Effect of wires number on corona discharge of an electrostatic precipitators

Abstract EN

This paper aims to analyze the behavoir of DC corona discharge in wires-to-planes electrostatic precipitators (ESPs) with effect of the wires number.

The current-voltage characteristics, onset corona voltage, electric onset field, breakdown voltage, current density and the apparent mobility of the charge carriers are analyzed.

The values of the current at the plane surface were the maximum beneath the wires which decreased when moving away from them.

Experimental results show that discharge current is strongly affected by the wires number, general formula was developed by Meng can be apply in wires-to-planes system of an electrostatic precipitators.

The Coopeman's model is reliable to determine the mobility of the charge carriers in this system.
