  • Low-Rank Coal Grinding Performance Versus Power Plant ...

    Dec 31, 2008  This project studied the relationship between PSD and power plant efficiency, emissions, and mill power consumption for low-rank high-volatile-content Alaskan coal. The emissions studied were CO, CO{sub 2}, NO{sub x}, SO{sub 2}, and Hg (only two tests). The tested PSD range was 42 to 81 percent passing 76 microns.

    Jun 01, 2008  The grinding power consumption of the mill is 227 kW, calculated from Eq. (11) when the mill is running under stable conditions. A motor with 110 kW standard power was used for the mill in its initial design. In semi-industrial tests, however, the mill stopped for lack of power when approaching the specification load gradually.
