Most coals, as they are dug from the ground, have some amount of moisture associated with them. Gentle heating of coal at a temperature slightly above the boiling point of water causes a loss of weight from the sample that is defined as moisture. The moisture content of coals ranges from about 5% to almost 70%. Moisture is an undesirable ...
