Oct 07, 2019· Dry, mineral matter-free 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 D388-12; American Society for Testing and Materials, 2013, p. 390–396). For this basis, a calculation is needed to determine mineral-matter content rather than ash yield.
for estimating GCV on dry basis as follows; GCV = 0.3536(FC) + 0.1559(VM) – 0.0078(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-
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 Vis-NIR-SWIR (350–2500 nm) range.
Coal Quantity. Since coal has a heat value of 20,000 kJ/kg, for producing one kw.hr we require (10765 / 20000) 0.538 kg of coal. This translates to (0.538 x 100 x 1,000) 53800 kg/hr (53.8 T/hr) of coal for an output of 100 MW. Coal Cost. Basic cost of coal depends on the market conditions.

Based on a simple proportion calculation, multiplying by a factor [100-8]/ [100-20] the HHV will be 21620 kJ/kg. In real life, Coal analysis takes place in the laboratory. The coal is spread out and air-dried to remove most of the surface moisture. The Coal Analysis and Calorific Value is determined and reported as on Air Dried Basis (ADB).
