WEBCoal goes from mining to a preparation plant for cleaning and then it is usually shipped by train to the power plants. Most coal in the U. S. is burned to heat water into steam. The power plants where the fossil fuel is burned are called thermal because they use heat energy. Coal burning produces emissions of carbon dioxide and sulfur.

WEBCoal traditionally has been a key part of the cokemaking process. The coal is crushed and ground into a powder and then charged into an oven where it is heated to approximately 1800°F in the absence of oxygen. As the oven is heated, the coal begins to melt so most of the volatile matter such as oil, tar, hydrogen, nitrogen and sulfur are removed.
