This paper discusses how to upgrade electrostatic precipitators (ESPs) with four 330 MW coal-fired generators. For the two four-field ESPs, the upgrading includes replacement of high-voltage electrodes and the high-voltage power sources. For the two five-field ESPs, only the power sources are retrofitted. The ESP outlet PM10 and PM2.5 emissions are less than 15 and 2 mg/m3, respectively. The flue gas desulfurization (FGD) can be effective for PM10 emission reduction, but not for PM2.5. This paper also presents the rapping and gas temperature effects on particle emission. When reducing the gas temperature from 150-160℃ to about 110℃, PM2.5 emission from the ESP or FGD is always less than 2 mg/m3.
