Apr 25, 2017· Combustion occurs when fossil fuels are burned, and the elements in the fossil fuels oxidize, or combine with oxygen. When coal is burned, the carbon oxidizes to form carbon dioxide, or CO2. Similarly, nitrogen becomes nitrous oxide, or NO2, and sulfur becomes sulfur dioxide, or SO2. The mineral content found in coal and oil become ash.

If coal is high in sulfur or other impurities, it is washed with a water or chemical bath, removing up to 40 percent of inorganic sulfur in the coal. Not all coal is prepared using the same process. Highsulfur coal commonly undergoes washing to meet environmental regulations, while lowsulfur coal is often crushed and resized without being washed.

Jan 14, 2019· Bituminous coal contains the mineral pyrite, which serves as a host for impurities such as arsenic and mercury. Burning the coal releases trace mineral impurities into the air as pollution. During combustion, approximately 95 percent of bituminous coal''s sulfur content gets oxidized and released as gaseous sulfur oxides.
