Coal Mill - an overview | ScienceDirect Topics

To summarize the coal mill controls, they may be divided basically into two major categories:. 1. To control the quality of coal being sent to the burners located on the furnace walls. The word quality here means the temperature and fineness of the PF. The set temperature values are dependent on the percentage of volatile matter that exists in the main fuel.

The Storm Approach to Coal Pulverizer Optimization

Once normal coal flow is applied to the mill, a full mill test should be conducted. This should include isokinetic coal sampling and dirty airflow measurements through each fuel line to determine air fuel balance and coal fineness. Primary airflow “Hot-K” calibrations of the primary airflow measuring element should also be conducted.
