[[File:Elektrofilter Maria Gugging.jpg|thumb|Electrostatic precipitator]] [[File:PowerStation3.svg|thumb|Location of ESP in a power station (no. 25)]] An '''electrostatic precipitator''' ('''ESP''') is a [[Machine|device]] to [[Filter|capture]] [[particle]]s from a flowing [[gas]]. It uses the [[force]] produced by [[electrostatic]] [[Electric charge|charge]]. ESPs are used in many [[power plant]]s which burn [[fuel]] to produce [[energy]], such as in [[power station]]s.
