How to calculate ncv from gcv of coal?
Net calorific value (NCV) can be calculated from gross calorific value (GCV) of coal using the formula: NCV = GCV - (0.09 * moisture content) for lignite and sub-bituminous coals, or NCV = GCV - (0.07 * moisture content) for bituminous and anthracite coals. The moisture content is usually provided on the coal analysis sheet.

NCV and GCV of coal?
net calorific value and gross calorific value GCV to NCV conversion: - Using the following IPCC formulae determine the NCV of those fortnightly samples - NCV = GCV - 0.212H - 0.0245M - 0.0008O - Where H - Percentage of Hydrogen, M - Percentage of Moisture and O - Percentage of Oxygen (as determined from the ultimate analysis report) - Please note that here GCV and NCV are in Mega Joule/kg, therefore it is required to do the necessary unit adjustments (1kcal/kg = (4.186/10^3) = 0.004186 MJ/kg) Assuming GCV = 18.4017MJ/kg, O =9.23%, H = 3.63%, M=7.45% (Source: Coal analysis report conducted independent testing laboratory - ' National Council for cement and building materials')
