Calorific Value, Coal Analysis, Kentucky Geological Survey ...

 · 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).
