Peabody Coal Company, under contract to the National Center for Air Pollution Control, has investigated sulfur-dioxide removal from a pilot moving grate furnace stack gas by the addition of calcium bearing dry additives to the flue gas and to coal before burning. Effects of additive feed rate, residence time, temperature, and particle size on sulfur-dioxide removal were studied, and calcination, calcium-oxide utilization, and additive efficiency were determined.
