Modeling the pre-breakdown V-I characteristics of an electrostatic precipitator

An Overview of Current-Voltage Characteristics Estimation from Plate-Type Electrostatic Precipitator with Three Sections

The paper presents a theoretical analysis on the dynamic characteristics of the current-voltage characteristics of plate-type electrostatic precipitators (with three fields) from an electric power station. Measures were made with signal conditioning, data acquisition card, and PC. It was found that these characteristics can not be mathematically model, due to their permanent modification (have ...

Power Electronic Modelling and Emulation of an Electrostatic Precipitator

In this paper a power electronic emulation of an electrostatic precipitator is presented. Precipitator power supplies can be tested under real power and operating conditions up to 200 kVA. Energy consumption of the system is very low, because the energy which is drawn by the emulation converter is fed back into the power grid. Therefore, just the power losses have to be provided by the grid. It...

Removal of Serratia marcescens aerosols using an electrostatic precipitator.

We characterized the efficacy of an electrostatic precipitator (ESP) air-cleaner in reducing the concentration of Serratia marcescens in an enclosed space. We used an experimental room (4.5 x 3 x 2.9 m) in which electrostatic aircleaners were located. Two air-cleaners enhanced the equivalent ventilation rates in the chamber by about 3.3 air changes per hour (ACH) over the 2 ACH provided by the ...

Modern High-Voltage Control of an Electrostatic Precipitator

Influence of Gas Composition on Corona Discharge Characteristics in the High Temperature / High Pressure Electrostatic Precipitator

The use of electrical corona discharge opens broad possibilities for effective development of electrostatic precipitators (ESPs). The object of the work is the study of the corona discharge in different gases at high temperature / high pressure (HT/HP) conditions. The studies are carried out in a HT/HP ionizer in the pure synthetic air, N2, He and He-synthetic air and He-N2 gas mixtures. Corona...
