COAL
Coal is a combustible, sedimentary, organic rock, which is composed mainly of carbon, hydrogen and oxygen. It is formed from vegetation, which has been consolidated between other rock strata and altered by the combined effects of pressure and heat over millions of years to form coal seams. Coal is a fossil fuel and is far more plentiful than oil or gas, with around 109 years of coal remaining worldwide. Not only does coal provide electricity, it is also an essential fuel for steel and cement production, and other industrial activities.
Coal is the world's fastest growing major fuel.
Uses of coal
The most important uses for coal are as a fuel in energy production and in the process industry, and as a reducing agent in the manufacture of steel.
Coal was the world’s most important source of energy up until the 1960s, when oil took over the role. Coal is nevertheless still the most important fuel in the production of electricity. Over 40 per cent of the world’s electricity is generated in coal-fired power plants, and 25 per cent of all human-generated energy today is based on coal.
The other main area of use for coal is in various chemical processes, of which iron and steel manufacture are the most important. Coal is usually refined into coke first, by the driving off of volatile matter in a separate process. The coke is then used as a reducing agent in the purification of iron ore and the refining of iron into steel.
Coal is also used in the manufacture of cement, artificial fertilisers, plastics, tools and pharmaceutical products, and as an additive in the casting of various metal alloys.
World production of bituminous coal in 2008 totalled 5.8 billion tonnes, while lignite production totalled 950 million tones.
On a global basis, coal is the largest fossil energy reserve. Known coal reserves are spread throughout more than 100 countries, with the largest reserves in the USA, the former Soviet Union, China, Australia and India. At current production levels, the world’s coal reserves will last for approximately 200 years.
