Abstract: EffEct of anti-corrosion coatings of corona ElEctrodEs on sElEctEd opErating paramEtErs of industrial ElEctrostatic prEcipitators WpłyW poWłok antykorozyjnych ElEktrod ulotoWych na WybranE paramEtry EksploatacyjnE ElEktrofiltróW przEmysłoWych* The problem of corrosion protection of electrostatic precipitators used in the energy industry, during its construction or moderni-zation is of vital importance. Several months construction period and the period of time elapsed from the end of construction to operation promotes corrosion of its components. Significant impact on the electrical parameters of an electrostatic precipitator performance has the corrosion phenomena of its emission components, which are the corona electrodes. Manufacturers do not apply any corrosion protection coating on electrostatic corona electrode for fear of worsening their emissivity. This paper presents the results of comparison of emission properties of corona electrodes with and without corrosion protection coatings. Rode and mast type electrodes were studied. The analysis of the results was performed using a statistical method based on the time-series model. The obtained results clearly show that the use of anti-corrosion coating does not impair the electrical parameters of corona electrodes. Corrosion protection can be used both during the modernization as well as during the construction of new electrostatic precipitators.
