Coal classification Coal is classified into three types as follows, even there is no clear demarcation between them: 1. Anthracite 2. Bituminous 3. Lignite. The Coal is further classified as semi-anthracite, semi-bituminous and sub-bituminous. the anthracite is the oldest coal from a geological perspective.

Where does the coal go after it leaves the mine? The coal is shipped by train or barge to its destination. The coal may be refined before shipping. Washing with water or a chemical bath to remove some impurities. When the coal arrives at the power plant, it is pulverized into a …
Classification of coal based on volatile matter and cooking power of clean material Sponsored Links Coal is a readily combustible rock containing more than 50 percent by weight of carbonaceous material formed from compaction and indurations of variously altered plant remains similar to those in peat.
2.4.2 Different types of coal combustion techniques Combustion of Coal Combustion may be defined as the rapid high temperature complicated chemical reaction of oxygen with carbon, hydrogen and sulphur of coal. These reactions follow mainly four steps. 1. Formation of coal-oxygen complexes with evolution of heat. 2.
Coal Classification There are two main ways for classifying coal - by rank and by type. Coal Rank Coal Types Coal Rank : The degree of 'metamorphisrn' or coalification undergone by a coal, as it matures from peat to anthracite This has an important bearing on its physical and chemical properties, and is referred to as the 'rank' of the coal.
These components which are called macerals are the basic and relatively homogenous organo-petrographic entities of coal, which by their chemical composition and physical characteristics determine properties and utilization of coal The classification is based either on similar origin (leptinite group) and/or on the difference in preservation (e ...
Chapter 7 COAL If we as a nation are to benefit in the future from our enormous, low-cost coal reserves, a variety of efforts are necessary to (1) develop and demonstrate new "clean coal" technologies; (2) reduce uncertainty over environmental regulation and allow electric power
"Coal in truth stands not beside but entirely above all other commodities. It is the material energy of the country- the universal aid, the factor in everything we do with coal, almost any feat is possible; without it we are thrown back into the laborious poverty of early times" (DiCiccio, 1996).
Coal classification There are many compositional differences between the coals mined from the different coal deposits worldwide. The different types of coal are most usually classified by rank which depends upon the degree of transformation from the original source (i.e., decayed plants) and is therefore a measure of a coal's age.
Coal classification: Coal classification, any of various ways in which coal is grouped. Most classifications are based on the results of chemical analyses and physical tests, but some are more empirical in nature. Coal classifications are important because they provide valuable information to commercial users and to researchers.

4.1 This classification establishes categories of coal based on gradational properties that depend principally on the degree of metamorphism to which the coal was subjected while buried. These categories indicate ranges of physical and chemical characteristics that are useful in making broad estimates of the behavior of coal in mining, preparation, and use.
