Coal Rank - an overview | ScienceDirect Topics

The ASTM coal rank classification is based on a number of parameters obtained by various prescribed tests, which include calorific or heating value, volatile matter, moisture, ash, and fixed carbon (Figure 4.10). Calorific or heating value of coal is defined as heat energy released as it undergoes complete combustion with oxygen. Volatile ...

ASTM D388 - 18 Standard Classification of Coals by Rank

Note 1: Coals rich in inertinite or liptinite (exinite), or both, cannot be properly classified because, in those macerals, the properties that determine rank (calorific value, volatile matter, and agglomerating character) differ greatly from those of vitrinite in the same coal. Often such coals can be recognized by megascopic examination. In North America, these coals are mostly nonbanded ...

Coal Geology | Geoscience Australia

Coal is broadly separated into brown and black which have different thermal properties and uses. Brown coal (lignite) has a low energy and high ash content. Brown coal is unsuitable for export and is used to generate electricity in power stations located at or near the mine. Black coal is harder than brown coal and has a higher energy content.

What are the types of coal? - USGS

There are four major types (or "ranks") of coal. Rank refers to steps in a slow, natural process called "coalification," during which buried plant matter changes into an ever denser, drier, more carbon rich, and harder material. The four ranks are: Anthracite: The highest rank of coal.
