Pipe-to-pipe dirty airflow balance within ±5 percent of the mean airflow. 3. Optimized mill air to fuel ratio. 4. Minimum fineness level: greater than or equal 75 percent
airflow between actual measured flow and the indicated flow ranged from 3.5% to upwards of 30%. Since primary airflow plays such a crucial role in the performance of the pulveriser and the pulveriser's capability to provide optimum fuel balance and fineness to each burner, primary airflow must be accurately controlled and managed. As
Operating a pulverizer with airflow above specification is considered less then optimal; the higher airflow will increase internal wear in the fuel pipe and pulverizer. It can also cause a reduction in the pulverized coal fineness. 6. Operating a pulverizer with the pyrite discharge gate closed is prohibited because it prevents the normal ...
