The efficiency of electrostatic precipitators at thermal power plants can be enhanced by increasing their active volume by increasing the height of the electrode systems to 15 – 18 m. However, when increasing height, deviations in the flatness of the surface of the collecting electrode are enlarged up to 22.5 mm, leading to an increase in emissions up to 3 times or more. Experiments were carried out to establish the causes of deviations in the electrodes of domestic electrostatic precipitators to include the technology of profiling the collecting electrode elements, the method of assembling the elements together in height, the symmetry of the element cross-section relative to the center of gravity, as well as the method of fastening between the elements and the shaking beam. Based on an analysis of factors affecting the flatness of collecting electrodes, as well as bench and industrial testing, a collecting electrode having minimal surface deviations from the plane was developed. As a result of the industrial application of the collecting electrode created using an innovative manufacturing technology, including profiling of the collecting electrode elements and assembling them into the electrode, the efficiency of the electrostatic precipitator was increased.
