Abstract


Coal is the prime fuel for electricity generation in India and its utilization is continuously growing to meet the energy requirements of the country. The basic function of power plant is to convert energy in coal to electricity. Therefore, the first thing we should know is how much energy there is in coal. Energy content of coal is given in terms of kilojoules per kilogram (kJ/kg) of coal as the Gross calorific value (GCV) or High Heating Value (HHV) of coal. This value can be varies from 10500 kJ/kg to 25000 kJ/kg depending on the quality and type of coal. Indian coals are of poor quality and often contain 30-50% ash when shipped to power stations. In addition, over time the Calorific Value and the ash content of thermal coals have deteriorated as the better quality coal reserves are depleted and surface mining and mechanization expand. This poses significant challenges. Significant research has been done to determine the beneficial results of using high Calorific Value coals in thermal power plants.
