Coal - University of Colorado Boulder

The coal industry is also concerned about the carbon dioxide that is produced when coal is burned. Carbon from burning coal reacts with air to form carbon dioxide. When carbon dioxide and other gases, such as those emitted from automobiles, accumulate in the earth's atmosphere, they form a shield that allows the sun's light and heat in, but ...

Coal Combustion Wastes - Ground Truth Trekking

Background. Burning coal produces a variety of solid wastes known as coal combustion waste or coal combustion products. These include coal ash (fly ash and bottom ash), boiler slag, and flue-gas desulphurization products. In 2007 over 120 million tons of these wastes were produced in the US, of which approximately 44% was reused in other …

Coal and Air Pollution | Union of Concerned Scientists

Coal has long been a reliable source of American energy, but it comes with tremendous costs because it is incredibly dirty. The same chemistry that enables coal to produce energy—the breaking down of carbon molecules—also produces a number of profoundly harmful environmental impacts and pollutants that harm public health.

Coal | Student Energy

Coal can be burned for heating or to produce electricity. To convert thermal coal to electricity, it is first milled to a fine powder, which increases the surface area and allows it to burn more quickly. The hot gases and heat energy produced from combustion converts water into steam to run a turbine and generator ...
