The important elements of pulverizer performance are fineness, fuel distribution, coal (pyrites) rejects, and primary airflow calibrations. Optimizing pulverizer performance is a prerequisite for optimum furnace combustion. About three-fourths of the 13 Essentials are pulverizer, primary air, and fuel line related.

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 higher pulverizer d/p.

This inventive control system provides improved pulverizer response by controlling fuel flow into the furnace rather than into the pulverizers. Improved response is also obtained since the proper amount of over/under feeding is controlled to effect faster changes in the mill storage level of the pulverizer.

The STORM ® pulverizer throat bypass is designed to reduce unneeded pressure drop, improve airflow dynamic, pulverizer efficiency, and reducing low load rumble. The design intent is to bypass airflow from the underbowl and introduce just above the throat. The bypass reduces mill differential pressure by providing a secondary path of air, introducing it to the mill above the grinding zone.
