Coal Sampling & Testing | Power4you - "Power from Knowledge"

Dec 27, 2015· GCV is the Gross Calorific Value of the coal. It is denoted as Kcal per Kg.For example if the GCV of a coal is 4200 Kcal/Kg.That means if we are burning 1 kg of coal then the energy liberated is of 4200 Kcal (Kilo Calorie).So for measuring the GCV of the coal, a special equipment is used called Bomb Calorimeter.
