RESUMO: O objetivo deste estudo foi caracterizar as propriedades do carvão vegetal produzido em fornos retangulares industriais, por meio da análise de componentes principais. Para isto, foram amostrados três estoques industriais de carvão vegetal, provenientes dos Forno I e II, com capacidade volumétrica de 500 e 180m 3 de madeira, respectivamente. Determinaramse as características do carvão vegetal, como granulometria média, teor de finos, densidade a granel e composição química imediata. Foram realizadas as análises descritiva e de componentes principais com o objetivo de avaliar as relações entre as propriedades do carvão vegetal. De forma geral, para ambos os fornos, observou-se que a granulometria média teve uma relação negativa com teor de finos, enquanto a densidade a granel, uma relação positiva. No entanto, a relação entre o carbono fixo e teor de cinzas para o Forno I foi direta, e para o II foi inversa. As propriedades do carvão vegetal dos fornos retangulares, de forma geral, apresentam média assimetria. O carvão vegetal possui alta variabilidade nas suas propriedades, no entanto, é possível, por meio de ajustes operacionais, melhorar a qualidade do carvão para o consumidor final.Palavras-chave: análise de componentes principais; carbono fixo; granulometria média Characterization of charcoal produced in industrial rectangular furnaces ABSTRACT:The objective of this study was to characterize the properties of charcoal produced in industrial rectangular furnaces, using principal components analysis. For this, three industrial stocks of charcoal were sampled from Furnace I and II, with volumetric capacity of 500 and 180m 3 of wood, respectively. The average particle size, fines content, bulk density and proximate composition were determined. Descriptive analysis and principal component analysis were carried out to evaluate the relationships between charcoal properties. In general, for both furnaces, it was found that the average particle size showed a negative relationship with fines content as the bulk density had a positive relationship with the content of fines. However, the relationship between the fixed carbon and ash content for Furnace I was direct, and for Furnace II was inverse. The charcoal properties of the rectangular furnaces, in general, present a medium asymmetry. The charcoal has a high variability in its properties, however, it is possible, by operating adjustments to improve the quality of coal to the consumer.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
