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 glassy material in most bituminous coal is vitrinite, composed of macerals derived primarily from woody plant tissue.
Coal is composed of old plant material that was chemically altered over the course of millions of years. The coal contains energy from sunlight that the plants captured and stored via ...
These classifications are based on the amount of carbon, oxygen, and hydrogen present in the coal. Coal is defined as a readily combustible rock containing more than 50% by weight of carbon. Coals other constituents include hydrogen, oxygen, nitrogen, ash, and sulfur. Some of the undesirable chemical constituents include chorine and sodium.

Coal ash includes a number of byproducts produced from burning coal, including: Fly Ash, a very fine, powdery material composed mostly of silica made from the burning of finely ground coal in a boiler. Bottom Ash, a coarse, angular ash particle that is too large to be carried up into the smoke stacks so it forms in the bottom of the coal furnace.
Dec 22, 2012· Coal is a black or brownishblack sedimentary rock that can be burned for fuel and used to generate is composed mostly of carbon and hydrocarbons, which contain energy that can be released through combustion (burning). Coal is the largest source of energy for generating electricity in the world, and the most abundant fossil fuel in the United States.
Coal is defined as a readily combustible rock containing more than 50% by weight of carbon. Coals other constituents include hydrogen, oxygen, nitrogen, ash, and sulfur. Some of the undesirable chemical constituents include chorine and sodium. In the process of transformation (coalification), peat is altered to lignite, lignite is altered to ...
Coal is formed mainly by geological processes. It is a type of fossil fuel created from the remains of dead plants many years ago. It has been classified as a nonrenewable energy source. Further, coal is composed of elements like carbon, sulphur, hydrogen, nitrogen and oxygen amongst others. Different Uses of Coal
Coal is made from the remains of plans and trees that lived about millions of years ago. They delayed and get buried to the ground and were compacted under rock layers. It is a hard brown or black rocklike mineral substance that is used for burning to generate heat.
Coal is mainly composed of carbon, oxygen and hydrogen. Humans use coal in the manufacturing of steel, in generating electricity, as a source of heat, as a liquid fuel and in the manufacturing of ...

Coal is a combustible, sedimentary, organic rock, which is composed mainly of carbon, hydrogen and oxygen. It is formed from vegetation, which has been consolidated between other rock strata and altered by the combined effects of pressure and heat over millions of years to form coal seams.
Most of the coal mined in the United States is transported to a power plant, crushed to a very small particle size, and burned. Heat from the burning coal is used to produce steam, which turns a generator to produce electricity. Most of the electricity consumed in the United States is made by burning coal.
Coal was, however, used only on a limited scale until the early 18th century, when Abraham Darby of England and others developed methods of using in blast furnaces and forges coke made from coal. Successive metallurgical and engineering developments—most notably the invention of the coalburning steam engine by James Watt —engendered an ...
