Coal Types, Uses and Formation

There are four types of coal peat, lignite, bituminous and anthracite. Each type has different proportions of carbon and thus, have different uses. Peat This type of coal has less than 40% to 50% of carbon, while the remaining is moisture. This makes it difficult for us to ignite and cannot be easily used. Lignite This type of coal has 40
