The Effect of Bio-Coal Agglomeration and High-Fluidity Coking Coal …
Metallurgical coke is obtained by carbonization of coking coal blends up to ~1100 °C [].During carbonization, softening, swelling, evolution of volatiles, shrinking and, finally, re-solidification to obtain coke occur [].Within the plastic range of approximately 350–550 °C, fluidity is induced by breaking the carbon bonds and forming a plastic state, …

AP 42 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".

Kinetic modelling of coking coal fluidity development
Coal plasticity is a phenomenon directly affecting the creation of coke structure. It is very much a time- and temperature-dependent transformation of the coal matrix, which allows changing the physical phase from solid to liquid-like and again into solid of different properties. The coking process, particularly in a plasticization temperature …

Environmental Control and Emission Reduction for Coking Plants
By-product coking plants are comprised of single oven chambers, being 12 to 20 m long, 3 to 8 m tall, and 0.4 to 0.6 m wide, in which the input coal is heated up indirectly. Several chambers are grouped to form one battery (multi-chamber-system; Fig. 4). A single battery may consist of up to 85 ovens.

What is a Coke Oven? (with pictures)
A coke oven is a device used to produce coke, a product that is derived from coal. The mixing and heating of bituminous coal at temperatures ranging from around 1832° to 3632°F (1000° to 2,000°C) within the airless oven yields the coke byproduct. This device is a crucial part of the coke-making process. Coke is a solid remainder of ...
