Web12 apr. 2024 · The industrial process and refining of coal reduces its volume and almost one-third of the volume of coal is obtained as coke. Coal produces a lot of soot and smoke on combustion. Since coke is devoid of all the gaseous impurities and contaminants, it is a cleaner fuel as compared to coal which produces a lot of soot on combustion. 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".
