Volume X density of coal/2000 L X W X H X 85/2000
To calculate the fixed carbon, the moisture, ash and volatile matter contents (express the weights in percent) are added together and this sum is subtracted from 100 percent. Fixed Carbon = 100% - % (moisture) -% (ash) - % (volatile matter)
You can calculate a speed by dividing a distance by the time it takes to cover that distance. If you want the instantaneous speed (for situations of variable speed), you need to calculate the distance and time for a fairly short time interval (ideally, the limit, when the time approaches zero).
You can approximate a square root as a decimal or fraction. If you want the exact number, you have to leave it with the square root sign.
yyyyyyyyyyyyyyy=GCV-(IM/9+5)*53
to produce 1 ton of steam how many GCV of coal is required?
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)
Gross calorific value 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.
gross calorific value
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" | |}
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 !
(uhv + 3645 -75.4 m)/1.466
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.
