Plugged Burner Lines
High primary airflow can cause poor coal fineness, poor fuel balance, non-optimum combustion and consequently poor boiler performance. Low primary airflow can cause burner pulsation, windbox fires, fuel line pluggage, inability to maintain mill outlet temperature, roll skidding (rumbling), pulverizer fires and excessive pyriting.
