In this study, the gross calorific value (GCV) of coal was accurately and rapidly determined using eight artificial intelligence models based on big data of 2583 observations of coal samples in the Mong Duong underground coal mine (Vietnam). Accordingly, the volatile matter, moisture, and ash were considered as the key variables …
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 …
Gross calorific value (GCV) is one the most important coal combustion parameters for power plants. Modeling of GCV based on coal properties could be a key …

Thermal coal is quoted on a GAR basis, except for Europe/ARA, Richards Bay 6,000 kcal/kg, and Japan and Korea West CIF, which are quoted on a NAR (Net As Received) basis. Fixed carbon - Fixed carbon is the solid combustible residue that remains in the furnace after volatile matter is distilled off, comprised mostly of carbon but also …
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 1.09 mj/kg 260 kcal/kg 470 btu/lb
