Summary of Coal Mill Controls. 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 ...
