An experimental study has been made of fluid transients in the pumping system of a limestone flue gas desulfurization (FGD) system operating at a large southeastern utility. Pressure transducers were installed on both the discharge and suction sides of three 600 hp centrifugal pumps that, along with a fourth standby pump, were installed in parallel and provided a total of 78,000 gpm of slurry to the FGD tower. The purpose of the experiments was to determine the magnitude of the fluid transients in the system and to observe changes in the fluid transients resulting from changes in the amount of air trapped in the system prior to startup. The amount of trapped air was controlled by making changes in system startup logic. The results show many interesting features of such large scale pumping systems and implications of these results to pumping system design are discussed.
