Thermal Coal
Thermal coal is also used in some of the processes for ironmaking especially in the production of direct reduced iron (DRI) and in the smelting reduction processes for the production of hot metal (HM). Thermal coal is a complex heterogeneous substance. Hence, it has no fixed chemical formula. Its characteristics and hence its CV …
What is coal used for? | U.S. Geological Survey
Coal is primarily used as fuel to generate electric power in the United States. In coal-fired 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 high-pressure steam, which drives a turbine, which produces electricity. In 2019, about 23 percent of all electricity in …
Coal prices and outlook
In 2022, the average delivered price of coal to the electric power sector was $44.51 per short ton, which includes both spot and contract purchases. A more expensive coal is used to make iron and steel. In addition to producing electricity, coal is also used to produce coal coke, or coke, which is used in smelting iron ore to make steel.
Coal | Properties, Formation, Occurrence and Uses
Coal is a non-clastic sedimentary rock.They are the fossilized remains of plants and are in flammable black and brownish-black tones. Its main element is carbon, but it can also contain different elements such as hydrogen, sulfur and oxygen. Unlike coal minerals, it does not have a fixed chemical composition and crystal structure.Depending …
Coal & electricity
Steam coal, also known as thermal coal, is used in power stations to generate electricity. First coal is milled to a fine powder, which increases the surface area and allows it to burn more quickly. In pulverised coal …

The Coal Facts: thermal coal vs. metallurgical coal
Metallurgical coal or coking coal is used in the process of creating coke necessary for iron and steel-making. Coke is a porous, hard black rock of concentrated carbon that is created by heating ...
Coking Coal vs. Thermal Coal
Coking coal has a relatively low heating value due to its higher impurity content, making it less efficient for direct combustion. In contrast, thermal coal has a higher heating value, …
What You Should Know About Metallurgical Coal
Metallurgical coal differs from thermal coal, used for energy and heating, by its carbon content and its caking ability. Caking refers to the coal's ability to be converted into coke, a pure form of carbon that can be used in basic oxygen furnaces. Bituminous coal—generally classified as a metallurgical grade—is harder and blacker.
Metallurgical Coal vs. Thermal Coal
In conclusion, metallurgical coal and thermal coal are two distinct types of coal with different compositions, uses, and environmental impacts. Metallurgical coal is essential …

Coal facts
This energy can then be converted into other forms of useful energy, such as electricity. Coal used for electricity generation is commonly referred to as thermal coal. Higher carbon and lower moisture coal is often used to make steel. Coal used for steelmaking is commonly referred to as metallurgical or coking coal.
