Coal pipe F9 on pulverizer B was the only pipe that met the original plant fuel specification guarantee of 70% passing 200 mesh which is far short of the 75% minimum we use
the coal/ air mixture velocity has slowed and is equal to the flame speed From this we see the importance of maintaining burner operating velocities above the minimum specified by the manufactu
Minimum transport velocities recommended based on coal milling experience are 15 m/s with a specified minimum air temperature at the mill of 60 °C The minimum figure for air velocity<
