Useful heat value(UHV) pricing mechanism of coal deducted ash and moisture content from standard formula and in this coal is categorised into 7 grades.

Gross calorific value(GCV) of coal has 17 grades and prices are linked to the actual calorific value/quality of coal-by latika joshi

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.


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" | |}

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 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.
