• PF velocity between mill and burners has to be between 18 m/s and 23 m/s. (At 18 m/s PF tends to settle in PF pipes which could cause blockages and at velocities above 23 m/s the wear rate due to erosion within these pipes is too high.) • Coal mass flow equal to OEM (original equipment manufacturer) specification.
