Environmental Emission from Coal-Fired Power Plant and Control Technology

Coal combustion in power plants is one of the major sources of emission of pollutants like carbon dioxide (CO2), sulphur oxides (SOx), nitrogen oxides (NOx) and potentially toxic trace elements (Hg, As, Cd etc.) in atmosphere which have several impact on environment and human health. Coal being the major energy source of India, it is important to understand the air pollution and its impact on environmental and human health. Herein, various air pollutants emitted from power plants, its sources and their impact on environment and human health are briefly described. Best available technologies (BAT) and best environmental practices (BEP) to manage different pollutants were also discussed.
