What are the different types of coal? American Geosciences

The coal formation process involves the burial of peat which is made of partly decayed plant materials deep underground. The heat and pressure of burial alters the texture and increases the carbon content of the peat which transforms it into coal a type of sedimentary rock. This process takes millions of years. Types or “ranks” of coal are determined by carbon content. There are four

Coal fired power plant - Energy Edu ion

Many coal plants are mine mouth which means the plant was put where the coal mine is so the coal doesn& 39;t need to be transported by train. Once unloaded the coal is then pulverized into a fine powder by a large grinder. This ensures nearly complete burning of the coal in order to maximize the heat given off and to minimize pollutants.
