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.

Difference in GCV and UHV of coal?

GCV (Gross Calorific Value) measures the total energy content in coal, while UHV (Useful Heat Value) considers only the heat value that can be practically utilized. UHV takes into account factors such as moisture and ash content that can impact the efficiency of energy conversion processes. Overall, UHV provides a more realistic indication of the usable energy in coal compared to GCV.


What is the relation between gcv at ad and adb and arb?

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)


How do you convert gross calorific value to net calorific value?

You can convert gross calorific value (GCV) to net calorific value (NCV) by subtracting the latent heat of vaporization of water formed during combustion from GCV. The equation for this is NCV = GCV - 2.5 x (9 x % H2 - % O2), where % H2 is the percentage of hydrogen in the fuel and % O2 is the percentage of oxygen in the fuel.


How do you calculate UHV to GCV in coal?

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" | |}
