The heating value of coal is given in BTUs per pound or
The heating value of coal is given in BTUs per pound, or kilojoules per kilogram (10000 Btu/lb = 23200 kJ/kg). Coal can range from 3500 Btu/lb (culm or waste coal) to 15,000 Btu/lb for dry prime hard coal. Many auxiliary systems must still run and consume drivepower, regardless of the energy (BTU) content of the coal.
