Abstract
Finite element method has been adopted to model the corona characteristics in duct-type electrostatic precipitators. The study involves the evaluation of the electric potential, electric field and the charge density in the interelectrode space. The calculated IN characteristics, electric field and potential distributions agreed well with those published before. Moreover, the I-V characteristics were measured for different values of wire-to-wire separation, wire diameter and wire-to-plate spacing for both single- and three-wire precipitators. The current density at the collecting plates was also measured and compared with those calculated by the proposed method. Fast convergence and simplicity characterize the proposed method.
