Mar 30, 2020· 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. Peat, when burned, produces a lot of smoke and a large flame and therefore is rarely used as a heat source. Stage two of the coal formation process is ...
