation - a promising way to improve economically the local air quality.

Transmutation Analysis of Enriched Uranium and Deep Burn High Temperature Reactors  

SciTech Connect (OSTI)

High temperature reactors (HTRs) have been under consideration for production of electricity, process heat, and for destruction of transuranics for decades. As part of the transmutation analysis efforts within the Fuel Cycle Research and Development (FCR&D) campaign, a need was identified for detailed discharge isotopics from HTRs for use in the VISION code. A conventional HTR using enriched uranium in UCO fuel was modeled having discharge burnup of 120 GWd/MTiHM. Also, a deep burn HTR (DB-HTR) was modeled burning transuranic (TRU)-only TRU-O2 fuel to a discharge burnup of 648 GWd/MTiHM. For each of these cases, unit cell depletion calculations were performed with SCALE/TRITON. Unit cells were used to perform this analysis using SCALE 6.1. Because of the long mean free paths (and migration lengths) of neutrons in HTRs, using a unit cell to represent a whole core can be non-trivial. The sizes of these cells were first set by using Serpent calculations to match a spectral index between unit cell and whole core domains. In the case of the DB-HTR, the unit cell which was arrived at in this way conserved the ratio of fuel to moderator found in a single block of fuel. In the conventional HTR case, a larger moderator-to-fuel ratio than that of a single block was needed to simulate the whole core spectrum. Discharge isotopics (for 500 nuclides) and one-group cross-sections (for 1022 nuclides) were delivered to the transmutation analysis team. This report provides documentation for these calculations. In addition to the discharge isotopics, one-group cross-sections were provided for the full list of 1022 nuclides tracked in the transmutation library.

View Discovery in OLAP Databases through Statistical Combinatorial Optimization  

SciTech Connect (OSTI)

The capability of OLAP database software systems to handle data complexity comes at a high price for analysts, presenting them a combinatorially vast space of views of a relational database. We respond to the need to deploy technologies sufficient to allow users to guide themselves to areas of local structure by casting the space of ``views'' of an OLAP database as a combinatorial object of all projections and subsets, and ``view discovery'' as an search process over that lattice. We equip the view lattice with statistical information theoretical measures sufficient to support a combinatorial optimization process. We outline ``hop-chaining'' as a particular view discovery algorithm over this object, wherein users are guided across a permutation of the dimensions by searching for successive two-dimensional views, pushing seen dimensions into an increasingly large background filter in a ``spiraling'' search process. We illustrate this work in the context of data cubes recording summary statistics for radiation portal monitors at US ports.

A high-resolution and multi-year emissions inventory for biomass burning in Southeast Asia during 20012010  

Science Journals Connector (OSTI)

Abstract Biomass burning (BB) emissions from forest fires, agricultural waste burning, and peatland combustion contain large amounts of greenhouse gases (e.g., CO2, CH4, and N2O), which significantly impact ecosystem productivity, global atmospheric chemistry, and climate change. With the help of recently released satellite products, biomass density based on satellite and observation data, and spatiotemporal variable combustion factors, this study developed a new high-resolution and multi-year emissions inventory for BB in Southeast Asia (SEA) during 20012010. The 1-km grid was effective for quantifying emissions from small-sized fires that were frequently misinterpreted by coarse grid data due to their large smoothed pixels. The average annual BB emissions in SEA during 20012010 were 277Gg SO2, 1125Gg NOx, 55,388Gg CO, 3831Gg NMVOC, 553Gg NH3, 324Gg BC, 2406Gg OC, 3832Gg CH4, 817,809Gg CO2, and 99Gg N2O. Emissions were high in western Myanmar, Northern Thailand, eastern Cambodia, northern Laos, and South Sumatra and South Kalimantan of Indonesia. Emissions from forest burning were the dominant contributor to the total emissions among all land types. The spatial pattern of BB emissions was consistent with that of the burned areas. In addition, BB emissions exhibited similar temporal trends from 2001 to 2010, with strong interannual and intraannual variability. Interannual and intraannual emission peaks were seen during 2004, 2007, 2010, and JanuaryMarch and AugustOctober, respectively.

A HYPERSPECTRAL VIEW OF THE CRAB NEBULA  

SciTech Connect (OSTI)

We have obtained spatially resolved spectra of the Crab nebula in the spectral ranges 450-520 nm and 650-680 nm, encompassing the H{beta}, [O III] {lambda}4959, {lambda}5007, H{alpha}, [N II] {lambda}6548, {lambda}6584, and [S II] {lambda}6717, {lambda}6731 emission lines, with the imaging Fourier transform spectrometer SpIOMM at the Observatoire du Mont-Megantic's 1.6 m telescope. We first compare our data with published observations obtained either from a Fabry-Perot interferometer or from a long-slit spectrograph. Using a spectral deconvolution technique similar to the one developed by Cadez et al., we identify and resolve multiple emission lines separated by large Doppler shifts and contained within the rapidly expanding filamentary structure of the Crab. This allows us to measure important line ratios, such as [N II]/H{alpha}, [S II]/H{alpha}, and [S II] {lambda}6717 /[S II] {lambda}6731 of individual filaments, providing a new insight on the SE-NW asymmetry in the Crab. From our analysis of the spatial distribution of the electronic density and of the respective shocked versus photoionized gas components, we deduce that the skin-less NW region must have evolved faster than the rest of the nebula. Assuming a very simple expansion model for the ejecta material, our data provide us with a complete tridimensional view of the Crab.

Performance viewing and editing in ASSESS Outsider  

SciTech Connect (OSTI)

The Analytic System and Software for Evaluation of Safeguards and Security (ASSESS) Facility module records site information in the path elements and areas of an Adversary Sequence Diagram. The ASSESS Outsider evaluation module takes this information and first calculates performance values describing how much detection and delay is assigned at each path element and then uses the performance values to determine most-vulnerable paths. This paper discusses new Outsider capabilities that allow the user to view how elements are being defeated and to modify some of these values in Outsider. Outsider now displays how different path element segments are defeated and contrasts the probability of detection for alternate methods of defeating a door (e.g., the lock or the door face itself). The user can also override element segment delays and detection probabilities directly during analysis in Outsider. These capabilities allow users to compare element performance and to verify correct path element performance for all elements, not just those on the most-vulnerable path as is the case currently. Improvements or reductions in protection can be easily checked without creating a set of new facility files to accomplish it.

The INTEGRAL View of the Galactic Nucleus  

E-Print Network [OSTI]

We present the preliminary results of the observational campaign performed in 2003 to study the Galactic Nucleus with INTEGRAL. The mosaicked images obtained with the IBIS/ISGRI coded aperture instrument in the energy range above 20 keV, give a yet unseen view of the high-energy sources of this region in hard X and gamma-rays, with an angular resolution of 12'. We report on the discovery of a source, IGR J17456-2901, compatible with the instrument's point spread function and coincident with the Galactic Nucleus Sgr A* to within 0.9'. The source is visible up to 60-80 keV with a 20-100 keV luminosity at 8 kpc of 3 x 10E35 erg/s. Although we cannot unequivocally associate the new INTEGRAL source to the Galactic Nucleus, this is the first report of significant hard X-ray emission from within the inner 10' of the Galaxy and a contribution from the galactic center supermassive black hole itself cannot be excluded. Here we discuss the results obtained and the perspectives for future observations of the Galactic Nuc...

Nonlinear control and online optimization of the burn condition in ITER via heating, isotopic fueling and impurity injection  

Science Journals Connector (OSTI)

The ITER tokamak, the next experimental step toward the development of nuclear fusion reactors, will explore the burning plasma regime in which the plasma temperature is sustained mostly by fusion heating. Regulation of the fusion power through modulation of fueling and external heating sources, referred to as burn control, is one of the fundamental problems in burning plasma research. Active control will be essential for achieving and maintaining desired operating points, responding to changing power demands, and ensuring stable operation. Most existing burn control efforts use either non-model-based control techniques or designs based on linearized models. These approaches must be designed for particular operating points and break down for large perturbations. In this work, we utilize a spatially averaged (zero-dimensional) nonlinear model to synthesize a multi-variable nonlinear burn control strategy that can reject large perturbations and move between operating points. The controller uses all of the available actuation techniques in tandem to ensure good performance, even if one or more of the actuators saturate. Adaptive parameter estimation is used to improve the model parameter estimates used by the feedback controller in real-time and ensure asymptotic tracking of the desired operating point. In addition, we propose the use of a model-based online optimization algorithm to drive the system to a state that minimizes a given cost function, while respecting input and state constraints. A zero-dimensional simulation study is presented to show the performance of the adaptive control scheme and the optimization scheme with a cost function weighting the fusion power and temperature tracking errors.

FIRE IMPACTS ON AN ENGINEERED BARRIERS PERFORMANCE: THE HANFORD BARRIER ONE YEAR AFTER A CONTROLLED BURN  

SciTech Connect (OSTI)

A critical unknown for long-term engineered barrier performance is the effect of wild fire during a post-institutional control environment where routine maintenance may be limited or non-existent. In September 2008, a controlled burn was conducted on one half of a vegetated, multilayered capillary barrier emplaced over a Hanford waste site. The effects on barrier performance have been monitored and documented over the past year. Soil physical, chemical, and hydrologic properties; plant floristics and density; and animal-use were characterized before and after the fire with the unburned half of the barrier serving as a control. Temperatures during the controlled burn ranged from 250 oC at 1.5 cm below the surface to over 700 oC at 1 m above the surface. Significant decreases in hydraulic conductivity and surface-soil wettability were observed immediately after the fire due primarily to hydrophobic conditions created by the fire. Major soil nutrients, pH, and electrical conductivity remain elevated post-fire. Up until June 2009, post-burn soil moisture content in the 0-1 m depth interval was significantly lower on the burned section than the unburned section and is attributed to differences in surface evaporation. Higher soil moisture contents in the 1-2 m interval on the burned section are attributed to insignificant water uptake owing to the absence of deep-rooted shrubs. Moisture profiles reversed after June to show lower water contents throughout the profile on the unburned section. Dense stands of sagebrush were destroyed from the fire allowing many more species to emerge thereby increasing species diversity. Seed sources contributing to this species diversification were from either the existing seedbank and/or wind-blown sources. Measurements are ongoing and the results are expected to help close a knowledge gap about barrier recovery after major disturbances.

Nonphotochemical hole burning of organic dyes and rare earth ions in polymers and glasses: a probe of the amorphous state  

SciTech Connect (OSTI)

New and in depth studies of amorphous materials (e.g., glasses and polymers) probed via the low temperature optical technique of nonphotochemical hole burning (NPHB) are presented. An extensive review of the phenomena itself, along with selected topics involving the use of persistent hole burning techniques, is given. In addition, a semi-complete tabulation of essentially all hole burning systems to date is included. The deuteration dependence in an amorphous host is examined for the system of tetracene in an ethanol/methanol mixture. The results illustrate the importance of hydrogen bonding in the hole burning process. The discovery of a highly efficient (or facile) class of hole burning systems, i.e., ionic dyes in hydroxylated polymers (i.e., poly(vinyl alcohol) (PVOH) and poly(acrylic acid) (PAA)), is presented and discussed. Ultrafast relaxation processes (i.e., dephasing) are studied for the system of cresyl violet perchlorate (CV) in PVOH. Further, for the first time, NPHB of rare earth ions, specifically Pr/sup +3/ and Nd/sup +3/, in a soft organic glass (i.e., PVOH) is discussed briefly. Detailed experimental results of two related phenomena, spontaneous hole filling (SPHF) and laser induced hole filling (LIHF), are presented and discussed for several systems: rhodamine 560 perchlorate (R560), rhodamine 640 perchlorate (R640), CV, Pr/sup +3/ and Nd..mu../sup 3/ in either PVOH or PAA. A theoretical model is developed for SPHF. The model invokes a correlated feedback mechanism from the anti-hole, which is able to account for the fact that no line broadening is observed. A tentative model is also presented for the phenomenon of LIHF.

View discovery in OLAP databases through statistical combinatorial optimization  

SciTech Connect (OSTI)

OnLine Analytical Processing (OLAP) is a relational database technology providing users with rapid access to summary, aggregated views of a single large database, and is widely recognized for knowledge representation and discovery in high-dimensional relational databases. OLAP technologies provide intuitive and graphical access to the massively complex set of possible summary views available in large relational (SQL) structured data repositories. The capability of OLAP database software systems to handle data complexity comes at a high price for analysts, presenting them a combinatorially vast space of views of a relational database. We respond to the need to deploy technologies sufficient to allow users to guide themselves to areas of local structure by casting the space of 'views' of an OLAP database as a combinatorial object of all projections and subsets, and 'view discovery' as an search process over that lattice. We equip the view lattice with statistical information theoretical measures sufficient to support a combinatorial optimization process. We outline 'hop-chaining' as a particular view discovery algorithm over this object, wherein users are guided across a permutation of the dimensions by searching for successive two-dimensional views, pushing seen dimensions into an increasingly large background filter in a 'spiraling' search process. We illustrate this work in the context of data cubes recording summary statistics for radiation portal monitors at US ports.

A feasibility study of reactor-based deep-burn concepts.  

SciTech Connect (OSTI)

A systematic assessment of the General Atomics (GA) proposed Deep-Burn concept based on the Modular Helium-Cooled Reactor design (DB-MHR) has been performed. Preliminary benchmarking of deterministic physics codes was done by comparing code results to those from MONTEBURNS (MCNP-ORIGEN) calculations. Detailed fuel cycle analyses were performed in order to provide an independent evaluation of the physics and transmutation performance of the one-pass and two-pass concepts. Key performance parameters such as transuranic consumption, reactor performance, and spent fuel characteristics were analyzed. This effort has been undertaken in close collaborations with the General Atomics design team and Brookhaven National Laboratory evaluation team. The study was performed primarily for a 600 MWt reference DB-MHR design having a power density of 4.7 MW/m{sup 3}. Based on parametric and sensitivity study, it was determined that the maximum burnup (TRU consumption) can be obtained using optimum values of 200 {micro}m and 20% for the fuel kernel diameter and fuel packing fraction, respectively. These values were retained for most of the one-pass and two-pass design calculations; variation to the packing fraction was necessary for the second stage of the two-pass concept. Using a four-batch fuel management scheme for the one-pass DB-MHR core, it was possible to obtain a TRU consumption of 58% and a cycle length of 286 EFPD. By increasing the core power to 800 MWt and the power density to 6.2 MW/m{sup 3}, it was possible to increase the TRU consumption to 60%, although the cycle length decreased by {approx}64 days. The higher TRU consumption (burnup) is due to the reduction of the in-core decay of fissile Pu-241 to Am-241 relative to fission, arising from the higher power density (specific power), which made the fuel more reactivity over time. It was also found that the TRU consumption can be improved by utilizing axial fuel shuffling or by operating with lower material temperatures (colder core). Results also showed that the transmutation performance of the one-pass deep-burn concept is sensitive to the initial TRU vector, primarily because longer cooling time reduces the fissile content (Pu-241 specifically.) With a cooling time of 5 years, the TRU consumption increases to 67%, while conversely, with 20-year cooling the TRU consumption is about 58%. For the two-pass DB-MHR (TRU recycling option), a fuel packing fraction of about 30% is required in the second pass (the recycled TRU). It was found that using a heterogeneous core (homogeneous fuel element) concept, the TRU consumption is dependent on the cooling interval before the 2nd pass, again due to Pu-241 decay during the time lag between the first pass fuel discharge and the second pass fuel charge. With a cooling interval of 7 years (5 and 2 years before and after reprocessing) a TRU consumption of 55% is obtained. With an assumed ''no cooling'' interval, the TRU consumption is 63%. By using a cylindrical core to reduce neutron leakage, TRU consumption of the case with 7-year cooling interval increases to 58%. For a two-pass concept using a heterogeneous fuel element (and homogeneous core) with first and second pass volume ratio of 2:1, the TRU consumption is 62.4%. Finally, the repository loading benefits arising from the deep-burn and Inert Matrix Fuel (IMF) concepts were estimated and compared, for the same initial TRU vector. The DB-MHR concept resulted in slightly higher TRU consumption and repository loading benefit compared to the IMF concept (58.1% versus 55.1% for TRU consumption and 2.0 versus 1.6 for estimated repository loading benefit).

Effect of H2/CO ratio and N2/CO2 dilution rate on laminar burning velocity of syngas investigated by direct measurement and simulation  

Science Journals Connector (OSTI)

Abstract Laminar burning velocities of syngas/air premixed flames, varying with H2/CO ratio (from 5/95 to 75/25) and N2 or CO2 dilution rate (from 0% to 60%), were accurately measured using a Teflon coated Heat Flux burner and OH-PLIF based Bunsen flame method. Experiments were carried out at atmospheric pressure and room temperature, with fuel/air equivalence ratios ranging from fuel-lean to fuel-rich. Coupled with experimental data, three chemical kinetic mechanisms, namely GRI-Mech 3.0, USC Mech II and Davis H2CO mechanism, were validated. The Davis H2CO and USC Mech II mechanisms appear to provide a better prediction for the laminar burning velocity. The laminar burning velocity variations with H2 and dilution gas contents were systematically investigated. For given dilution gas fraction, the laminar burning velocity reduction rate was enhanced as H2/CO ratio increasing. Effects of the syngas components and equivalence ratio variation on the concentrations of radical H and OH were also studied. It appears that there is a strong linear correlation between the laminar burning velocity and the maximum concentration of the H radical in the reaction zone for syngas. This characteristic is exclusively different from that in methane air premixed flame. These findings indicated that the high thermal diffusivity of the H radical played an important role in the laminar burning velocity enhancement and affected the laminar burning velocity reduction rate under dilution condition.

OXIDATION OF MERCURY ACROSS SCR CATALYSTS IN COAL-FIRED POWER PLANTS BURNING LOW RANK FUELS  

SciTech Connect (OSTI)

The objectives of this program were to measure the oxidation of mercury in flue gas across SCR catalyst in a coal-fired power plant burning low rank fuels using a slipstream reactor containing multiple commercial catalysts in parallel and to develop a greater understanding of mercury oxidation across SCR catalysts in the form of a simple model. The Electric Power Research Institute (EPRI) and Argillon GmbH provided co-funding for this program. REI used a multicatalyst slipstream reactor to determine oxidation of mercury across five commercial SCR catalysts at a power plant that burned a blend of 87% subbituminous coal and 13% bituminous coal. The chlorine content of the blend was 100 to 240 {micro}g/g on a dry basis. Mercury measurements were carried out when the catalysts were relatively new, corresponding to about 300 hours of operation and again after 2,200 hours of operation. NO{sub x}, O{sub 2} and gaseous mercury speciation at the inlet and at the outlet of each catalyst chamber were measured. In general, the catalysts all appeared capable of achieving about 90% NO{sub x} reduction at a space velocity of 3,000 hr{sup -1} when new, which is typical of full-scale installations; after 2,200 hours exposure to flue gas, some of the catalysts appeared to lose NO{sub x} activity. For the fresh commercial catalysts, oxidation of mercury was in the range of 25% to 65% at typical full-scale space velocities. A blank monolith showed no oxidation of mercury under any conditions. All catalysts showed higher mercury oxidation without ammonia, consistent with full-scale measurements. After exposure to flue gas for 2,200 hours, some of the catalysts showed reduced levels of mercury oxidation relative to the initial levels of oxidation. A model of Hg oxidation across SCRs was formulated based on full-scale data. The model took into account the effects of temperature, space velocity, catalyst type and HCl concentration in the flue gas.

Measurements of ultrafine particles from a gas-turbine burning biofuels  

SciTech Connect (OSTI)

Measurements of ultrafine particles have been performed at the exhaust of a low emission microturbine for power generation. This device has been fuelled with liquid fuels, including a commercial diesel oil, a mixture of the diesel oil with a biodiesel and kerosene, and tested under different loads. Primarily attention has been focused on the measurements of the size distribution functions of the particles emitted from the system by using particle differential mobility analysis. A bimodal size distribution function of the particle emitted has been found in all the examined conditions. Burning diesel oil, the first mode of the size distribution function of the combustion-formed particles is centered at around 2-3 nm, whereas the second mode is centered at about 20-30 nm. The increase of the turbine load and the addition of 50% of biodiesel has not caused changes in the shape of size distribution of the particles. A slightly decrease of the amount of particle formed has been found. By using kerosene the amount of emitted particles increases of more than one order of magnitude. Also the shape of the size distribution function changes with the first mode shifted towards larger particles of the order of 8-10 nm but with a lower emission of larger 20-30 nm particles. Overall, in this conditions, the mass concentration of particles is increased respect to the diesel oil operation. Particle sizes measured with the diesel oil have been compared with the results on a diesel engine operated in the same power conditions and with the same fuel. Measurements have showed that the mean sizes of the formed particles do not change in the two combustion systems. However, diesel engine emits a number concentration of particles more than two orders of magnitude higher in the same conditions of power and with the same fuel. By running the engine in more premixed-like conditions, the size distribution function of the particles approaches that measured by burning kerosene in the microturbine indicating that the distribution function of the sizes of the emitted particles can be strongly affected by combustion conditions.

Energetic Particle Physics In Fusion Research In Preparation For Burning Plasma Experiments  

SciTech Connect (OSTI)

The area of energetic particle (EP) physics of fusion research has been actively and extensively researched in recent decades. The progress achieved in advancing and understanding EP physics has been substantial since the last comprehensive review on this topic by W.W. Heidbrink and G.J. Sadler [1]. That review coincided with the start of deuterium-tritium (DT) experiments on Tokamak Fusion Test reactor (TFTR) and full scale fusion alphas physics studies. Fusion research in recent years has been influenced by EP physics in many ways including the limitations imposed by the "sea" of Alfven eigenmodes (AE) in particular by the toroidicityinduced AEs (TAE) modes and reversed shear Alfven (RSAE). In present paper we attempt a broad review of EP physics progress in tokamaks and spherical tori since the first DT experiments on TFTR and JET (Joint European Torus) including helical/stellarator devices. Introductory discussions on basic ingredients of EP physics, i.e. particle orbits in STs, fundamental diagnostic techniques of EPs and instabilities, wave particle resonances and others are given to help understanding the advanced topics of EP physics. At the end we cover important and interesting physics issues toward the burning plasma experiments such as ITER (International Thermonuclear Experimental Reactor).

In-Situ Safeguards Verification of Low Burn-up Pressurized Water Reactor Spent Fuel Assemblies  

SciTech Connect (OSTI)

A novel in-situ gross defect verification method for light water reactor spent fuel assemblies was developed and investigated by a Monte Carlo study. This particular method is particularly effective for old pressurized water reactor spent fuel assemblies that have natural uranium in their upper fuel zones. Currently there is no method or instrument that does verification of this type of spent fuel assemblies without moving the spent fuel assemblies from their storage positions. The proposed method uses a tiny neutron detector and a detector guiding system to collect neutron signals inside PWR spent fuel assemblies through guide tubes present in PWR assemblies. The data obtained in such a manner are used for gross defect verification of spent fuel assemblies. The method uses 'calibration curves' which show the expected neutron counts inside one of the guide tubes of spent fuel assemblies as a function of fuel burn-up. By examining the measured data in the 'calibration curves', the consistency of the operator's declaration is verified.

Ion kinetic effects on the ignition and burn of ICF targets  

E-Print Network [OSTI]

In this Article, we study the hydrodynamics and burn of the thermonuclear fuel in inertial confinement fusion pellets at the ion kinetic level. The analysis is based on a two-velocity-scale Vlasov-Fokker-Planck kinetic model that is specially tailored to treat fusion products (suprathermal {\\alpha}-particles) in a self-consistent manner with the thermal bulk. The model assumes spherical symmetry in configuration space and axial symmetry in velocity space around the mean flow velocity. Compared to fluid simulations where a multi-group diffusion scheme is applied to model {\\alpha} transport, the full ion-kinetic approach reveals significant non-local effects on the transport of energetic $\\alpha$-particles. This has a direct impact on hydrodynamic spatial profiles during combustion: the hot spot reactivity is reduced, while the inner dense fuel layers are preheated by the escaping {\\alpha}-suprathermal particles, which are transported farther out of the hot spot. We show how the kinetic transport enhancement of...

Molten salt destruction of energetic material wastes as an alternative to open burning  

SciTech Connect (OSTI)

The Lawrence Livermore National Laboratory in conjunction with the Energetic Materials Center ( a partnership of Lawrence Livermore and Sandia National Laboratories), is developing methods for the safe and environmentally sound destruction of explosives and propellants as a part of the Laboratory`s ancillary demilitarization mission. As a result of the end of the Cold War and the shift in emphasis to a smaller stockpile, many munitions, both conventional and nuclear, are scheduled for retirement and rapid dismantlement and demilitarization. Major components of these munitions are the explosives and propellants, or energetic materials. The Department of Energy has thousands of pounds of energetic materials which result from dismantlement operations at the Pantex Plant. The Department of Defense has several hundred million pounds of energetic materials in its demilitarization inventory, with millions more added each year. In addition, there are vast energetic materials demilitarization inventories world-wide, including those in the former Soviet Union and eastern Bloc countries. Although recycling and reusing is the preferred method of dealing with these surplus materials, there will always be the necessity of destroying intractable or unusable energetic materials. Traditionally, open bum/open detonation (OB/OD) has been the method of choice for the destruction of energetic materials. Public concerns and increasingly stringent environmental regulations have made open burning and open detonation of energetic materials increasingly costly and nearly unacceptable. Thus, the impetus to develop environmentally sound alternatives to dispose of energetic materials is great.

Molten salt destruction as an alternative to open burning of energetic material wastes  

SciTech Connect (OSTI)

LLNL has built a small-scale (about 1 kg/hr throughput unit to test the destruction of energetic materials using the Molten Salt Destruction (MSD) process. We have modified the unit described in the earlier references to inject energetic waste material continuously into the unit. In addition to the HMX, other explosives we have destroyed include RDX, PETN, ammonium picrate, TNT, nitroguanadine, and TATB. We have also destroyed a liquid gun propellant comprising hydroxyl ammonium nitrate, triethanolammonium nitrate and water. In addition to these pure components, we have destroyed a number of commonly used formulations, such as LX-10 (HMX/Viton), LX-16 (PETN/FPC461, LX-17 (TATB/Kel F), and PBX-9404 (HMX)/CEF/Nitro cellulose). Our experiments have demonstrated that energetic materials can be safely and effectively treated by MSD.We have also investigated the issue of steam explosions in molten salt units, both experimentally and theoretically, and concluded that steam explosions can be avoided under proper design and operating conditions. We are currently building a larger unit (nominal capacity 5 kg/hr,) to investigate the relationship between residence time, temperature, feed concentration and throughputs, avoidance of back-burn, a;nd determination of the products of combustion under different operating conditions.

Carbon Detonation and Shock-Triggered Helium Burning in Neutron Star Superbursts  

E-Print Network [OSTI]

The strong degeneracy of the 12C ignition layer on an accreting neutron star results in a hydrodynamic thermonuclear runaway, in which the nuclear heating time becomes shorter than the local dynamical time. We model the resulting combustion wave during these superbursts as an upward propagating detonation. We solve the reactive fluid flow and show that the detonation propagates through the deepest layers of fuel and drives a shock wave that steepens as it travels upward into lower density material. The shock is sufficiently strong upon reaching the freshly accreted H/He layer that it triggers unstable 4He burning if the superburst occurs during the latter half of the regular Type I bursting cycle; this is likely the origin of the bright Type I precursor bursts observed at the onset of superbursts. The cooling of the outermost shock-heated layers produces a bright, ~0.1s, flash that precedes the Type I burst by a few seconds; this may be the origin of the spike seen at the burst onset in 4U 1820-30 and 4U 1636-54, the only two bursts observed with RXTE at high time resolution. The dominant products of the 12C detonation are 28Si, 32S, and 36Ar. Gupta et al. showed that a crust composed of such intermediate mass elements has a larger heat flux than one composed of iron-peak elements and helps bring the superburst ignition depth into better agreement with values inferred from observations.

JV Task 126 - Mercury Control Technologies for Electric Utilities Burning Bituminous Coal  

SciTech Connect (OSTI)

The EERC developed an applied research consortium project to test cost-effective mercury (Hg) control technologies for utilities burning bituminous coals. The project goal was to test innovative Hg control technologies that have the potential to reduce Hg emissions from bituminous coal-fired power plants by {ge}90% at costs of one-half to three-quarters of current estimates for activated carbon injection (ACI). Hg control technology evaluations were performed using the EERC's combustion test facility (CTF). The CTF was fired on pulverized bituminous coals at 550,000 Btu/hr (580 MJ/hr). The CTF was configured with the following air pollution control devices (APCDs): selective catalytic reduction (SCR) unit, electrostatic precipitator (ESP), and wet flue gas desulfurization system (WFDS). The Hg control technologies investigated as part of this project included ACI (three Norit Americas, Inc., and eleven Envergex sorbents), elemental mercury (Hg{sup 0}) oxidation catalysts (i.e., the noble metals in Hitachi Zosen, Cormetech, and Hitachi SCR catalysts), sorbent enhancement additives (SEAs) (a proprietary EERC additive, trona, and limestone), and blending with a Powder River Basin (PRB) subbituminous coal. These Hg control technologies were evaluated separately, and many were also tested in combination.

Chapter 5 - Mineralogy of Burning-Coal Waste Piles in Collieries of the Czech Republic  

Science Journals Connector (OSTI)

Abstract Due to long-lasting tradition of coal mining and industrial history on the territory of Czech Republic, significant amount of waste piles of various ages and scales occur. Many of them, along with scarce occurrences of naturally burned coal measures, spontaneously ignited and subsequently, served as a source of diverse assemblage of newly formed minerals products of pyrometamorphism, alteration, and sublimation. Several new minerals associated with combustion metamorphism were first described from the Czech Republic: tschermigite (1853), rosickite (1931), letovicite (1932), kratochvlite (1937), kladnoite (1942), koktaite (1948), and rostite (1979). This chapter mainly focuses on two most famous localities, both situated to the Carboniferous sedimentary basins: Kladno Coal District in Central Bohemia near the capital Prague and Radvanice at Trutnov in Eastern Bohemia, close to border with Poland. These two localities, which were studied in detail, provided nearly 100 recently formed minerals and unnamed compounds.

Stable carbon fractionation in size-segregated aerosol particles produced by controlled biomass burning  

Science Journals Connector (OSTI)

Abstract Six different biomass fuel types (wood pellets, sunflower stalk pellets, straw pellets, buckwheat shells, mixed biomass waste pellets, and grain screenings) and wastewater sludge pellets were burned under controlled conditions to determine the effect of the biomass type on the emitted particulate matter mass and stable carbon isotope composition of bulk and size-segregated particles. Aerosol particles were sampled using the total suspended particle (TSP) sampler and a micro-orifice uniform deposit impactor (MOUDI). The results demonstrated that particle emissions were dominated by the submicron particles (size <1m) in all biomass types. However, significant differences in emissions of submicron particles and their dominant sizes were found between different biomass fuels. The isotopic fractionation between aerosol particles and original biomass material varied from ?0.940.23 to 1.120.16. The largest negative fractionation ?0.940.23 was obtained for the wood pellet fuel type while the largest positive isotopic fractionation (1.120.16) was observed during the grain screenings combustion. The carbon isotope composition of MOUDI samples compared very well with the isotope composition of TSP samples indicating consistency of the results. The measurements of the stable carbon isotope ratio in size-segregated aerosol particles suggested that combustion processes could strongly affect isotopic fractionation in aerosol particles of different sizes thereby potentially affecting an interpretation of ambient atmospheric observations.

Development of hot corrosion resistant coatings for gas turbines burning biomass and waste derived fuel gases  

Science Journals Connector (OSTI)

Carbon dioxide emission reductions are being sought worldwide to mitigate climate change. These need to proceed in parallel with optimisation of thermal efficiency in energy conversion systems on economic grounds to achieve overall sustainability. The use of renewable energy is one strategy being adopted to achieve these needs; with one route being the burning of biomass and waste derived fuels in the gas turbines of highly efficient, integrated gasification combined cycle (IGCC) electricity generating units. A major factor to be taken into account with gas turbines using such fuels, compared with natural gas, is the potentially higher rates of hot corrosion caused by molten trace species which can be deposited on hot gas path components. This paper describes the development of hot corrosion protective coatings for such applications. Diffusion coatings were the basis for coating development, which consisted of chemical vapour deposition (CVD) trials, using aluminising and single step silicon-aluminising processes to develop new coating structures on two nickel-based superalloys, one conventionally cast and one single crystal (IN738LC and CMSX-4). These coatings were characterised using SEM/EDX analysis and their performance evaluated in oxidation and hot corrosion screening tests. A variant of the single step silicon-aluminide coating was identified as having sufficient oxidation/hot corrosion resistance and microstructural stability to form the basis for future coating optimisation.

Meteorological measurements in the vicinity of a coal burning power plant  

SciTech Connect (OSTI)

High concentrations of sulfur dioxide (SO2) are commonly observed during the cool season in the vicinity of a 2.5 GW coal burning power plant located in the Mae Moh Valley of northern Thailand. The power plant is the source for nearly all of the observed SO2 since there are no other major industrial activities in this region. These high pollution fumigation events occur almost on a daily basis, usually lasting for several hours between late morning and early afternoon. One-hour average SO2 concentrations commonly exceed 1,000 micrograms/cu m. As a result, an increase in the number of respiratory type health complaints have been observed by local clinics during this time of the year. Meteorological data were acquired from a variety of observing platforms during an intensive field study from December 1993 to February 1994. The measurements included horizontal and vertical wind velocity, air temperature, relative humidity, and solar radiation. In addition, turbulent flux measurements were acquired by a sonic anemometer. SO2 measurements were made at seven monitoring sites scattered throughout the valley. These data were used to examine the atmospheric processes which are responsible for these high pollution fumigation events.

Performance assessment for the geological disposal of Deep Burn spent fuel using TTBX  

SciTech Connect (OSTI)

The behavior of Deep Burn Modular High Temperature Reactor Spent Fuel (DBSF) is investigated in the Yucca Mountain geological repository (YMR) with respect to the annual dose (Sv/yr) delivered to the Reasonably Maximally Exposed Individual (RMEI) from the transport of radionuclides released from the graphite waste matrix. Transport calculations are performed with a novel computer code, TTBX which is capable of modeling transport pathways that pass through heterogeneous geological formations. TTBX is a multi-region extension of the existing single region TTB transport code. Overall the peak annual dose received by the RMEI is seen to be four orders of magnitude lower than the regulatory threshold for exposure, even under pessimistic scenarios. A number of factors contribute to the favorable performance of DBSF. A reduction of one order of magnitude in the peak annual dose received by the RMEI is observed for every order of magnitude increase in the waste matrix lifetime, highlighting the importance of the waste matrix durability and suggesting graphite's utility as a potential waste matrix for the disposal of high-level waste. Furthermore, we see that by incorporating a higher fidelity far-field model the peak annual dose calculated to be received by the RMEI is reduced by two orders of magnitude. By accounting for the heterogeneities of the far field we have simultaneously removed unnecessary conservatisms and improved the fidelity of the transport model. (authors)

Feasibility Study of Supercritical Light Water Cooled Fast Reactors for Actinide Burning and Electric Power Production  

SciTech Connect (OSTI)

The use of supercritical temperature and pressure light water as the coolant in a direct-cycle nuclear reactor offers potential for considerable plant simplification and consequent capital and O&M cost reduction compared with current light water reactor (LWR) designs. Also, given the thermodynamic conditions of the coolant at the core outlet (i.e. temperature and pressure beyond the water critical point), very high thermal efficiencies of the power conversion cycle are possible (i.e. up to 46%). Because no change of phase occurs in the core, the need for steam separators and dryers as well as for BWR-type recirculation pumps is eliminated, which, for a given reactor power, results in a substantially shorter reactor vessel than the current BWRs. Furthermore, in a direct cycle the steam generators are not needed. If a tight fuel rod lattice is adopted, it is possible to significantly reduce the neutron moderation and attain fast neutron energy spectrum conditions. In this project a supercritical water reactor concept with a simple, blanket-free, pancake-shaped core will be developed. This type of core can make use of either fertile or fertile-free fuel and retain the hard spectrum to effectively burn plutonium and minor actinides from LWR spent fuel while efficiently generating electricity.

Dynamical and radiative response to the massive injection of aerosol from Kuwait oil burning fires  

SciTech Connect (OSTI)

The effects of the injection of large amount of soot comparable to that produced in the burning of oil wells in Kuwait were studied using a 2-D mesoscale model. During the three day numerical simulation the ground-atmosphere system appears to be strongly perturbed. A surface cooling is produced in the first two days above and downwind of the sources. The cooling, between -10 C over the desert and -0.5 C over the sea is dependent on the surface characteristics. The temperature decrease at the ground results in a stratified troposphere which inhibits convection and perturbs the normal diurnal variability of the boundary layer while the upper levels are driven by the radiative warming of the aerosol layer. In this region after few hours the simulation produces a warming of 0.8 C reaching a maximum of 6 C is after 60 hours. During the last 2 days of simulation the long wave radiation emitted by the low altitude atmospheric layers contribute to mitigate the surface cooling. A detailed discussion of the radiative and the dynamical interactions is given and it is shown that beside the specific interest in the short term effects these results may be useful to parameterize the smoke source for a General Circulation Model (GCM) simulation.

TEM Characterization of High Burn-up Microstructure of U-7Mo Alloy  

SciTech Connect (OSTI)

As an essential part of global nuclear non-proliferation effort, the RERTR program is developing low enriched U-Mo fuels (< 20% U-235) for use in research and test reactors that currently employ highly enriched uranium fuels. One type of fuel being developed is a dispersion fuel plate comprised of U-7Mo particles dispersed in Al alloy matrix. Recent TEM characterizations of the ATR irradiated U-7Mo dispersion fuel plates include the samples with a local fission densities of 4.5, 5.2, 5.6 and 6.3 E+21 fissions/cm3 and irradiation temperatures of 101-136?C. The development of the irradiated microstructure of the U-7Mo fuel particles consists of fission gas bubble superlattice, large gas bubbles, solid fission product precipitates and their association to the large gas bubbles, grain subdivision to tens or hundreds of nanometer size, collapse of bubble superlattice, and amorphisation. This presentation will describe the observed microstructures specifically focusing on the U-7Mo fuel particles. The impact of the observed microstructure on the fuel performance and the comparison of the relevant features with that of the high burn-up UO2 fuels will be discussed.

Method for detecting and correcting for isotope burn-in during long-term neutron dosimetry exposure  

DOE Patents [OSTI]

A method is described for detecting and correcting for isotope burn-in during-long term neutron dosimetry exposure. In one embodiment, duplicate pairs of solid state track recorder fissionable deposits are used, including a first, fissionable deposit of lower mass to quantify the number of fissions occuring during the exposure, and a second deposit of higher mass to quantify the number of atoms of for instance .sup.239 Pu by alpha counting. In a second embodiment, only one solid state track recorder fissionable deposit is used and the resulting higher track densities are counted with a scanning electron microscope. This method is also applicable to other burn-in interferences, e.g., .sup.233 U in .sup.232 Th or .sup.238 Pu in .sup.237 Np.

Two-dimensional simulations of thermonuclear burn in ignition-scale inertial confinement fusion targets under compressed axial magnetic fields  

SciTech Connect (OSTI)

We report for the first time on full 2-D radiation-hydrodynamic implosion simulations that explore the impact of highly compressed imposed magnetic fields on the ignition and burn of perturbed spherical implosions of ignition-scale cryogenic capsules. Using perturbations that highly convolute the cold fuel boundary of the hotspot and prevent ignition without applied fields, we impose initial axial seed fields of 20100 T (potentially attainable using present experimental methods) that compress to greater than 4 10{sup 4} T (400 MG) under implosion, thereby relaxing hotspot areal densities and pressures required for ignition and propagating burn by ?50%. The compressed field is high enough to suppress transverse electron heat conduction, and to allow alphas to couple energy into the hotspot even when highly deformed by large low-mode amplitudes. This might permit the recovery of ignition, or at least significant alpha particle heating, in submarginal capsules that would otherwise fail because of adverse hydrodynamic instabilities.

Effect of meteorological data averaging times on plume concentrations from explosive ordnance disposal open burning operations. Master`s thesis  

SciTech Connect (OSTI)

Explosive Ordnance Disposal (EOD) Open Burning (OB) operations are performed to treat and dispose of unserviceable munitions in the Department of Defense (DOD) inventory. This thesis effort sought to develop a computer model, based upon the Gaussian Puff Equation. The model varies from standard plume modeling practices by not making the assumption that the wind direction, wind speed and turbulence are uniform throughout the duration of the burn. The model assigns meteorological data to each explosion (puff) generated by the OB source. The experiments in this research effort assigned meteorological data to the puffs based upon averaging the weather data over 1, 10, and 60 minute periods. The results of the research showed that there was a statistically significant difference (95% confidence) between 1 minute and 60 minute weather data plume concentrations in the receptor grid in 100% of the experiments performed.

PHOTOCHEMICAL AND NON-PHOTOCHEMICAL HOLE BURNING IN DIMETHYL-S-TETRAZINE IN A POLYVINYL CARBAZOLE FILM  

SciTech Connect (OSTI)

Hole burning as well as fluorescence line narrowing experiments have been performed on the system dimethyl-s-tetrazine in polyvinyl carbazole films at low temperatures. The first singlet electronic absorption bands are typical (300 cm{sup -1} wide) of inhomogeneously broadened bands of guest molecules in amorphous organic hosts. Evidence is presented for both photochemical and non-photochemical hole burning. The narrowest holes observed were Lorentzian, had a width 0.44 cm{sup -1} at 1.8 K, and are believed to be of non-photochemical origin. A model which envisions the guest molecules to occupy different sites in the polymer host with a distribution of energy barriers between sites is used to describe these observations. The fast (20 psec) relaxation time implied by the 0,44 cm{sup -1} Lorentzian linewidth is interpreted as indicative of the rate of site interconversion in the excited state.

On the Effect of Explosive Thermonuclear Burning on the Accreted Envelopes of White Dwarfs in Cataclysmic Variables  

E-Print Network [OSTI]

The detection of heavy elements at suprasolar abundances in the atmospheres of some accreting white dwarfs in cataclysmic variables, coupled with the high temperatures needed to produce these elements requires explosive thermonuclear burning. The central temperatures of any formerly more massive secondary stars in CVs undergoing hydrostatic CNO burning are far too low to produce these elements. Evidence is presented that at least some cataclysmic variables contain donor secondaries that have been contaminated by repeated novae ejecta and are transferring this material back to the white dwarf. This scenario does not exclude the channel in which formerly more massive donor stars underwent CNO processing in ystems that underwent thermal timescale mass transfer. Implications for the progenitors of CVs are discussed.

Impact of agricultural waste burning in the Shandong Peninsula on carbonaceous aerosols in the Bohai Rim, China  

Science Journals Connector (OSTI)

Abstract A total of 115PM2.5 samples were collected for analyzing organic carbon (OC) and elemental carbon (EC) at Tuoji Island (TI), China from November 2011 to December 2012. The results showed that annual arithmetical means of OC and EC concentrations were 3.82.7 and 2.22.2?gm?3, which contributed 8% and 4% of PM2.5 mass concentrations, respectively. High EC concentrations occurred in winter, contributed mainly by EC outflow from the northwest source region, while high OC concentrations were found during spring, attributed largely to biofuel burning in the Shandong Peninsula, and short distance and favorable transport from the peninsula to the TI. Agricultural waste open burning in the peninsula caused the largest variability of OC concentration in summer. Eliminating agricultural field burning in the peninsula can reduce at least one-third of concentration levels and half of northward transport fluxes of OC and EC in Bohai Rim in summer.

Generation of long time series of burn area maps of the boreal forest from NOAAAVHRR composite data  

Science Journals Connector (OSTI)

A time series of burned land areas was generated for a 23year period (19842006) using 10-day composites of AVHRR data. The study area covers 1.6million km2 of boreal forest in western Canada. The algorithm was intended to be consistent throughout the study period and region, and to avoid commission errors, so as to obtain a reliable sample of temporal trends in burned area in the region. The algorithm relies on temporal comparisons of several spectral indices (GEMI, BAI), as well as near infrared reflectance. It emphasizes the stability of the post-fire signal, to avoid false detections associated with cloud, cloud shadows, missed data and radiometric or geometric calibration between AVHRR sensors. Final results show a very consistent temporal adjustment to official statistics and fire perimeters, with very low commission error (<10%), but medium to high omission error (50%). Burned areas in the region were predominantly associated with coniferous forest cover, with the Taiga and Boreal Shield ecozones, in latitudes between 56 and 60N, and predominantly at long distances from populated places.
