摘要：

This work aimed to evaluate the energy quality of wood and charcoal obtained from the stem and root of the genus Eucalyptus spp. From the wood, the physical, chemical and energetic properties were evaluated. For the charcoal produced in ovens of the carbonization furnaces model in the industry and produced in a muffle furnace, the physical, chemical and energetic properties were evaluated. Based on the analysis of technological properties, wood from the root has higher basic density (731.45 kg m-3) and lignin content (26.44%), however, the fixed carbon content and higher calorific value of the root (17.54% and 4547.75 kcal kg-1) were lower than for the stem wood (21.36% and 4730.82 kcal kg-1). It is recommended to use the wood from the root, both for direct burning and for the production of charcoal. The charcoal obtained in the industry, compared to that produced in muffle, presented higher energy quality.
