BALANCING OF PULVERIZED COAL FLOWS TO BURNERS …

In a typical vertical spindle pulverizer (Figure 1), raw coal is fed through a central coal pipe at the top of the pulverizer and falls by gravity to the rotating grinding table, ... The number of outlet pipes on a typical vertical spindle mill varies between 2 and 8. The distribution of primary air throughout the piping network is

Rotating Throat and Deflector

An optimum pulverizer throat configuration is a big deal. The pulverizer throat area and configuration must be right to minimize coal rejects at the optimum air/fuel ratio; must help turn down to a minimum load without "rumble"; and must be configured to not have quiescent zones that contribute to mill fires.
