Alternative fuels in cement manufacturing: Modeling for process
During direct operation, the flue gases are quenched and the pseudo air may be reduced. Since in most cases, the fuel kiln/mill gases are separately treated from the kiln/soil mill gases, the fuel mill may be operated well below its design capacity when AFs are used, leading to lower volume of gases to the respective APCS.

Mercury emission characteristics and mechanism in the raw mill …
During the mill-on mode, the flue gas passed through the raw mill and dust collectors, and a significant decrease in the concentration of mercury emissions was found, which was reduced to 5.3 μg/Nm 3-19.7 μg/Nm 3 at the stack. Thus, the raw mill and dust collector showed significant mercury removal effect during the mill-on mode.
