Frequent Questions about the Beneficial Use of Coal Ash ...

Uses of Coal. Coal is a typical conventional solid fuel that has been exploited as an important source of fuel by humankind for thousands of years. The main use of coal is as fuel for electric power plants for which more than 50% of the coal produced in the world is used. The simplest use of coal is to burn it for heat.

Coal | National Geographic Society

Of the three fossil fuels in common use – natural gas, petroleum, and coal – the United States has far more coal than gas and petroleum (compare Figures 7-1, 8-1 and 9-1). This suggests that, when supplies of gas and petroleum become scarce, it would be possible to turn to coal as our major fossil fuel energy resource.

Coal begins as peat, which consists of loosely consolidated layers of various mixtures of plant and mineral matter. Peat accumulates in wetlands called "peat swamps," "bogs," or "mires." In this report, the term "peat swamp" is used to indicate a peat-forming wetland. Figure 6 is a photograph of the Okefenokee Swamp, which is a modern ...

Coal - Origin of coal | Britannica

There are four major types (or "ranks") of coal. Rank refers to steps in a slow, natural process called "coalification," during which buried plant matter changes into an ever denser, drier, more carbon rich, and harder material. Anthracite: The highest rank of coal. It is a hard, brittle, and black lustrous coal, often referred to as ...

How Does a Coal Power Plant Work? - Bright Hub Engineering

Although peat is used as a source of energy, it is not usually considered a coal. It is the precursor material from which coals are derived, and the process by which peat is formed is studied in existing swamps in many parts of the world (e.g., in the Okefenokee Swamp of Georgia, U.S., and along the southwestern coast of New Guinea).

Generating Electricity from Coal - Duke Energy

This drives off some of the volatile materials and concentrates the carbon content. Coke is then used as a high-carbon fuel for metal processing and other uses where an especially hot-burning flame is needed. Coal is also used in manufacturing. If coal is heated the gases, tars, and residues produced can be used in a number of manufacturing ...

Coal oil is made by heating cannel coal with a controlled amount of oxygen, a process called pyrolysis. Coal oil was used primarily as fuel for streetlights and other illumination. The widespread use of kerosene reduced the use of coal oil in the 20th century. Coking coal is used in large-scale industrial processes.
