“…Possibly, such increases are related to the increase of fixed carbon content provided by torrefaction, as shown by Rodrigues (2009) andPincelli (2011). Comparing Figures 2 and 3, it can be noticed that torrefaction influenced in wastes particle size reduction.…”

The experiment consists in the realization of timber wastes torrefaction at a final temperature of 280 ºC, with heating rates of 0,5 ºC.min -1 , with 1 hour permanence in the final temperature. Three different types of wastes were analyzed by composition. Moisture content, bulk density, torrefied mass yield, gross calorific value, particle size, and physical and mechanical resistance were determined. Except the moisture content, the remaining variables were evaluated before and after torrefaction. The results indicated that torrefaction increased the wastes energy density . The torrefied material yield was influenced by the particle size. Bulk density was reduced; however, the mass reduction was higher than the volume reduction. The calorific value was increased for all types of torrefied wastes. Torrefied wastes friability was higher compared to in natura wastes.

“…Conforme a Tabela 1, o tratamento a 12% de umidade apresentou os maiores valores de carbono fixo (30,57%) e cinzas (0,19) implicando em menor valor de materiais voláteis. As cinzas, representa os constituintes inorgânicos que não participam do processo de combustão da biomassa (Brand, 2010) onde baixos teores de cinzas diminuem as influências negativas sobre o poder calorífico (PINCELLI, 2011). Já o carbono fixo tem uma relação direta com o poder calorífico, o qual em maiores quantidades resulta na queima mais lenta e melhora energeticamente a biomassa .…”

“…In general, forest activity is characterized by large production of residues in the production process, , which can be differentiated into three main groups: forest harvesting material (or harvest residue), residues generated in wood processing, and wood from energy forests . The forest harvesting residue is formed by branches, leaves, bark, and part of the wood that is not used, such as the tips and the remaining material of the cut. , …”

Energy Assessment of Wood Pyrolysis Coproducts for Drying and Power Generation

et al. 2017

Carbonization is the process in which wood is heated in a closed environment with a controlled amount of air, producing charcoal as a solid product and secreting water vapor, organic liquids, and noncondensable gases. The burning of these gases generates energy that can be used for the drying wood to be carbonized or for generation of electric power in the carbonization plant itself. The present study had the purpose to conduct an energetic survey of the fractions from charcoal production process, aiming to subsidize and to encourage the technological development of equipment for energetic use of carbonization gases. The results showed that the energy contained in noncondensed gases and in pyroligneous liquid corresponds to a total of 31% of the wood energy used. Two scenarios of synchronizing four kilns were studied in pyrolysis, and a maximum and constant potential of 9.7 MW was obtained in scenario 2. The gas burner was efficient in the emission control, because it reduced CO and CH4 in the ranges of 97–99% and 68–91%, respectively. Thus, the gas burner is a promising technology for reduction of greenhouse gases and generation of thermal energy from carbonization coproducts.
