The gas velocity characteristics within an ESP play an important role in overall ESP performance. If local gas velocities are too high, then the aerodynamic forces upon the particles can overwhelm the electrostatic force generated by the collecting surfaces and electrodes. This leads to degradation in collection efficiency. Similarly, if the local velocities are too low, then the collecting surface is not been adequately utilized and the potential of particulate build up in the ESP inlet and outlet ductwork increases. For these reasons, proper design of flow control devices within ESP is critical. Typically, this design is performed utilizing a flow model of ESP to optimize the geometry of turning vanes, baffles, and perforated plates.
