This balance in the mill caused better combustion in the upper furnace while balanced mills made for a more balanced furnace. Optimized burner belt combustion contributed to lower LOI, slagging, fouling, and reduced spray flows. The next step in this plant is to upgrade the mill to improve coal fineness to 75% passing a 200mesh sieve.

Combustion tuning of a pulverized coal boiler begins with balancing the air and fuel flows in the coal pipes from the pulverizers to the burners. Note that each of the coal pipes is a different length. On most boilers, burners are also present on the opposite side of the furnace, adding to the air/fuelbalancing challenges. Courtesy:
