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.

When it comes to grinding raw coal, savings in specific energy consumption can be achieved with vertical roller mills. Specific energy consumption depends on the grindability of the raw coal and the coal meal fineness required. A dynamic separator that ensures high separation efficiency also helps to reduce specific energy use.
