FLUE GAS DESULFURIZING MATERIAL AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a flue gas desulfurizing material which can be manufactured without passing through a washing stage and which is remarkably low in forming properties and inexpensive for an absorbent of sulfur oxides in the flue gas used for a wet flue gas desulfurzing device and to device its manufacturing method. SOLUTION: A limestone ore is subjected to dry rough crushing, and the roughly crushed matter is classified to obtain coarse grains having >= about 0.5 mm size which is then subjected to dry grinding.
