Abstract

The report gives results of a field performance test of an electrostatic precipitator (ESP) which uses SO3 as the conditioning agent. The ESP is at an electric utility power plant, burning approximately 1% sulfur coal. Tests were conducted with and without injection of the SO3. The ESP performance was characterized in terms of particle collection efficiency and the chemical composition of particulate and gaseous emissions. Fly ash resistivity and dust opacity were also measured. Results show an average increase in overall efficiency from 80% to 95% with injection of the SO3. This is accompanied by a decrease in fly ash resistivity, a decrease in opacity, and an increase in SO3 concentration entering and leaving the ESP. Approximately 80% of the injected SO3 escaped the ESP.
