Most pulverizers require 40 to 70% of their full-load primary air requirements at their minimum output level. In addition, the PA/PC mixture traveling to the burners must be transported at a minimum of 3000 ft/min (15 m/s). This velocity serves to prevent the coal particles from dropping out of suspension in horizontal runs of coal pipe.
