It emphasizesunderstanding the corona dischargemechanism and itsrole in particlecharging and collection, whileanalyzing the influence of electrodegeometry, electricalpolarity, and airflowcharacteristics on separationefficiency. The studyalsoaims to determine the optimal operating configuration for improving the collection of fine particles, which are the mostharmful to humanhealth, therebyenhancing the purification of industrialgases and contributing to the protection of the environment and public health.frThesis
