Coal Mill - an overview ScienceDirect Topics

B. Miller, in Ultra-Supercritical Coal Power Plants, 2013. Sulfur content. 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. As the overall sulfur ...
