Lime slurries are widely used as a sorbent in Spray Dryer Flue Gas Desulfurization systems. In the present General Electric design, a rotary atomizer is employed to break up and disperse the sorbent within the reactor vessel. The purpose of the work reported here was to develop a means for predicting the size distribution of the non-Newtonian lime slurry droplets produced by such devices. A correlation is developed from measurements of water sprays made on two wheels, 101.6mm and 400mm in diameter. This correlation is then successfully extended to cover the breakup of dilute lime slurries (<250 mg/ml) by observing that the viscosity of these non-Newtonian fluids tends asympotically to that of the water carrier at the very high rates of shear that characterize the drop formation process.
