ABSTRACT:
An improved coal pulverizer classifying system including a classifier cone extension to protect coal flow into the pulverizer from the annular fine-lifting airflow from the pulverizer throat. The classifier cone extension replaces 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. The pulverizer feedpipe outlet is located in the classifier cone extension, but above the throat of the extension to prevent interference between the feedpipe and the flow of coal through the extension. In a preferred form an adjustable clearance cone is mounted for vertical adjustment on the lower end of the feedpipe.
