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.

• Mill fineness sample collection is always done under stable and defined conditions. Mills are set for normal operation and no change over are scheduled. • Coal lab staff collecting fineness sample is immediately informed in event of any disturbance in normal operation.
The end result is that pulverizer fineness at the lower loads increases. On pulverizers with >75% passing 200 Mesh fineness at full load, minimum load fineness can be as high as 85% or more. In some instances, an excessive quantity of finely ground coal particles on the bowl acts as a powder lubricant between the roll and bowl.
