The gross calorific value (GCV) or heating value of a sample of fuel is one of the important property which defines the energy of the fuel. Many researchers have proposed empirical formulas for estimating GCV value of coal. There are some known methods like Bomb Calorimeter to determine the GCV .
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
