The moisture in Coal consists of two parts. One is the moisture held within the molecular structure of the coal called “inherent moisture.” Removal takes place only at temperatures greater than 100 deg C. The second part is the moisture that is on the surface of the coal. This is normally due to the conditions and locations of the mines.
