accomplished during grinding in ballandtube mills or roller mills. While thermal energy for drying can be supplied by exhaust gases from separate, directfired coal, oil, or gas burners, the most efficient and widely used source of heat for drying is the hot exit gases from the pyroprocessing system.

Oxygenenriched combustion is the most promising CO 2 emission reduction technology for coal burning. However, the sharp increase in CO 2 and SO 2 concentrations in flue gas after oxygenenriched combustion poses a new challenge to the subsequent wet flue gas desulfurization (WFGD) system. In this study, limestonebased dualloop WFGD technology was used to solve this problem.
