A SUMMARY OF EXPERIENCES RELATED TO COMBUSTION

Pulverizers usually utilize classifiers, which employ the principles of centrifugal separation to reject coarse coal particles back to the pulverizer for regrinding. The “Swirl” imparted by centrifugal classification facilities separation of coarse and fine particles. • Poor fineness results in a very stratified mixture leaving the classifier
