Oxidation of SO sub(2) on the surface of fly ash particles under low relative humidity conditions

Submicron fly ash particles can accumulate sulfate by surface oxidation of SO sub(2) in amounts between 9% and 45% of their mass at residence times between 0.3 and 12.5 hours at low humidities in the plume of a coal-fired power plant. The accumulation is size dependent and rapid decrease in the amou...

Zusammenfassung:Submicron fly ash particles can accumulate sulfate by surface oxidation of SO sub(2) in amounts between 9% and 45% of their mass at residence times between 0.3 and 12.5 hours at low humidities in the plume of a coal-fired power plant. The accumulation is size dependent and rapid decrease in the amount of fly ash due to fallout and dispersion prevents efficient removal of sulfur from the atmosphere by this mechanism.
