This paper discusses the performance of a four-field electrostatic precipitator (ESP) used for a 75 t/h industrial coal-fired boiler. By using four traditional single-phase transformer-rectifiers (T/Rs), the PM10 and PM2.5 concentrations at the ESP outlet are around 120.4~219.7 and 9.6~22.3 mg·Nm-3, respectively. After retrofitting the four rectifiers with four ZH type three-phase T/Rs, the PM10 and PM2.5 concentration are about 6~17 and 1.8~3.3 mg·Nm-3, respectively. The PM2.5 to PM10 ratio ranges from 35% to 52%.
