Raw Coal Spillage Or "Pyriting"

Coal 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.
