Difference in GCV and UHV of coal?
GCV, gross calorific value, is the quantity of heat produced by combustion. UHV, useful heat value, is the gradation of non-coking coal.
What is the gcv of 2700 uhv coal?
(uhv + 3645 -75.4 m)/1.466
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" | |}
