Gross Calorific Value
GCV, gross calorific value, is the quantity of heat produced by combustion. UHV, useful heat value, is the gradation of non-coking coal.
gross calorific value
Gross calorific value of coal
gcv(arb)=100-tm/100-im *gcv(adb)
NAR 5500 is equivalent how many GCV
yyyyyyyyyyyyyyy=GCV-(IM/9+5)*53
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
Theorotical value can be calculated using the results of ultimate analysis of coal . Based on the GCV of combustible value of coal.
net calorific value and gross calorific value 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) Assuming GCV = 18.4017MJ/kg, O =9.23%, H = 3.63%, M=7.45% (Source: Coal analysis report conducted independent testing laboratory - ' National Council for cement and building materials')
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)
to produce 1 ton of steam how many GCV of coal is required?
