Chapter 2. Basic Factors Controlling Coal Quality and Technological Behavior of Coal
2.1. Introduction
Conventionally, coal is used in processes such as combustion, gasification, and liquefaction and in carbonization for the manufacture of metallurgical coke. Coal and its derivative products are also used as precursors of other materials and in the production of chemicals. Thus, a coal must be characterized before it is used, whether as a single or blended coal. Characterization is performed in order to find out the properties of a coal, to determine its quality, and to predict its technological behavior. Basically there are two characteristics that influence the use of coal: its composition and its rank. Coal composition is in turn represented ...
