This paper discusses electrostatic precipitator (ESP) sizing，refitting and upgrading with 2×600 MW coal-fired boilers. Each boiler is equipped with two five-fields ESPs and 40 high-voltage (HV) power sources. Upgrading the HV power source refers to replacing the 80 single-phase HV sources by using 80 three-phase HV sources. Refitting ESP mainly includes changing both HV and collection electrodes and their rapping systems of the first and second electrical fields. PM10 and PM2.5 emission concentrations at ESP outlets drop below 15 mg·Nm-3 and 1.0 mg·Nm-3, respectively. The PM2.5 to PM10 ratio is around 6.5%~7.5%. In comparison with previous emission, PM2.5 concentration drops down by more than 95%.
