Bursey, J. AND D. P. Dayton. SOURCE SAMPLING FINE PARTICULATE MATTER: A KRAFT PROCESS HOGGED FUEL BOILER AT A PULP AND PAPER FACILITY, VOLUMES 1 AND 2. U.S. Environmental Protection Agency, Washington, DC, EPA/600/R-03/100, 2003.
Impact/Purpose:
Fine particulate matter of aerodynamic diameter 2.5 m or less (PM-2.5) has been found harmful to human health, and a National Ambient Air Quality Standard for PM-2.5 was promulgated by the U.S. Environmental Protection Agency in July 1997. A national network of ambient monitoring stations has been established to assist in determining areas which do not meet the ambient standard for PM-2.5. For such areas, it is important to determine the major sources of PM-2.5. The chemical mass balance source-receptor model is used in this process. Such a model requires knowledge of the PM-2.5 chemical composition emitted from each significant source. The report provides a chemical composition profile for the PM-2.5 emitted from an auxiliary boiler fired with a mixture of wood bark (hogged wood waste) and bituminous coal at a pulp and paper mill utilizing the Kraft process. The boiler was rated to generate a maximum of 889 MBtu/hour and was equipped with a control system which included a multicyclone-electroscrubber system installed on the flue gas duct and bag filters installed on the vents of the coal bins, scrubber ash silo, and boiler ash silo. Along with the PM-2.5 emission profile, data are also provided for gas-phase emissions of several organic compounds. Gaseous reduced sulfur compound emissions were not included in this study. Data are presented both as mass emission factors (mass of emitted species per unit mass of fuel consumed) and as mass fraction composition, (e.g., mass fraction of individual components comprising the PM-2.5).
