Lime technical requirements: according to the content of lime in Shandong Metallurgical protactinium oxide supplier with lime, quicklime and lime powder into calcium lime and magnesia lime; slaked lime according to the content of magnesia slaked lime powder into calcium lime powder magnesia dolomite lime powder and lime powder. Effect of limestone composition of wet flue gas desulfurization performance: Limestone other impurities on the stable operation of the wet FGD system will bring greater impact, thereby reducing the performance of FGD systems. Shandong Metallurgical FGD system is running with lime supplier, although there will be the addition of excess lime limestone slurry Shandong Metallurgical suppliers, pH values ??still declining, the pH value of the loss of control of the phenomenon, the desulfurization efficiency will fall, that is, into limestone slurry "blind spots" or "bad syrup."
