The partitioning of arsenic during pulverized coal combustion | 2000 | arsenic partitioning; arsenic; pulverized coal combustion; coal-fired electric utility; coal; arsenic volatilization; volatilized arsenic. | An important issue facing the coal-fired electric utility industry is the environmental impact resulting from the release of arsenic contained in the coal. Depending on the forms of occurrence in the coal and transformation mechanism involved, arsenic-containing compounds may exit the furnace in the... |

Quantum mechanical study of molecular weight growth process by combination of aromatic molecules | 2001 | molecular weight growth; aromatic molecules; Quantum mechanics; Quantum mechanical study; aromatic moietes. | Formation pathways for high-molecular-mass compound growth are presented, showing why reactions between aromatic moieties are needed to explain recent experimental findings. These reactions are then analyzed by using quantum mechanical density functional methods. A sequence of chemical reactions bet... |

Reduction of nitric oxide on the char surface at pulverized combustion conditions | 2002 | reduction of nitric oxide; nitric oxide; pulverized combustion; char formation; char surface | This study presents an experimental evaluation of the rate of nitric oxide reduction on the char surface. It addresses the claim that the rate for the destruction of nitric oxide on the char surface has been underpredicted due to char deactivation in the process of char formation. Experiments conduc... |

Relationships between composition and pulmonary toxicity of prototype particles from coal combustion and pyrolysis | 2009 | toxicity; prototype particles; coal combustion; pyrolysis; health effects; coal combustion fly-ash particles | The hypothesis that health effects associated with coal combustion fly-ash particles are exacerbated by the simultaneous presence of iron and soot was tested through two sets of experiments. The first set created prototype particles from complete and partial combustion, or oxygen free pyrolysis of a... |

Size-range analysis of diesel soot with ultra-small angle X-ray scattering | 2005 | desiel soot; ultra-small angle X-ray scattering; Carbonaceous soot; diesel fuel; soot powders; soot | Carbonaceous soot produced in a small diesel engine test facility was investigated with ultra-small-angle X-ray scattering. Three soot samples produced using a reference diesel fuel and the reference fuel plus two oxygenate additives were investigated. The presence of objects at three typical size r... |

State space sensitivity to a prescribed probability density function shape in coal combustion system: Joint B-PDF versus clipped Gaussian PDF | 2000 | space sensitivity; coal combustion; b-PDF mixing model; three coal-off gas; pulverized-coal research furnace | The turbulent transport of three coal off-gas mixture fractions is coupled to a prescribed joint b-probability- density-function (b-PDF) mixing model. This physical transport and subgrid joint b-PDF mixing model is used to explore the incorporation of coal off-gas compositional disparities between t... |

Taking another look at Utah's tar sand resources | 2009 | tar sand; tar sand resources; unconventional energy resource; alternate energy resource; oil impregnated sandstone; oil sand; bitumous sandstone; energy resource | Recent increases in the price of crude oil have sparked renewed interest in unconventional energy resources, including Utah s tar sands. Tar sands (also called oil-impregnated sandstones, oil sands, and bituminous sandstones) are, as the names imply, sandstones that are saturated or filled with blac... |

Vaporization of arsenic, selenium and antimony during coal combustion | 2001 | coal-fired power; arsenic; selenium; antimony; coal combustion; ubmicron particles; vaporization during coal combustion | Accumulation of toxic trace elements generated by coal-fired power stations presents a serious threat to the environment. Field testing and laboratory studies have revealed the existence of trace elements in submicron particles emitted from power stations. Arsenic, selenium, and antimony are present... |

Virtual Radiometers for Parallel Architectures | 2012 | parallel architectures; virtual radiometers; a parallel ray tracing scheme; ray tracing algorithms; radiation; ray tracing; monte carlo; combustion; radiometer; parallel | Background: Parallelization of traditional ray tracing algorithms for radiation applications in participating media suffers from the large amount of inter-processor communication required to hand off rays between processors. As a result, strong scaling of these algorithms falls short of the required... |
