Gcv of the coal

Answer 1

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 !
