How Is Coal Inherent Moisture Related To Coal Total Moisture

Inherent Moisture or Bed Moisture is the moisture remaining in coal after natural drying in air. The Inherent Moisture is held within the molecular structure of the coal which can be removed only at temperatures greater than 100 deg C. The other moisture in the coal is on the surface of the coal

Surface moisture is like the drops of rain on a windshield inherent moisture is like that in green wood or held inside a sponge. As the coal rank increases the coal becomes more oil like so moisture is actually repelled by the internal structure of anthracite.
