Turbine classifiers for coal pulverizers IEEE Conference

Turbine classifiers for coal pulverizers IEEE Conference

Abstract: Coal pulverizers have utilized a static classifier to generate the desired product fineness which could be effectively burned in a kiln, furnace or boiler. Now there is interest in obtaining a finer product that can enhance the burning efficiency in a coal fired kiln. This is important in light of the increased use of petroleum coke rather than conventional coal.
