Abstract Introducing electrostatic effect is a new approach for the development of wet flue gas desulfurization technology.And the electrostatic spraying characteristics of lime slurry is the key of lime slurry electrostatic spraying desulfurization technology.With the application of 3D particle dynamic analyzer(3D-PDA),lime slurry electrostatic spraying test set was established to describe the distributing characteristics of velocity and particle size for the first time.The different charging voltages and lime slurry flow variables were measured.With the coherent data manipulation method,detailed measurement for a lime slurry electrostatic spraying nozzle has been completed in conjunction with velocity and particle size characteristics.The results indicate that the introducing of electrostatic effect can enhance lime slurry spraying quality and improve the distributing uniformity of lime slurry droplet velocity and particle size.The effect is obvious when charging voltage is 5 kV to 10 kV.lime slurry droplet;charging;PDA;average velocity of axes;average velocity of radial;average particle size
