Preparation Of Coal To Determine Calorific Value

Coal is generally analysed to determine its physical chemical thermal mechanical properties like size consist proximate values ultimate values calorific value and HGI. Calorific Value CV is an important thermal property of coal which indicates the amount of heat energy that could be liberated on combustion of a specific quantity.
