Raw Coal Spillage Or "Pyriting"

Pulverizer spillage is usually caused by air velocity across the pulverizer throat that is too low (<7,000 Fpm) to prevent coal from spilling through the throat annulus into the pulverizer pyrite section. Air velocity across the vane wheel annulus must be in the range of 7,000 Fpm to 7,500 Fpm to maintain suspension of raw coal of ¼" to 1" in size.
