Abstract: Through data analysis on representative electrostatic Precipitators (ESPs) for ultra-low emission coal-fired power plants including the energy consumption, outlet particulate concentration, air leak percentage, pressure ｄｒｏｐ, it was shown that the energy consumption of 1000MW ESPs per unit generating capacity was 0.18% and which was less than the 0.22% of 600MW ESPs and the 0.3% of 300MW ESPs; the outlet particulate concentrations of 1000MW ESPs most were less than 15mg/m3 and there were many less than 10mg/m3. Then, it showed that the steel weight of 1000MW ESPs was 6% less than 600MW ESPs and 14% less than 300MW ESPs.
