The calorific value defines the energetic content of the materials; it is the amount of heat a substance produces after complete combustion. You can express it as the gross calorific value (GCV) or high heating value. Also, the calorific value of a substance (generally, solid biofuel or food) is the specific energy of combustion for a unit mass.

For moisture, volatile matter, fixed carbon, and GCV, band depth at 1900, 2900, 2310, 3410, and 3280 nm were applied to correlate these properties. Results suggested that reflectance spectroscopy could be used for on-line monitoring of coal properties. Also, it reported that absorption band depth generally appears in the lowest …

(GCVARB) is different than the equilibrated GCV (GCVEM)determined at the loading point. Hence, the GCV of coal may be considered after allowing an adjustment for total moisture as per the formula given as under: GCVARB = [GCVEMX (100-TM)] I(100- EM) Where: GCVARB = Gross Calorific Value of coal after moisture correction (kcal/kg),

1.. IntroductionCalorific value is an important property, indicating the useful energy content of coal and, thereby, its value as fuel. Heating value is a rank parameter, but is also dependant on the maceral and mineral composition (Hower and Eble, 1996).A number of equations have been developed for the prediction of gross calorific value …

The GCV is a parameter that plays a major role in the design and safety of power plants. As a result, numerous researchers have created models to estimate the GCV based on simpler variables like proximate and ultimate compositions (van Aarde 2019). Some of these models were made for particular coal kinds from different geographical ...
