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.

COAL MILL/PULVERIZER IN THERMAL POWER PLANTS SHIVAJI CHOUDHURY. 2. 1.Introduction Coal continues to play a predominant role in the production of electricity in the world, A very large percentage of the total coal is burned in pulverized form. Pulverized coal achieved its first commercial success in the cement industry.
Accumulations of debris or coal anywhere in the pulverizer will increase the chance of a mill fire. The pyrite removal chute should be inspected often to ensure rejected material is removed from the under bowl area. Stoppage of pyrite chute flow can cause debris and-or coal to back-up into the primary air ducting.
