Coal Mill - an overview ScienceDirect Topics

Sulfur in coal can affect power plant performance in several ways. Sulfur in the form of pyrite (FeS 2 ) can lead to spontaneous combustion and contributes to the abrasion in coal mills ; therefore, if a lower quality coal containing pyrite is used in place of the design coal it can lead to problems.
