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. As a case study, application of the model is presented in case of such a situation, when aluminum-oxide dust must be separated from the gas-powder mixture. Determination of electrical and physical properties of the aluminum-oxide dust is involved in the paper as well as results of laboratory measurements predicting the performance of precipitation. Measurement results are compared with calculation results and the performance of the existing industrial electrostatic precipitator for different supply modes to select the best one among them.
