How is coke obtained from coal
Web22 jul. 2024 · 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. Does coke burn hotter than coal? WebThe 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".
