Uses of Coal. Coal is a very widely used natural resource because of its unique characteristics. Because of its affordability, it is used in several countries for electricity and power generation. Generally, powdered coal is used to create steam, which in turn generates electricity with high pressure.

Coal ash, also referred to as coal combustion residuals or CCRs, is produced primarily from the burning of coal in coalfired power plants. 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.

Because coal is only mined in a few regions of the country, it typically needs to be transported before being burned in a power plant. Wyoming's Powder River Basin coal, for example, is shipped by rail to power plants as far away as Georgia. Trains move roughly 70 percent of the coal that's transported in the United States every year ...

Charcoal. Wood pile before covering with turf or soil, and firing it ( c. 1890) Charcoal is a lightweight black carbon residue produced by strongly heating wood (or other animal and plant materials) in minimal oxygen to remove all water and volatile constituents. In the traditional version of this pyrolysis process, called charcoal burning ...

Incorporating coal as a filler to fabricate polymer composites or as a modifier to enhance the properties of polymeric materials is an important strategy to extend the nonenergy application and sustainability of coal. The literature shows that different process pathways can be used to develop coal/polymer composites owing to different enduses.

Coal is primarily used as fuel to generate electric power in the United States. In coalfired power plants, bituminous coal, subbituminous coal, or lignite is burned. The heat produced by the combustion of the coal is used to convert water into highpressure steam, which drives a turbine, which produces electricity. In 2019, about 23 percent of all electricity in the United States was ...
