A sample of coal has following composition by mass C = 70 %, O = 8 %, H = 10 %, N = 3 %, S = 2%, Ash = 7 %. Calculate H.C.V. and L.C.V. using Dulong formula[Difficulty level-high]
The gross calorific value (GCV) or heating value of a sample of fuel is one of the important properties which defines the energy of the fuel. Many researchers have proposed empirical formulas for estimating GCV value of coal. There are some known methods like Bomb Calorimeter for determining the GCV in the laboratory. But these methods are cumbersome, costly and time consuming. In this paper ...
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 ...

Mar 06, 2015· Coal, as it is commonly known, is a solid fossil hydrocarbon fuel material. The gross calorific value of coal is frequently used when determining the total calorific value for a specific amount of coal for fuel value purposes or when establishing the rank of classification of the coal material.

Semi Coking Coal : based on (Ash+Moisture) percentage "Useful Heat Value" or "UHV" means the heat value determined on Equilibrated Basis by the following formula: UHV = 8900-138 x [A + M] where UHV = Useful Heat Value in kilo calories per
Jan 21, 2013· Coal India Ltd, a Maharatna company, is set to usher in a new era of pricing by benchmarking coal on the basis of its gross calorific value (GCV) from the 2012 calendar year. However, the transition to GCV pricing would be in phases, to assist sectors having huge discounts now.
Ultimate analysis gives fairly correct calorific value of coal and formula to be used is as below GCV of coal in Kcal/Kg = (355 x C + 1148 x H + 95 x S – 145 X O) / 4.1868 C, H, S, O are % figures obtained in the ultimate analysis of coal.
This is because diluting GCV would allow uncrushed coal, including boulders, and other impurities to be supplied," the official said. The GCV system divides available coal into 17 grades, against seven in the UHV system, thereby forcing coal companies to maintain precise levels of quality in a given sample.
