-Pipe to pipe fuel balance within ± 100/0 of the pulverizer's mean pipe fuel flow. -Pipe to pipe dirty air velocity balance within ±5% of the pulverizer's mean pipe dirty air velocity. -Minimum coal fineness level of 75% passing 200 mesh and less than 0.1 % remaining on 50 mesh. -Pulverizer to pulverizer mass air and fuel balance within ± 5%.
Figure 4 compares a conventional vertical table type pulverizer with a ball tube mill pulverizing system with crusher dryer. The table type pulverizer allows high temperature air to reach the coal charge. The ball mill system with crusher dryer normally reduces the inlet temperature to less than the auto ignition point of the coal charge.
