Resumo: | The need for investment in improving quality, productivity, and low cost and process energy savings is a growing concern of the ceramist sector. The drying process consists in moisture removal from a material through heating, involving high energy consumption. In this sense, this work aim to study theoretically the drying of hollow ceramic solids with arbitrary shape using a phenomenological mathematical modeling based on the lumped capacitance method. Kinetic results of mass loss and heating of the hollow solid under different operating conditions are presented and analyzed. It was observed that the loss of moisture occurs at a slower rate than the heating rate of the material, and that the shape of the solid and its area / volume relationships strongly affect the heat and mass transport phenomena and that, depending on the intensity, can cause structural damages as cracks, deformations, warping and loss of the product. |

El proceso de secado consiste en eliminar la humedad de un material mediante calentamiento, lo que implica un alto consumo energético. En este sentido, este trabajo tiene como objetivo estudiar teóricamente el secado de sólidos cerámicos huecos y con forma arbitraria utilizando un modelo matemático fenomenológico basado en el método de capacitancia global. Se presentan y analizan los resultados cinéticos de la pérdida de masa y el calentamiento del sólido vertido en diferentes condiciones de funcionamiento. Se observó que la pérdida de humedad ocurre a menor velocidad que el calentamiento del material, que la forma del sólido y su relación área / volumen inciden fuertemente en los fenómenos de transporte de calor y masa y que, dependiendo de la intensidad, pueden ocasionar daños estructurales. como grietas, deformaciones, alabeos y pérdida de producto.A necessidade de investimento na melhoria de qualidade, produtividade, redução de custos e economia de energia de processo é uma preocupação crescente do setor ceramista. O processo de secagem consiste na remoção de umidade de um material através do aquecimento, envolvendo alto consumo de energia. Neste sentido, este trabalho tem como objetivo estudar teoricamente a secagem de sólidos cerâmicos vazados e com forma arbitrária utilizando uma modelagem matemática fenomenológica baseando-se no método da capacitância global. Resultados cinéticos de perda de massa e aquecimento do sólido vazado em diferentes condições operacionais são apresentados e analisados. Observou-se que a perda de umidade ocorre numa menor velocidade que o aquecimento do material, que o formato do sólido e sua relação área/volume afetam fortemente os fenômenos de transporte de calor e massa e que, dependendo da severidade, pode ocasionar danos na estrutura como deformações, trincas, empenamentos e perda do produto.Research, Society and Development2020-11-25info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1036210.33448/rsd-v9i11.10362Research, Society and Development; Vol. 9 No. 11; e54291110362Research, Society and Development; Vol. 9 Núm. 11; e54291110362Research, Society and Development; v. 9 n. 11; e542911103622525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/10362/9085Copyright (c) 2020 Wanderson Magno Paiva Barbosa de Lima; Eduarda Holanda Silva; Elisiane Santana de Lima ; Ricardo Soares Gomez; Hortência Luma Fernandes Magalhães; Stephane Katherine Barbosa Moura da Silva; Túlio Rafael Nascimento Porto; Antonio Gilson Barbosa de Lima https://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessLima, Wanderson Magno Paiva Barbosa de Silva, Eduarda Holanda Lima , Elisiane Santana de Gomez, Ricardo Soares Magalhães, Hortência Luma Fernandes Silva, Stephane Katherine Barbosa Moura da Porto, Túlio Rafael Nascimento Lima , Antonio Gilson Barbosa de 2020-12-10T23:37:57Zoai:ojs.pkp.sfu.ca:article/10362Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:32:26.130123Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
