What Coal Is | ND Studies Energy Curriculum
Coal is a dark brown or black solid fossil fuel that was formed tens to hundreds of millions of years ago by the partial decomposition of land vegetation under increased pressure and temperature in an oxygen-free environment.; The three fossil fuels – coal, petroleum, and natural gas were formed in a similar way by heat and pressure, but petroleum and natural gas were formed from plants and ...

and coal over millions of years of time. There are mainly three types of coal, namely anthracite (hard coal), bituminous (Soft coal) and lignite (brown coal). Anthracite coal has maximum carbon (90%) and calorific value (8700 kcal/kg.) Bituminous, lignite and peat contain 80, 70 and 60% carbon, respectively. Coal is the most abundant fossil fuel in the world.

Anthracite coal generally has the highest heating value per ton on a mineral-matter-free basis. It is often subdivided into semi-anthracite, anthracite, and meta-anthracite on the basis of carbon content. Anthracite is often referred to as "hard coal"; however, this is a layman''s term and has little to do with the hardness of the rock.

Anthracite Coal Characteristics and Applications
· Anthracite contains a high amount of fixed carbon—80 to 95 percent—and very low sulfur and nitrogen—less than 1 percent each. Volatile matter is low at approximately 5 percent, with 10 to 20 percent ash possible. Moisture content is roughly 5 to 15 percent. The coal is slow-burning and difficult to ignite because of its high density, so ...

Bituminous coal | coal classification | Britannica
Bituminous coal is dark brown to black in colour and commonly banded, or layered. Microscopically, three main groups of macerals (individual organic constituents of coal) can be recognized: vitrinite, liptinite, and inertinite.The glassy material in most bituminous coal is vitrinite, composed of macerals derived primarily from woody plant tissue.
· Anthracite is considered the most ecologically friendly type of coal. In fact, it burns completely and practically does not fume. It leaves no more than 9% of ash after burning, and during the burning process it emits much less than other types of coal – only 3-5% volatile pollutants, depending on the anthracite grade.
Anthracite is the most desirable type of coal because it contains more energy than other types and it is also the most environmentally friendly of them because of purity. Unfortunately, only approximately 1% of all the coal is anthracite. So we also burn bituminous coal, lignite (brown coal), and even peat which is the source material of coal.

Types of coal, lignite, subbituminous coal, anthracite, bituminous coal. The rank of coal is based on the degree to which the original plant material has been transformed into carbon and can be seen as a rough indication of how old the coal is: the older the coal the higher the carbon content (generally).

Brown coal is a solid pit coal formed from peat. The youngest type of coals contains 65-70 % carbon and is brown in colour. It is used as a domestic fuel and a chemical feedstock. This coal has a high water content (43 %) and therefore a low heat of combustion. It also contains a large number of volatile substances (up to 50 %).
