preparation of coal to determine calorific value

Calorific Value (ASTM D5865 ISO 1928 AS1038.5) The calorific value of coal or coke is the heat liberated when the solid fuel undergoes complete combustion in oxygen. In order to obtain accurate results SGS burns your fuel sample in a bomb calorimeter and measures the total heat energy.
