IMPROVE YOUR PULVERIZER PERFORMANCE

4. Lower air flow results in better fineness amp; less erosion. 5. Lower air flow can result in more pyrites but fewer burner eyebrows. 6. Lower air flow means and a greater tendency to plug with wet coal. 7. Lower air flow leaves more reserve fines in the pulverizer. 8. Also note that lower air flow leaves a deeper bed depth of coal and thus a ...
