Mechanism and kinetics of lead capture by kaolinite in a downflow combustor | 2000 | mechanism and kinetics; lead capture; kaolinite; downflow combustor; postflame reaction; lead vapor | An 18 kW, 6 m long, gas-fired downflow combustor was used to examine the postflame reaction between lead vapor and kaolinite. Since the focus of this work was to evaluate the reaction with lead vapor, samples were extracted at a temperature above the metal dew point. The sample was rapidly diluted w... |

On the relevance of surface growth in soot formation in premixed flames | 2000 | surface growth; soot formation; premixed flames; surface growth mechanisims; particle mass accumulation | The role of surface growth mechanisms in particle mass accumulation was investigated in rich, premixed, ethylene/air flames from non-sooting to moderately sooting conditions using in situ optical diagnostics and predictions from a detailed chemical kinetic model. Particles formed just after the flam... |

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... |

Urban planning tools for quality growth | 2000 | Formed in January of 1997, Envision Utah is a public/private community partnership dedicated to studying the effects of long-term growth in the Greater Wasatch Area of northern Utah. Sponsored by the Coalition for Utah's Future, Envision Utah and its partners - with extensive input from the public -... | |

Modeling the rich combustion of aliphatic hydrocarbons | 2000 | rich combustion; aliphatic hydrocarbons; kinetic mechanism; benzene formation; high-molecular-mass aromatic compounds | A new kinetic mechanism has been developed for the formation of benzene and high-molecular-mass aromatic compounds in rich flames of aliphatic hydrocarbons. The kinetic scheme emphasizes both the role of resonantly stabilized radicals in the growth of aromatics and the standard acetylene addition me... |

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... |

Modeling the vaporization of ash constituents in a coal-fired boiler | 2000 | vaporization of ash constituents; coal-fired boiler; minimizing harmful emissions; vaporization | Emissions of fine particulate and trace toxic metals are being subjected to increasing regulation. This paper addresses how the emission of these compounds can be influenced by changes in combustion conditions, particularly those selected to minimize NOx emissions. The vaporization and condensation ... |

Fine particle emissions from residual fuel oil combustion: Characterization and mechanisms of formation | 2000 | fine particle emissions; residual fuel oil combustion; airborne fine particulate matter (PM); particulate characteristics of PM | The characteristics of particulate matter (PM) emitted from residual fuel oil combustion in two types of combustion equipment were compared. A small commercial 732 kW rated fire-tube boiler yielded a weakly bimodal particulate size distribution (PSD) with over 99% of the mass contained in a broad co... |
