crushing of coal in coke making process

  • Coke Making Process

    Coal is crushed and blended prior to being charged in a coke oven. A larry car charges the individual oven with the blended coal. In the coke oven, the coal is heated to 1,800°F for up to 18 hours. During that time, the volatiles of the coal are driven into the offgas and a pure carbon form called “coke12.2 Coke Production,12.2 Coke Production 12.2.1 General Metallurgical coke is produced by the destructive distillation of coal in coke ovens. Prepared coal is heated in an oxygen-free atmosphere (–coked–) until most volatile components in the coal are removed. The material remaining is a carbon mass called coke.

  • 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".What is Coke Clean Air Council,Coke is produced by heating coal at high temperatures, for long periods of time. This heating is called “thermal distillation” or “pyrolysis.” In order to produce coke that will be used in blast furnaces, coal is usually thermally distilled for 15 to 18 hours, but the process can take up to 36 hours.

    Jul 31, 2013· At the crushing station, the coals are crushed type by type with individual crusher settings. After the crushing process, the crushed coal is transported to the blending station. Each coal type is stored in a separate blending bin. Coal moisture control uses the waste heat from the coke oven gas to dry the coal used for coke making.Coal utilization Carbonization (coke making) Britannica,Coal utilization Coal utilization Carbonization (coke making): Coke is the solid carbonaceous residue that remains after certain types of coal are heated to a high temperature out of contact with air. The process of heating coal in this manner is referred to as carbonization or coke making. High-temperature carbonization, with which this section is concerned, is practiced to produce a coke
