Correlation of design parameters with performance

2018-5-1  The electrostatic precipitator (ESP) is a device that can efficiently remove fine suspended micron-size particles from a dry or wet air flow . The ESP utilizes corona discharge that is created by one or more wires (called the discharge electrode) to charge the suspended particles in the flow, distorts their trajectories with an induced electric field toward a collecting plate (called the collecting electrode), and
