The higher calorific value or Gross calorific value (GCV) which supposes that the water of combustion is entirely condensed. The heat contained in this water is recovered. Il existe, pour la plupart des combustibles un rapport " GVC / NVC" entre ces deux coefficients : Natural gas: 1.111
In short, a coal having GCV 7200 KCal/Kg and GCV 7600 KCal/Kg MAY be both similar. The difference might be only that the former has been quoted on ARB basis and the later on ADB basis. ARB puts all variables into consideration and uses the total weight as the basis of measurement.

Aug 17, 2015· Sulphur % has to be assumed based on some previous analysis. Convert all the above to Air Dried Basis or As Received Basis, as per the Ash % and Moisture % in the proximate sample. Then Subtract from 100 to get Oxygen %. ADB to GAR GCV (ARB) = GCV (ADB) X (100-TM)/(100-IM) e.g. ADB 6300 x (100-18)/(100-12) = 5870 GAR
Yet upon asking the Basis, the traders seems confused. As a result, more often than not a few traders sell coal by claiming it to be of higher GCV when infact the difference between the 2 sample is simply the way the information has been presented. In short, a coal having GCV 7200 KCal/Kg and GCV 7600 KCal/Kg MAY be both similar.
Coal Specifications We exclusively trade thermal coal of Indonesian origin and offer three main calorific values – GAR 4200 kcal/kg, NAR 4700 kcal/kg and NAR 5500 kcal/kg. The table below indicates the typical specifications of each category of coal under the American Society for …
Moisture in coal varies from the point where it is received to the point where it enters the boiler. The variation in the moisture affects the reported heating value and analysis. The laboratory analysis is required to be corrected to the actual moisture content in the field. Methods for applying these corrections are explained here.

Volatile matter - Volatile matter is the material that is driven off when coal is heated to 950 °C in the absence of air under specified conditions. It consists of a mixture of gases, low-boiling-point organic compounds that condense into oils upon cooling, and tars. In general, coals with high volatile-matter content ignite easily and are highly reactive in combustion applications.
The gradation of non-coking coal is based on Gross Calorific Value (GCV), the gradation of coking coal is based on ash content and for semi coking /weakly coking coal it is based on ash plus moisture content, as in vogue as per notification.
