Abstract: Electrical energy is an essential ingredient for the industrial and all-round development of any country. This electrical energy is obtained by conversion from fossil fuels(coal, oil), nuclear and hydro sources. The availability of coal advances the promoters to install thermal power plants. Earlier, the power plant planners were concentrated more on generating power and hence not concentrated on pollution aspect and this continued up to late 70s. Later, the awareness has been created on pollution effect on the society and that makes the authorities to implement strict controlling norms to the power plant personnel to retrofit the present pollution control equipment. They have to change the older pollution control equipment like precipitators with the new ones or modify it by adding new components.
