Chapter 7 COAL - Pennsylvania State University

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 constituent of coals because it reduces the heating value (water does not burn!) and its weight adds ...
