The Coal mill performance monitoring - SlideShare
At lower PA flows the pulverized coal is in danger of falling out of suspension and laying out in the coal conduits, possibly resulting in fire or explosion. Minimum line velocity is thus affected by conduit size, number of conduits, altitude and temperature. Minimum line velocity is usually targeted at about 3000 fpm (15.24 m/sec) at sea level.
