Electrostatic Precipitators: Types, Operation

Electrostatic precipitators can achieve efficiency rates as high as 99% under optimal conditions. The removal efficiency ( eta ) of particles can be calculated using the Deutsch-Anderson equation: [ eta = 1 - e^{-frac{eAV}{Q}} ] where ( e ) is the elementary charge, ( A ) is the collected area, ( V ) is the voltage, and ( Q ) is the gas flow rate.

Design and Operation of Electrostatic Precipitators

Dust particles are removed from a gas stream in electrostatic precipitators due to the action of electrostatic forces. Between a positive and a negative electrode an electric field is established in which the charged dust particles are forced to move in the direction of the collecting electrode on the surface of which a very porous layer of dust builds up with time.
