In the last few decades, electrostatic precipitators (ESP) have been improvement and many new methods have been implemented to increase in term of Particles collection efficiency in the sub micrometer size range. electrostatic precipitators rely on corona discharge processes to remove airborne dust particles. To understand particle behavior and flow dynamics inside electrostatic precipitators, a precise measurement of the electric field and charge density distribution is required. The electric field and charge density distributions in the negative wire-to-duct electrostatic precipitator were calculated using Poisson and charge conservation equations. typical efficiency of ESP as a function of geometrical and operation factors. In this paper, ESP designed and simulated using COMSOL Multiphysics® 5.5.The effects of the distance between discharge-wires on collection efficiency was studied.
