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 ...

The blended coal mass is heated for 12 to 20 hours for metallurgical coke. Thermal energy from the walls of the coke chamber heats the coal mass by conduction from the sides to the middle of the coke chamber. During the coking process, the charge is in direct contact with the heated wall surfaces and develops into an aggregate plastic zone .
