  • Coal electricity World Coal Association

    Steam coal, also known as thermal coal, is used in power stations to generate electricity. Coal is first milled to a fine powder, which increases the surface area and allows it to burn more quickly. In these pulverised coal combustion (PCC) systems, the powdered coal is blown into the combustion chamber of a boiler where it is burnt at high temperature (see diagram). The hot gases and heat ...

    About 8000 Mt of coal are produced annually, about 90% of which is hard coal and 10% lignite. As of 2018 just over half is from underground mines. More accidents occur during underground mining than surface mining. Not all countries publish mining accident statistics so worldwide figures are uncertain, but it is thought that most deaths occur in coal mining accidents in China: in 2017 there were 375 coal mining related deaths in China. Most coal mined is thermal coal (also called steam coal as it is used to make st

    IntroductionPropertiesUsesHistoryFormationResourcesMiningProcessingCoal is classified as a sedimentary rock. It is a common non-renewable fuel used mainly in the production of electricity. It is a fossil fuel because it forms from dead plant matter. The quality of coal depends on how it formed; as the organic matter is subjected to greater heat and pressure, the carbon content increases.
