  • Fineness an overview ScienceDirect Topics

    The fineness of the milling product and the capacity of the pulverizer are strictly connected. With increased fineness grows the overall circulation rate of coal in the mill, coal retention time and the flow resistance. As a result, the maximum mill capacity decreases and the rate of change of operational parameters of the furnace system deteriorates.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
