The Types of Coal: Composition, Usage and Energy Value

The coal ranking is based on levels of geological metamorphosis, fixed carbon, and calorific value. It is known as ASTM D388 –05 Standard Classification of Coals by Rank. As a general rule, the harder the coal, the higher its energy value and rank.

Calorific Value The Coal Resource - calimeroretie.be

The heating value (or energy value or calorific value) of a substance, usually a fuel or food (see food energy), is the amount of heat released during the combustion of a specified amount of it. The calorific value is the total energy released as heat when a substance undergoes complete combustion with oxygen under standard conditions.
