Abstract. The use of blends of Eastern and Western low-sulfur coals for cost reduction and emission controls, increased coal fineness to reduce unburned carbon in flyash, and the need for better control of air/fuel ratio to improve overall combustion create increased demands upon the plants existing coal milling system. installation of pulverizer airflow controls and high-efficiency exhauster ...
