First, the coal is mined from underground and ground into a fine powder so that it burns more easily. Take a look at the rest of the process below in the diagram from Energy Explorer. Now that you have an idea about the process coal goes through to become electricity, watch this VIDEO to see an animation of how a coal fired plant works.

The U.S. coal industry serves a vital role in the nation’s economy by producing fuel for more than half of its electricity. Despite the industry’s importance, industry financial data for 2005—the strongest year for the coal industry in recent years—shows that it is a relatively small industry with revenues totaling $20 billion to $25 billion and net income between $1 billion and $2 ...

In surface mining, the ground covering the coal seam (the overburden) is first removed to expose the coal seam for extraction. The elements of a surface mining operation are (1) topsoil removal and storage for later use, (2) drilling and blasting the strata overlying the coal seam, (3) loading and transporting this fragmented overburden material (called spoil), (4) drilling and blasting the ...

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.

In the Fischer-Tropsch process, coal is converted to gaseous products at temperatures in excess of 800 °C (1470 °F), and at moderate pressures, to produce synthesis gas. C + H 2 O → CO + H 2 In practice, the FT reaction is generally carried out at temperatures in the range 200-350 °C (390-660 °F) and at pressures of 75-4000 psi; the ...
