Coal, Kentucky Geological Survey, University of Kentucky

Most, if not all, coals are tested prior to being used. Some markets require specific quality characteristics for the process in which the coal is used, and environmental regulations also require knowledge of a coal's quality. Some products also require analysis of physical characteristics of coals for handling or processing.

Coal - Wikipedia

Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed if dead plant matter decays into peat and over millions of years the heat and pressure of deep burial converts the peat into coal.

Sub-bituminous coals are the second division of low-rank coals.They are transitional between lignite and bituminous coal. In the U.S. rank classification, sub-bituminous coals and their subdivisions (A, B, C) are supposed to be based on calorific value.By ASTM standards, sub-bituminous coals have calorific (heating) values of 8,300 to 11,500 Btu/lb (ASTM, 2014).

Coal | Facts, Uses, & Types | Britannica.com

Apr 25, 2019· Coal is defined as having more than 50 percent by weight (or 70 percent by volume) carbonaceous matter produced by the compaction and hardening of altered plant remains—namely, peat deposits. Different varieties of coal arise because of differences in the kinds of plant material (coal type), degree of coalification (coal rank), and range of impurities (coal grade).
