Fieldscale investigation of pulverized coal mill power ...

Twenty fieldscale tests were conducted in a 28 MW pulverized coal power plant in Healy, Alaska, to examine mill power consumption in relation to coal grind size. The intent in this fieldscale study was to verify if grind size truly impacted power consumption by a detectable amount. The regression model developed from the data indies that grind size does impact mill power consumption, with ...
