Calorific Value, Coal Analysis, Kentucky Geological Survey

Oct 07, 2019· Calorific value is a measure of the amount of energy produced from a unit weight of coal when it is combusted in oxygen. A measured sample of coal is completely combusted in a bomb calorimeter, which is a device for measuring heat (ASTM method D5865-12; American Society for Testing and Materials, 2013, p. 648–666).

How to Calculate Calorific Value of Fuels? Combustion

Higher calorific value is the maximum heat energy liberated by the complete combustion of the fuel. This is also called as the gross calorific value of the fuel. If we subtract from the higher calorific value, an amount of heat required to evaporate the water formed, we get Lower Calorific Value (LCV) or Net Calorific Value (LCV) or Net
