The influence of fly ash physical and chemical properties on electrostatic precipitation process

Flue gases emitted from coal fired power plants are mainly cleaned with electrostatic precipitators (ESP). Increased awareness of the effects of atmospheric pollution and tightening legislation force precipitator producers to increase their ESP efficiency, especially when collecting very fine particulates (PM2.5). The fly ash characteristic parameters are formatted during combustion process and its depend on the coal type as well as boiler parameters and combustion conditions. Due to that many series of tests were done to investigate the influence of fly ash physical and chemical properties on ESP operation.
