Abstract
An improved coal pulverizer classifying system in which the feedpipe and classifier cone are provided with extensions to protect coal flow into the pulverizer from the annular fine-lifting airflow from the pulverizer throat. The feedpipe and cone extensions replace traditional intermittent discharge structure, improving flow through the classifier system and reducing the disruptive effects of the discharge on the annular flow from the pulverizer throat. An adjustable classifier venturi is also provided to adjust the exit angle and exit velocity of the fines leaving the classifier cone by the combustion delivery chute.
