12.2 Coke Production

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.

Groups

Group IIIA dusts are considered to be lower risk and Group IIIB is by far the largest group, it contains almost all carbon based dusts e.g. foodstuffs which are explosive. Group IIIC is considered high risk as static can be concentrated within the dust cloud and shorting of exposed electrical connections is a real hazard. As with Gas groups an increasing level of protection is required going
