01-05-2009· The coal samples were analyzed as per the Indian Standards,and GCV was determined by bomb calorimetric method . In the determination of GCV, the water vapour arising from moisture in coal as well as water vapour produced from the combustion of hydrogen condenses inside the bomb where its latent heat of vaporization is recovered.
Since 1961, the average gross calorific value of the domestic thermal coal supply has almost halved to 3300 kcal/kg. This decline will continue as the share of inferior Indian coal is expected to increase progressively. Consequently, coal consumption per unit power generation and hence ash amount and emissions are observed to be continuously rising.

Best Answer: GCV (gross calorific value) is the quantity of heat produced by combustion when the water produced by combustion is allowed to return to the liquid state. NCV (net calorific value) is the quantity of heat produced by combustion when the water produced by combustion remains gaseous.
Energy content or calorific value is the same as the heat of combustion, and can be calculated from thermodynamical values, or measured in a suitable apparatus:. A known amount of the fuel is burned at constant pressure and under standard conditions (0°C and 1 bar) and the heat released is captured in a known mass of water in a calorimeter. If the initial and final temperatures of the water

Indian coal is of mostly sub-bituminous rank, followed by bituminous and lignite (brown coal). The ash content in Indian coal ranges from 35% to 50%. Chemical composition of the coal is defined in terms of its proximate and ultimate (elemental) analysis.
Coal is one of the primary sources of energy, accounting for about 67% of the total energy consumption in the country. India has some of the largest reserves of coal in the world. Indian coal has high ash content and low calorific value. However, with the present rate of around 0.8
