Formulas for calculating the calorific value of coal and coal chars: Development, tests, and uses

Fuel Processing Technology, 1983
Abstract A new formula for calculating the calorific value of coal from its ultimate analysis has been obtained by regression analysis of a data bank consisting of data on 775 samples of U.S. coals of all ranks. It yielded zero average difference between observed and calculated values and a standard deviation of 129 Btu/lb (300 kJ/kg).
