The Tennessee Valley Authority (TVA) has conducted several field experiments to examine the chemical interactions in isolated coal-fired power plant plumes, Particularly the conversion of sulfur dioxide (SO/sub 2/) to sulfate (SO/sub 4//sup 2 -/) aerosols. Six field studies have been conducted at three TVA power plants - Cumberland, paradise, and Colbert Steam Plants - each of which has a different boiler configuration. Studies were conducted during all seasons of the year. Samples were usually collected between sunrise and noon; however, at Cumberland and Paradise Steam Plants, samples were also collected in the afternoon and after sunset. The effect of several meteorological parameters on the conversion rate was investigated from the results of these studies. During one study at Cumberland Steam Plant, samples were taken during periods of reduced and normal electrostatic precipitator (ESP) operation; results from this study were used to investigate the effect of particle loading in the plume on the conversion rate.
