Extract from COAL Krevelen. (page 529) "All the empirical equations are modifications of the original Dulong equation with "some theoretical foundation", and are, by adaption to empirical CV data of coal, de facto empirical relationships. The correlations given by GIVEN (1986) and NEAVEL (1986) are the most reliable."
India is endowed with a vast reserve of coals but out of this approximately 87 per cent are high volatile noncaking coals which are mainly used in thermal power plant. These coals span from subbituminous to bituminous range and have wide range of ash content.
