“…At an electrode separation (d > 5 cm), the starting voltage of negative corona is (15*d Kv) where d is the separation between the electrodes in cm." As demonstrated in [14], this corona production field is determined experimentally, then the relationship between the electric field and corona effect is represented by…”

The electrostatic precipitator (ESP) is an extensively used system in metallurgical industries and the generation of power to decrease the release of dust in the flue gas. In the design of the Electrostatic precipitator unit, gas emission uniform distribution is expected to fulfil its best aggregation performance. Programming Logic Controller (PLC) is a controller for industrial process automation and self-monitoring. A lot of industries utilized PLC to automatically control the entire process with less involvement from the human and to evade errors. In this paper, A mathematical model for Electrostatic precipitator from physical parameters and analysis has been developed. The controller is built depending on this model using the basic principle of a well-known A Proportional Integral Derivative (PID) controller to control the high voltage of the Electrostatic precipitator (ESP) by adjusting the opening of voltage and current by applying analogue signals (4-20 mA) from output cards of the PLC. The simulation results paved the way to build a practical system. building the mathematical model by using the Identification Toolbox of MATLAB® Version 9.6. The system was built using Allen Bradley PLC. The effect of control parameters (PID) in the case of voltage or current has been studied to demonstrate the efficiency of the model for the precipitator and observer in the case of the control system for the Al-Tahady ESP. The PID controller was built and the best values for the Electrostatic Precipitator controller are (K P =2.3904, K I =3.5382, K D =0.3). PID controller reduces steady-state errors.

“…Plasma air purification attracts widespread attention in recent years, mainly related with corona discharges under an air supply channel. Plasma air purification has been developed in many applications, including electrostatic precipitation [32][33][34][35][36][37][38][39][40], industrial gas exhaust treatment [41][42][43][44], and indoor air purification [45][46][47][48][49]. Work groups [35] illustrate that the electric power and the energy loss of corona discharges highly depend on airflow velocities, and corona discharge modes are also related to airflow conditions.…”

Atmospheric pressure discharges are widely used in active airflow control, material synthesis, and air treatment. The key to an optimal application performance lies in how to generate stable and diffuse plasma especially in a large volume and in high-speed airflows. This chapter presents the study of repetitive nanosecond volume discharges under high-speed airflows. The volume discharge strongly depends on the airflows, and the corresponding discharge modes vary from filament to diffuse modes with addition of airflows. The role of airflows provides negative effects on discharge currents as well as discharge densities. Moreover, a type of discharge device with upstream and downstream structure is proposed to demonstrate that charged particles produced by the upstream discharge are transported to the downstream zone and play a pre-ionization and enhanced effect to the downstream discharges.
