Electrostatic Precipitator are the devices which removes the entrained particulate contaminants and unwanted fine particles from the exhaust gases. The use of ESP, in particular power generation plant will help to reduce the environmental problems in two ways- On one hand, reducing the heavy or large particles, dust, fume or mist in exhaust gas and on the other hand it helps in cement industries for manufacturing the portland cement and bricks. It mainly works on the principle of electrostatic attraction (like charges repel; unlike charges attract). The contribution of this work lies in the comparative study and assessment of different factors that affects the performance of dry Electrostatic Precipitator in a developing country India to reduce the pollution particles.
