A calorific value is a conversion factor used to convert a fuel quantity between natural units (mass or volume) and energy units (energy content). There are Net Calorific Values (NCV) and Gross Calorific Values (GCV).
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.
The heating value (or energy value or calorific value) of a substance, usually a fuel or food (see food energy), is the amount of heat released during the combustion of a specified amount of it. The calorific value is the total energy released as heat when a substance undergoes complete combustion with oxygen under standard conditions.
The gross calorific value of coal is most often used when calculating the total calorific value for a quantity of coal for fuel value purposes.
The lower heating value (LHV) is defined as the net calorific value and is determined by subtracting the heat of vaporization of water vapor (generated during combustion of fuel) fromthe higher heating value (Meriçboyu et al., 1998).

Coal, as it is commonly known, is a solid fossil hydrocarbon fuel material. The gross calorific value of coal is frequently used when determining the total calorific value for a specific amount of coal for fuel value purposes or when establishing the rank of classification of the coal material.
3.11.4 Calorific values of solid, liquid and gaseous fuels By custom the basic calorific value for solid and liquid fuels is the gross calorific value at constant volume and for gaseous fuels it is the gross calorific value at constant pressure.

Mtce million tonnes of coal ... Fixed Carbon (FC)– also Sulphur (S)and Calorific Value (CV)– can be expressed on any of the above bases. Coal Conversion Facts .
Gross calorific value of any coal, depends up on its maturity. Coking coal as such being more matured will have higher GCV. However, GCV reduces due to presence of ash forming mineral matters. Non Coking coals, though contains lower GCV, burns more efficiently in furnaces, than matured coking coals.
Let us look at calorific value of some well known fuels. Lignite has a calorific value of 5000 kcal per kg. Bituminous coal has a calorific value of 7600 kcal per kg. Anthracite coal has a calorific value of 8500 kcal per kg. Heavy oil has a calorific value of 11,000 kcal per kg. Diesel oil has a calorific value of 11,000 kcal per kg.

51 行· Lower Calorific Value (= Net Calorific Value - NCV = Lower Heating Value - LHV) - the products of combustion contains the water vapor and the heat in the water vapor is not recovered The table below gives the gross and net heating value of fossil fuels as well as some alternative biobased fuels.
The calorific value Q of coal [kJ/kg] is the heat liberated by its complete combustion with oxygen. Q is a complex function of the elemental composition of the coal. Q can be determined experimentally using calorimeters.
The Calorific Value varies on the geographical age, formation, ranking and location of the coal mines. It is expressed as kJ/kg in the SI unit system. Power plant coals have a Calorific Value in the range of 9500 kJ/kg to 27000 kJ/ kg.

CALORIFIC VALUE The heating value or calorific value of a substance, usually a fuel or food, is the amount of heat released during the combustion of a specified amount of it. The calorific value is a characteristic for each substance. It is measured in units of energy per unit of the substance, usually mass, such as: kcal/kg, kJ/kg, J/mol, Btu/m³.
4.7.4 Calorific value. Heating value of coal can be determined either of the two specified methods – ASTM D3286 or D2015.
