Coal Grade Defined Term

A blend of two or more bituminous coals is usually required to make coke. Pulverized coal is a coal that has been crushed to a fine dust in a grinding mill. It is blown into the combustion zone of a furnace and burns very rapidly and efficiently. Slack coal usually refers to

and coal blends (Crelling, 2008; Ward and Surez-Ruiz, 2008). The rank and maceral composition of a coal affects the strength of the coke produced as well as its expansion/contraction characteristics, which ultimately may impact on wall pressure in a slot-type coke oven (Clendenin, 1969). For coke stability prediction, the ratio of reactive to

Coke Reactivity and Characterisation ACARP

In trying to relate coke quality to its ultimate use in the blast furnace, one of the primary attributes of the coke quality is the coke strength. The Coke Reactivity test is a highly regarded measure of the performance of coal. This test has two components; the Coke Reactivity Index (CRI) and the Coke Strength after Reaction (CSR).
