Bituminous Coal Characteristics and Applications

sometimes referred to as coking coal is used in the process of creating coke necessary for iron and steel production Coke is a rock of concentrated carbon created by heating bituminous coal to extremely high temperatures without air This process of melting the coal in the absence of oxygen to remove impurities is called pyrolysis

How Does a Coal Power Plant Work?

Thermal-based power plants can produce electricity from coal or other fuel sources The coal-fired process requires three different steps to turn energy released from burning coal to generating electricity for consumption Coal fired power plants while producing power require a lot of water and produce a lot of pollutants like ash and CO2
