Title: [An investigation of the formation of] polycyclic aromatic hydrocarbon (PAH) emissions when firing pulverized coal in a bench-scale drop tube reactor

Abstract

The Clean Air Act Amendments (CAAA) of 1990 contain provisions which will set standards for the allowable emissions of 188 analytes designated as hazardous air pollutants (HAPs). This list of HAPs was used to establish an initial list of source categories for which EPA would be required to establish technology-based emission standards, which would result in regulated sources sharply reducing routine emissions of toxic air pollutants. Polycyclic organic matter (POM) has also been referred to as polynuclear or polycyclic aromatic compounds (PACs). Nine major categories of POM have been defined by EPA. The study of organic compounds from coal combustion is complex and the results obtained so far are inconclusive with respect to emission factors. The most common organic compounds in the flue gas of coal-fired power plants are polycyclic aromatic hydrocarbons (PAHs). Furthermore, EPA has specified 16 PAH compounds as priority pollutants. These are naphthalene, acenaphthylene, acenaphthene, fluorene, phenanthrene, anthracene, fluoranthene, pyrene, chrysene, benz[a]anthracene, benzo[b]fluoranthene, benzo[k]fluoranthene, benzo[a]pyrene, indeno[1,2,3-cd]pyrene, benzo[ghi]perylene, and dibenz[ah]anthracene. Penn State`s Combustion Laboratory is equipped to collect and analyze the HAPs in the flue gas from fossil fuels combustion. The overall objective of this study was to examine the effect of unit temperature on PAH emissions. Amore » Modified Method 5 sampling train was used to isokinetically collect samples at desired locations in flue gas streams. The collected sample can be separated into solid, condensed liquid and gaseous phases. The PAHs of interest are extracted from the collected sample, concentrated, then separated and quantified by gas chromatography/mass spectrometry (GC/MS). This study was conducted using a bench-scale drop-tube reactor (DTR). The fuel selected for this study was a Middle Kittanning seam coal pulverized to 80% passing US Standard 200 mesh (commonly referred to as pulverized coal, or PC grind).« less
