Abstract

To achieve the optimum dust removal performance of an electrostatic precipitator, the flue gas should be distributed uniformly over its vertical cross-section. The flow in the upstream flue gas ducts has a significant influence on the downstream gas distribution in the chamber of the precipitator. This paper presents the results of homogeneity assessment of velocity distribution in the ducts and vertical cross-sections of the electrostatic precipitator of unit A1 at the Nikola Tesla thermal power plant in Obrenovac. The measurements confirmed that the reconstruction of the vertical chamber at the front of the precipitator, which was carried out during the overhaul in 2020, effectively solved the problem of the original asymmetric arrangement of the vertical flue gas ducts. Nevertheless, the analysis revealed poor homogeneity of the flow field through the chambers. Therefore, additional measures must be taken to increase the dust removal efficiency of the precipitator.

TPP尼古拉特斯拉A1单元静电除尘器通道和室内速度分布的研究

为了达到静电除尘器的最佳除尘性能，烟气应均匀分布在其垂直截面上。上游烟气管道的流动对下游烟气在除尘器腔室中的分布有显著影响。本文介绍了奥布伦瓦茨尼古拉特斯拉热电厂A1机组电除尘器风管和垂直截面流速分布的均匀性评价结果。测量结果证实，2020年大修期间对除尘器前部垂直腔室进行的改造，有效解决了原有垂直烟气管道布置不对称的问题。然而，分析表明，通过腔室的流场均匀性很差。因此，必须采取额外的措施来提高除尘器的除尘效率。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
