Deutsch-Anderson Electrostatic Precipitator Theory
Electrostatic precipitators (ESPs) charge suspended solid dust particles via high-voltage DC corona discharge ($40 ext{ kV} - 80 ext{ kV}$). Charged particles migrate across the gas streamlines toward grounded collecting plates under an electrostatic drift velocity ($w_e$).
Classical Deutsch-Anderson Equation
η = 1 - e^[ - (A · w_e) / Q ] = 1 - e^[ - SCA · w_e ]
Where $A$ is total collecting plate area, $Q$ is volumetric gas flow, and $w_e$ is effective migration velocity.
