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 difference between GCV and UHV?
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
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" | |}
How many GCV of coal is required to produce steam?

How do you calculate exact coal gcv?
By Dulong formula
What is the full form of gcv in coal?
gross calorific value
FOrmula to calculate gcv of coal?
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)
Determine the calorific value of fuel using dulong's formula?
Theorotical value can be calculated using the results of ultimate analysis of coal . Based on the GCV of combustible value of coal.
Gcv of the coal?
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 !
