The AGMA 6EP (ISO 320) gear oil recommended by the OEM failed to provide adequate lubrication and protection based on oil analysis results and gearboxRaw 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.Pulverizers 101: Part I - POWER Mag,01-08-2011· Pulverizers prepare raw fuel by grinding it to a desired fineness and mixing it with the just the right amount of air before sending the mixture to boiler burners for combustion.
