Explanation of Effect of Slurry Density on Limestone Utilization •Maintaining pH and SO 2 removal requires a specific limestone loading (g-limestone/L-slurry) level for the system. •At low density (low concentration of solids in the slurry), a higher concentration of the solids will be limestone. Therefore limestone utilization will be lower.
May 23, 2015· System Function of FGD. (1). Limestone granules are transported to the wet ball mills via weight feeder, and ball mill system grind the granules to make limestone slurry; (2). Flue gas from the boiler will be inducted into the absorber and contact in counter direction with the limestone/gypsum slurry and remove most of SO2, HCL, HF and so on; (3).

Optimizing the grind of the limestone milling system can have a significant positive impact on limestone utilization. However, it is typically not possible to vary the speed of the mill to increase or decrease its capacity. Early generation wet FGD systems used thickeners for primary dewatering and rotary drum filters for secondary dewatering.
