Coal

Coal is a solid combustible mineral which was gradually formed after complex biochemical and physicochemical changes by the ancient plants buried underground. As the most widely distributed fossil energy in the world, coal has a wide range of applications. However, due to the combustion of coal will produce a lot of pollutants, such as sulfur oxide, nitrogen oxide and particulate matter, which has a serious impact on the environment and human health, so clean coal preparation technology came into being. Clean coal powder preparation technology is a process that subdivides coal into micron or even nanometer powder materials, and reduces pollutant emissions during combustion by changing the form and chemical properties. At present, clean coal powder is often used as fuel or raw material in coal-fired power generation, industrial boilers, coal gasification, and coal-fired batteries.
