issues with coal pulverizers

If you want to learn about our products , please call or write mail consultation.

In some instances in which pulverizer fineness has been achieved, higher fineness levels have caused certain pulverizers to “rumble”; especially at the lower pulverizer loads. As pulverizer load is decreased and primary airflow decreases to maintain the proper air/fuel ratio, the velocities across the pulverizer throat also decrease
