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 180m3 de madeira, respectivamente. Determinaram-se 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.

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 180m3 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.  



Key words:      principal component analysis; fixed carbon; average particle size</abstract>
