The limestone slurry preparation system is widely used in the wet Flue Gas Desulfurization（FGD） system. The performance of a limestone slurry preparation system has a great influence on the operating reliability of the wet FGD system. The insufficient output of the limestone slurry preparation system is a very typical problem in wet FGD systems. The performance of the limestone slurry preparation system is influenced by many factors. In this paper, factors resulting in an insufficient output of the limestone slurry preparation system were analyzed, such as the feeding system, the limestone wet grinding mill, the limestone slurry hydrocyclone, the measuring instruments for the limestone slurry preparation system, and the analyzing techniques, etc. The reasons of the insufficient output of the limestone slurry preparation system were analyzed and corresponding treatments were suggested. In addition, some reasonable advice was proposed for the operating of limestone slurry preparation system.
