what the process to get coal

natural sciences grade 9 grade 7 9 workbooks. coal found in sedimentary rock, is crushed into the appropriate size and used as fuel for electricity generation or the iron making process. lumps of coal can be used directly as a fuel. however some coal is first washed to make it into 'high grade coal'. it can also be sorted into various sizes, depending on what the fuel is required for.

Coal National Geographic Society

Dec 22, 2012  Coal is a black or brownish-black sedimentary rock that can be burned for fuel and used to generate electricity.It 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.

How is coal formed?

In the process of transformation (coalification), peat is altered to lignite, lignite is altered to sub-bituminous, sub-bituminous coal is altered to bituminous coal, and bituminous coal is altered to anthracite. Lignite - is the lowest rank of coal - which means that it has the lowest heating value and lowest carbon content. Although lignite ...

Coal Our energy. Coal was made out of the ancient plants, 300 million years ago, even before dinosaurs, when huge plants started sedimentation in swamps In millions of years that followed, mud was frothed over remains, transforming in that process huge heat in to a pressure, and all these factors combined gave ideal conditions for coal’s “birthing place”...

Coal formation - Energy Education

Coal is a solid, black, readily combustible fossil fuel that contains a large amount of carbon-based material - approximately 50% of its weight. The formation of coal takes a significant amount of time (on the order of a few million years), and the first coal-bearing rock units appeared about 290-360 million years ago, at a time known as the Carboniferous or "coal-bearing" Period.

Coal fired power plant - Energy Education

The conversion of this coal to the end goal of electricity is a multi-faceted process: The coal must be unloaded from the train. Traditional ways of doing this require the use of cranes picking up the coal from the cars, however newer plants have the floor underneath the train tracks drop away, allowing the coal to be dropped into underground containment.
