2021.1.14 The source of nearly 50 pct of the sulfur content of an average bituminous coal used by an electric utility is pyrite (FeS2); pyrite is a component that is not chemically bound to the coal and, therefore, can be removed by physical separation methods. Removing 50 to 70 pct of the pyrite would accomplish only a 25- to 35-pct reduction in

Read MoreCoal dribble or spillage is raw coal that is rejected through the pulverizer’s pyrite discharge. This is caused when the velocity across the pulverizer throat is too low to maintain suspension of coal. Air velocities through the pulverizer throat should be 7,000 to 7,500 Fpm when calculated on a free jet basis.
