A Review on Steam Coal Analysis Calorific Value. 2017814A Review on Steam Coal Analysis Calorific Value D Mahapatra INDIA I Introduction Coal includes chemical energy that is converted at a power plant into electric energy with determined efficiency The efficiency is dependent, among others, on coal quality parameters, since the efficiency of the boiler is a documentation and preparation
The natural fuel value of Indian coal is poor. On average, the Indian power plants using India's coal supply consume about 0.7 kg of coal to generate a kWh, whereas United States thermal power plants consume about 0.45 kg of coal per kWh. This is because of the difference in the quality of the coal, as measured by the Gross Calorific Value (GCV).
