How Coal Works

Dec 15, 2021How coal is formed. Coal is formed when dead plant matter submerged in swamp environments is subjected to the geological forces of heat and pressure over hundreds of millions of years. Over time, the plant matter transforms from moist, low-carbon peat, to coal, an energy- and carbon-dense black or brownish-black sedimentary rock.

Metallurgical coal

Metallurgical coal is a primary ingredient in the steel making process. It takes around 770 kilograms of coal to make one ton of steel. Approximately 70% of global steel is produced in basic oxygen blast furnaces. The majority of steel is used in: Construction: like buildings, bridges and infrastructure. Transport: like ships, planes and trains.

The shift to bituminous coal and coke occurred more slowly. In the 1810s, Thomas Lewis was the first to make coke in America, for Isaac Meason's rolling mill constructed at Plumsock and then at Bear Creek Furnace. These early coke furnaces, however, failed due to a weak blast, inferior coal and coke, and inadequate transportation.
