Determining the Gross Calorific Value in Coal. 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.

A coal testing procedure undergoes mainly two types of testing- Proximate Analysis and Ultimate Testing. The 'proximate analysis' includes the testing of Moisture, Ash, Volatile Matter, Fixed Carbon. The fixed carbon plays an important part in the burning of coal, whereas volatile matter plays a significant part in the ignition of fuel.

The Moisture in the Coal is both these put together and is the "Total Moisture.". A coal sampled at the mines having a moisture of 20%, after storage for a few weeks, when entering the boiler can have moisture of only 8%. If the Coal sampled at the mines has an HHV of 18800 kJ/kg the same coal at the boiler will have a higher HHV.
