Coal Grinding. To achieve good combustion and satisfactory flame formation, coal needs to be dried and ground to a proper degree of dryness and fineness. Drying of moisture in coal is achieved normally by ducting part of the kiln exhaust gas through the mill with inlet temperatures of up to 300°C. Inert kiln exhaust gases with oxygen content ...

The increasing coal feed rate will influence strongly to the capacity and performance of the pulverizer. Decreasing performance of the pulverizer will cause that the quality of coal fineness will be less than 70% of 200 mesh. It will result delay of coal combustion and finally the metal temperature at the Secondary superheater increase.

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.

With near 0% remaining on the 50-mesh sieve, at least three points are needed on the Rosin-Rammler Chart to plot the fineness results. Four sieves of 50, 100, 140, and 200 mesh are recommended for fineness sampling. Fuel line fineness should be 75% or more passing a 200-mesh screen and a maximum of 0.1% remaining on the 50-mesh screen.

As feed rate decreased, fineness improved. Note that better than ±10% fuel balance is not achieved until better than 70% passing 200 Mesh is achieved. When >10% fuel imbalance is observed, burner lines with higher fuel flows typically have less desirable fineness. Burner lines that have less fuel typically have better coal fineness.
