How to Calculate the Coal Quantity Used in a Power Plant

Therefore the first thing we should know is how much energy there is in coal. Energy content of coal is given in terms of KiloJoules (kJ) per Kilogram (kg) of coal as the Gross calorific value (GCV) or the Higher Heating value (HHV) of coal. This value can vary from 10500 kJ/kg to 25000 kJ/kg depending on the quality and type of the coal.

FuelsHigher and Lower Calorific Values

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

Gross Calorific Valuean overview ScienceDirect Topics

Solid biomass fuels are more costly than coal oil and natural gas even when compared on a simple gross calorific value (GCV) or net calorific value (NCV) basis. The cost disadvantage of solid biofuels is accentuated by the lower comparative efficiency of use in power generation in synthesis gas production and in direct heating systems.
