Resumo: Low air velocities are not fully explored yet in the field of electrostatic precipitation due to the size limitations of the industrial devices, but they had provided high collection efficiencies for nanoparticles in studies in laboratory scale. In order to contribute to the science of electrostatic precipitation, a full 3² factorial design of experiments was performed to evaluate the effect of operating conditions (applied voltages from -8.0 to -8.2 kV and air velocities from 1.67 to 19.9 cm s-1) on the overall mass efficiency of electrostatic precipitation of KCl nanoparticles (5.94–224.7 nm). Response Surface Methodology was used to assess the range of operating conditions that provide the highest efficiencies. The highest percentual efficiency (99.870 ± 0.008) was obtained for -8.2 kV and 6.67 cm s-1. A polynomial model fitted well the experimental data (R² = 0.99217).

Visando contribuir com a ciência de precipitação eletrostática, um planejamento fatorial 3² completo foi realizado para avaliar o efeito de condições operacionais (voltagens de -8.0 a -8.2 kV e velocidades do ar de 1.67 a 19.9 cm s-1) sobre a eficiência mássica global de precipitação eletrostática de nanopartículas de KCl (5.94–224.7 nm). Metodologia de Superfície de Resposta foi usada para obter a faixa de condições operacionais que forneciam as maiores eficiências. A maior eficiência percentual (99.870 ± 0.008) foi obtida para -8.2 kV e 6.67 cm s-1. Um modelo polinomial ajustou bem os dados experimentais (R² = 0.99217).Universidade Federal de Viçosa - UFV2020-10-20info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufv.br/jcec/article/view/1087910.18540/jcecvl6iss4pp0547-0554The Journal of Engineering and Exact Sciences; Vol. 6 No. 4 (2020); 0547-0554The Journal of Engineering and Exact Sciences; Vol. 6 Núm. 4 (2020); 0547-0554The Journal of Engineering and Exact Sciences; v. 6 n. 4 (2020); 0547-05542527-1075reponame:The Journal of Engineering and Exact Sciencesinstname:Universidade Federal de Viçosa (UFV)instacron:UFVenghttps://periodicos.ufv.br/jcec/article/view/10879/6084Copyright (c) 2020 The Journal of Engineering and Exact Scienceshttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessEstarque de Oliveira, AlessandroGiovana Guerra, Vádila2021-02-23T20:11:08Zoai:ojs.periodicos.ufv.br:article/10879Revistahttp://www.seer.ufv.br/seer/rbeq2/index.php/req2/oai2527-10752527-1075opendoar:2021-02-23T20:11:08The Journal of Engineering and Exact Sciences - Universidade Federal de Viçosa (UFV)false
