Various Stages In The Processing Of Coal

What Are the Four Stages in Coal Formation?

2020-3-30 · Follow Us: The four stages in coal formation are peat, lignite, bituminous and anthracite. Each of these stages must be completed for coal to form. Stage one in coal production is peat. Peat is a fibrous substance that is oxidized by water and carbon dioxide. When a plant dies, and stays under water, it builds up an accumulation of peat.

Formation of Fossil Fuels – Coal and Petroleum

Coal Formation Stages. The formation of coal is a four-stage process, depending on the conditions to which the plant debris was subjected. More the heat and pressure to which vegetation is subjected, better is the quality of coal. Superior quality coal is denser, has more carbon content, contains lesser moisture and has a better calorific value.
