Abstract This report describes the results of a sampling and chemical analysis study of emissions from two coal-fired steam plants equipped with electrostatic precipitators for particulate control. The program objective was to define both emission and enrichment of trace elements in the flue gas exiting electrostatic precipitators operated at different process temperatures. Fly ash collected from the stack using cyclones and cascade impactors was analyzed to define trace element concentration of individual size fractions. Trace element enrichment of ash fractions was compared with an enrichment model to define the dependence of enrichment on particle size. Samples of the feed coal at each station were subjected to density separation to determine the association of each element with mineral (ash) and organic (ash-free) phases of the coal. The 15 elements included in the coal and ash studies are: Arsenic, Beryllium, Cadmium, Calcium, Chromium, Copper, Fluorine, Lead, Manganese, Mercury, Nickel, Selenium, Titanium, Uranium, and Zinc.
