1 kcal/kg 0.0041868 mj/kg. 1 metric ton (tonne) 1.10231 short tons. From GAR to NAR. The difference between net and gross as received (NAR v/s GAR) specific energy values is the latent heat of the water vapour which lowers the effective calorific value in the boiler. To convert from GAR to NAR for bituminous coals subtract approximately.
CV obtained by a calorimeter is the GCV. Calculation of CV of coal based on proximate analysis gives very rough estimate of the CV of the coal and is generally used for deciding the grade of coal and the usual formula adopted for this is 'useful heat value of coal in kcal/kg = 8900 – 138*(M + A)' where M is the percentage of moisture ...

Therefore, the first thing we should know is how much energy there is in coal. Energy content of coal is given in terms of KiloJoules (kJ) per Kilogram (kg) of coal as the Gross calorific value (GCV) or the Higher Heating value (HHV) of coal. This value can vary from 10500 kJ/kg to 25000 kJ/kg depending on the quality and type of the coal.
Calorific value GCV & HCV. 2. 2 CALORIFIC VALUE • It is defined as "the total amount of heat liberated,when a unit mass of fuel is burnt completely". • It is used to identified "the Efficiency of a Fuel ". •Wood has calorific value of 17 Kj/g. •The amount of heat can be measured by the following units : calorie, kilocalorie ...
