India is endowed with a vast reserve of coals but out of this approximately 87 per cent are high volatile non-caking coals which are mainly used in thermal power plant. These coals span from sub-bituminous to bituminous range and have wide range of ash content. While proximate analysis gives a preliminary insight of the coal, gross calorific value (GCV) is an important parameter which is being ...
The calorific value Q, of coal is the heat liberated by its complete combustion with oxygen. Q is a complex function of the elemental composition of the coal. Gross Calorific value Q is mostly determined by experimental measurements. A close estimate can be made with the Dulong formula:
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 function of gross calorific value and content of ballast in coal. The energy value of coal, or the fuel content, is
