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)

NAR 5500 is equivalent how many GCV
By Dulong formula
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.
The relation between GCV at AD (as received basis) and ADB (air dried basis) and ARB (as received basis) can be calculated using the formula: GCV(ADB) = GCV(AD) - [H2O * latent heat of vaporization] GCV(ARB) = GCV(ADB) / (1 - moisture content)
Weighted average of oil consumed:(rate of oil A * quantity of oil A) + (rate of oil B * quantity of oil B)Quantity of oil (A+B)GCV of oil consumed:(GCV * quantity of oil A) + (GCV * quantity of oil B)Quantity of oil (A+B)

I do not think that there can be a way to calculate GCV from the UHV. UHV is calculated by taking into account the percentage of two Proximate components of coal i.e. Ash and Moisture. But GCV is calculated using the percentage of ultimate components such as C, H, O, S. UHV(Kcal/Kg) = 8900-138(A+M) GCV is calculated using Dulong's Formula GCV(KJouls/kg) = 333xC + 1442(H -O/ 8) + 93 x S (GCV and all components in dry basis) {| style="width: 81pt; border-collapse: collapse" width="108" |- style="height: 28.5pt; mso-height-source: userset" | class="xl64" style="border: 0px black; width: 81pt; height: 28.5pt; background-color: transparent" width="108" height="38" | |}
What is nar
It is 2.2 or 2.20 which both have the same values as 2.200
to produce 1 ton of steam how many GCV of coal is required?
Coal If we know the ultimate analysis of fuel, we can easily calculate its GCV. The basic principle is that there are only 3 components in a fuel which generate heat. These are: Carbon, Hydrogen and Sulphur. According to Dulong's formula gross calorific value of a fuel is; GCV = ((35.5 x C + 114.8 x H + 9.5 x S - 14.5 x O) x 1000) / (100 x 4.1868) Each multiple of carbon, hydrogen and sulphur represents heat generated by its one mole. The formula gives GCV in kcal/kg. Simple isnt it !
