Modeling of Back Corona in Pulse Energized “Multizone” Precipitators

Most of the electrostatic precipitators have at least two zones in which different supply parameters, rapping programs can be used. Lot of ESP models are handling the electrostatic precipitator as one block whit the same energization. However, separated operation of zones is useful to improve collection efficiency. In this paper authors represent an improved numerical ESP model that is capable to handle multiple zones with different properties. The represented modeling process is focused on different energization modes and the formation of back corona.
