Abstract. CO 2 emissions from coal power generation could be reduced by maximizing the amount of torrefied biomass that can be used in pulverizedcoalfired power plants. In this study, to evaluate the milling performance of coal and torrefied wood pellets (TPs), various blend ratios were tested using a benchscale roller mill.
