Three-phase high voltage power supply design for electrostatic precipitator based on phase sequence self-adaption and redundant spark detection
The three-phase power supply has the advantages of small voltage ripple, balance three-phase load and high output power. It is suitable for application in the large electrostatic precipitators of the sintering machine head and the coal fired boiler. This paper designs the three-phase power supply based on phase sequence self-adaption and redundant spark detection. The winding connection mode of Y-Y and the full-bridge rectification circuit are used. This is beneficial to the energy saving, and the energy saving effect is also analyzed. In addition, the three-phase intermittent control is realized. The comparative experiments of voltage boosting between the three-phase power supply and the single-phase power supply demonstrate that the proposed design is effective.
Electrostatic Precipitator Power Supply- A Review
The aim of this work is to analyze and understand the operation of various power supplies evolved for the application of Electrostatic Precipitator (ESP). From this work it is possible to identify the problems arouse in the power supply section and the way they get resolved can be understand. Also the problems still need to be solved has to be identified and the possible solutions has to be formed.
Electrostatic precipitator handbook
The operation of oil- and coal-fired power stations in our environmentally conscious era requires the efficient removal of dust from the exhaust gases. Electrostatic precipitators accomplish this task successfully. This book aims to provide a practical 'hands on' treatment of electrostatic precipitation for the power station engineer. It is also an excellent introduction to the subject for students. The first six chapters explain the basic principles of both tube- and parallel-plate precipitators, and the processes of dust charging and collection. There follows a discussion of the properties of dust, with emphasis on the problems encountered with both high- and low-resistivity dusts. Later chapters deal with electrode design and alignment, and the question of safety for power station personnel. Finally, strategies for the maintenance of existing equipment and the procurement of new precipitators are evaluated.
