Coal: Anthracite, Bituminous, Coke, Pictures, Formation, Uses
Coal is an organic sedimentary rock that forms from the accumulation and preservation of plant materials, usually in a swamp environment. Coal is a combustible rock and, along with oil and natural gas, it is one of the three most important fossil fuels.
Coal - Simple English Wikipedia, the free encyclopedia
Under suitable conditions, plant material is transformed step by step into Peat is not yet coal.; Lignite (brown coal) is the dirtiest coal, is about 60%-70% carbon, and is used as fuel for electric power generation.Jet is a compact form of lignite that is sometimes polished and has long been used as an ornamental stone.; Sub-bituminous coal is used as fuel for steam-electric power generation.
Coal: Post-Fuel considers coal as material - MaterialDistrict
Coal: Post-Fuel, a project by designer Jesper Eriksson, considers an alternative, future use of coal as a material, re-evaluating the material's image as dirty fuel.. According to Eriksson, "In the instance of coal, the meaning we have assigned to it is that of a fossil fuel for energy production.

Coke (fuel) - Wikipedia
Coke is a fuel with a high carbon content and few impurities, made by heating coal in the absence of air. It is the solid carbonaceous material derived from destructive distillation of low-ash, low-sulphur bituminous coal.Cokes made from coal are grey, hard, and porous.While coke can be formed naturally, the commonly used form is synthetic. The form known as petroleum coke, or pet coke, is ...
