What You Should Know About Metallurgical Coal


Metallurgical coal, also known as coking coal, is used to produce coke, the primary source of carbon used in steelmaking. Coal is a naturally occurring sedimentary rock formed over millions of years as plants and other organic materials are buried and subjected to geological forces.

Difference Between Coal and Coke | Compare the Difference ...


May 14, 2012· • Coke is produced from bituminous coal. • Coke burns with no smoke whereas coal burns with smoke. Therefore, coke is better as a fuel than bituminous coal itself. • Therefore, coke is used as a substitute for coal in domestic environments. • Water content in coke goes t zero at the end of the coking process, but coal contains water.

Coal: Anthracite, Bituminous, Coke, Pictures, Formation, Uses


Coke production remains an important use of coal. Coke is produced by heating coal under controlled conditions in the absence of air. This drives off some of the volatile materials and concentrates the carbon content. Coke is then used as a high-carbon fuel for metal processing and other uses where an especially hot-burning flame is needed.
