WEBAug 1, 2016 · Thus, pulverized coal flow to boiler cannot be reflected effectively, and can only be reflected by coal feed rate [17]. Given the existence of grinding in the mill, raw coal is grinded into pulverized coal and then sent into the boiler. In this case, mill capacity (that is, pulverized coal flow) relative to load command has certain hysteresis.
