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 most logical reasons are that a the heat generated in conditioning and pelleting make the feedstuffs more digestible by breaking down the starches, b the pellet simply puts the feed in a concentrated form, and c pelleting minimizes waste during the eating process.

Coal Volatility Explosion frequency increases with an increase in volatility content, but this trend is as weak statistically as the others. These statements and the appearance of Figure 2 remain unchanged even if a dry, ash free basis is used for volatility. Coal Moisture Explosion frequency remains unchanged with increasing coal moisture.
Explosions consistently occur when the coal air mixture is leaner than normal, either when initating coal feed on mill start-up, stopping coal feed on shutdown, or when equip- ment problems cause inadvertent loss of feed. Upon loss of feed to a pulverizer, the coal air mixture in the system becomes leaner and the coal
