The gas velocity characteristics within an electrostatic precipitator ESP play an important role in overall ESP performance. If local gas velocities are too high, then the aerodynamic forces upon the particles can overwhelm the electrostatic forces generated by the collecting surfaces and electrodes.
The electrical precipitator is a dry dust or liquid mist removal unit which utilizes the ionization of the process gas usually air to impart electrical charges on the suspended entrained particles and effect particle collection by attraction to an oppositely charged plate or pipe. This type of unit is in use in services which are difficult for other types of entrainment removal equipment.

This arrangement generates higher voltages in the first sections of the precipitator, where there is more particulate to be removed. Lower voltages will result in the final, cleaner precipitator sections when the same electrode
Electrostatic precipitator, also called electrostatic air cleaner, a device that uses an electric charge to remove certain impuritieseither solid particles or liquid dropletsfrom air or other gases in smokestacks and other flues.
