The high temperatures created by ...
Glossary
Coke Oven: A chamber of brick or other heat-resistant material in which coal is heated to separate the coal gas, coal water, and tar. The coal gas and coal water fuse together with carbon and the remaining ash, forming a hard residue commonly referred to as coke. Coke is primarily used in steel production. There are two types of coke ovens: (1 ...

The use of petroleum coke in coal-fired power plants is on the rise. This fuel source is usually produced as a byproduct of oil refining, and contains high levels of carbon. When burned in coal-fired power plants, petroleum coke can produce higher levels of emissions than traditional coal. However, there are some benefits to using petroleum ...
Coking coal of the United States—Modern and historical coking coal
Coking coal, or metallurgical coal, has been produced in the United States for nearly 200 years. Coking coal is primarily used in the production of coke for use in the steel industry, and for other uses (for example, foundries, blacksmithing, heating buildings, and brewing). Currently, U.S. coking coal is produced in Alabama, Arkansas, Pennsylvania, ia, …
What is Petcoke? And What is it Used For?
High grade petcoke which is low in sulphur and heavy metals can be used to make electrodes for the steel and aluminum industry. But the majority of petcoke manufactured globally, approximately 75-80%, is of a much lower grade, containing higher levels of sulphur and heavy metals and is used solely as fuel.
