This paper discusses electrostatic precipitation for fine particle emission control. According to the so-called electrostatic precipitator (ESP) index, a novel ESP sizing method is presented for both mechanical and electrical specifications. By using threephase rectifier transformer power sources, ESPs give very high collection for fine particle emission control. The ratio of PM2.5 over PM10 is between 6% and 20%. When PM10 emission is around 5-15 mg/m3, PM2.5 is below 2.5 mg/m3. By upgrading ESP and flue gas desulfurization (FGD), particle emissions can be reduced to below 5 mg/m3, and PM2.5 below 2.5 mg/m3.
