Particulate matter emission is one of the major air pollution problems of processing industries. The fine parti- cles are considered potentially hazardous to health because of their high probability of deposition in deeper parts of the respiratory tract. Electrostatic precipitators are most common, effective and reliable particulate control devices, which handles large gas volumes with a wide range of inlet temperatures, pressures, dust volumes and acid gas conditions. Its performance is significantly affected by its complex flow distribution. Here the scope of the project is flow performance improvement of ESP for the existing model and improving settling efficien- cy of industrial ESP system using CFD. Generally in ESP, the collection efficiency is governed by the follow- ing reasons. High velocity regions, recirculation region, particulate reentertainment (due to swirling, mixing with already deposited particles). In this project, a novel approach is tried to avoid the above stated problems. This may be tried out, by introduction of porous plates in the ESP model. Also baffles and porous plates are used for the design modifications of the industrial ESP system. In the modern day design process CFD is found to be reliable as good as experimental studies. It provides a good way to increase the insight and foresight of any industrial problems. Here CFD is used as a tool to improve the performance of ESP.
