Pulverizer Fineness

Importance of Fineness Higher fineness levels always promote more even distribution of fuel between a pulverizer’s separate burner lines. Better distribution promotes better combustion, inherently lower NOx emissions and lower flyash L.O.I. or carbon content. The graph below illustrates actual test data on a pulverizer with varied fineness.
