International Journal for Research in Engineering
2018-9-24 Optimized mill air to fuel ratio. Minimum fineness level: greater than or equal 75 percent passing 200 mesh and less than or equal 0.1 percent remaining on 50 mesh. Mill-to-mill mass air and fuel balance within ±5% of the mean.
Pulverizer Fineness
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.

Optimisation of coal fineness in pulverised-fuel boilers
2017-11-15 An additional problem is a prolongation of the residence time of coal in the mill with increasing fineness, which influences the output of the mills and the boiler. The loss due to unburned combustibles (UBC) in slag and fly ash (S UBC ) depends almost entirely on the contribution of coarse fractions in the PF, while the energy consumption for
