Received: • Accepted/Published Online: • Final Version: Abstract: Gross calorific value (GCV) of coal was predicted by using asreceived basis proximate analysis data. Two main objectives of the study were to develop prediction models for GCV .
1. As received basis: Coal in the condition as received by the consumer or the laboratory analyzing the coal. (This kind of coal includes all contents: Organic constituent, inorganic constituent (Inherent moisture, free moisture). Use the coal as received basis to represent coal content) 2. Air dried basis: The coal has naturally dried in the open air until it cannot dry or dissipate any more ...
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 containing ...
Oct 07, 2019· Dry, mineral matterfree basis: Data or results are calculated to a theoretical base as if there were no moisture or mineral matter in the coal sample (ASTM method D38812; American Society for Testing and Materials, 2013, p. 390–396). For this basis, a calculation is needed to determine mineralmatter content rather than ash yield.
for estimating GCV on dry basis as follows; GCV = (FC) + (VM) – (ash) where FC, VM and ash were in weight percent on dry basis and the unit of GCV was on mJ/kg. The correlation termed as ''general'' since it had been derived based on a large number of data points having widely varying proximate composi

ISO reproducibility values for C(db) % and GCV(db) 300J/g, converted to asreceived basis, are used in the calculation of Uncertainty. Fuel Ratio = Fixed Carbon / Volatile Matter Ballast = Ash(ar) + Total Moisture; Hydrogen in Coal: Refer to ASTM 3180 / ISO 1170
GCV of coal in Kcal/Kg = (355 x C + 1148 x H + 95 x S – 145 X O) / C, H, S, O are % figures obtained in the ultimate analysis of coal. Caloric value obtained by calorimeter is the only correct value and gives GCV

Coal Quantity. Since coal has a heat value of 20,000 kJ/kg, for producing one we require (10765 / 20000) kg of coal. This translates to ( x 100 x 1,000) 53800 kg/hr ( T/hr) of coal for an output of 100 MW. Coal Cost. Basic cost of coal depends on the market conditions.
In the present work, attempts have been made to estimate some important quality parameters (viz. ash, moisture, volatile matter, fixed carbon content, and GCV) of Indian coal which is known for its high ash content using diffuse reflectance spectroscopy in VisNIRSWIR (350–2500 nm) range.
