101 Relationships between composition and pulmonary toxicity of prototype particles from coal combustion and pyrolysis2009toxicity; prototype particles; coal combustion; pyrolysis; health effects; coal combustion fly-ash particlesThe 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...
102 Experimental evaluation of the effects of quench rate and quartz surface area on homogeneous mercury oxidation2007quench rate; quartz surface area; homogeneous mercury oxidation; mercury chemistryThis paper presents a mercury oxidation data set suitable for validation of fundamental kinetic models of mercury chemistry and for mechanism development. Experimental facilities include a mercury reactor fitted with a 300-W, quartz-glass burner and a quartz reaction chamber. While operated with a t...
103 Quantum mechanical study of molecular weight growth process by combination of aromatic molecules2001molecular 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...
104 Size-range analysis of diesel soot with ultra-small angle X-ray scattering2005desiel soot; ultra-small angle X-ray scattering; Carbonaceous soot; diesel fuel; soot powders; sootCarbonaceous 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...
105 Fine particle emissions from residual fuel oil combustion: Characterization and mechanisms of formation2000fine particle emissions; residual fuel oil combustion; airborne fine particulate matter (PM); particulate characteristics of PMThe 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...
106 Reduction of nitric oxide on the char surface at pulverized combustion conditions2002reduction of nitric oxide; nitric oxide; pulverized combustion; char formation; char surfaceThis 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...
