COAL FIRED BOILER -PRINCIPALS

Main emissions from coal fired and lignite based thermal power plants are CO2, NOx, SOx, and air-borne inorganic particles such as fly ash, carbonaceous material (soot), suspended particulate matter (SPM), and other trace gas species. Thermal power plants, using about 70% of total coal in India4 (Garg et. al., 2002), are among the Large Point Sources (LPS) having significant contribution (47% each for CO2 and SO2) in the total LPS emissions …
