The electrostatic precipitator (ESP) has become a major dust removal device in industry, especially in coal-fired power plants, for over a hundred years. Although ESP is capable of removing most of the total PM mass, it may be less efficient in collecting micro-sized PM, a major source of air pollutant in many countries (Park and Chun 2002 ).

Dry ESPs Dry electrostatic precipitators are used to capture particles in dry product streams. They use periodic rapping to separate the accumulated dust from the collector plates and discharge electrodes. The dust layer (released by rapping) is collected in a hopper and then removed by an ash handling system.

How Electrostatic Precipitators Work - Basic The electrostatic precipitator functions by charging particulates within a gas stream as the gas flows through the ESP. These negatively charged particulates are attracted to positively charge large flat plates within the ESP, where they gradually accumulate upon the surfaces of the plates.
