Evaluation of Biomass Properties for the Production of Solid Biofuels

Abstract

The efficient use of biomass as fuel requires prior knowledge of the composition and properties of the material in order to be able to develop technologies for its efficient combustion while ensuring that emissions of pollutants remain within acceptable limits. Therefore, the analysis of the physical and chemical properties of these materials is essential in order to evaluate their potential for energy purposes. Given the need for improved understanding of biofuels, this study aimed to characterize biomass waste obtained from the manufacturing process of wood panels and urban waste for the production of solid biofuels. Biomass wastes were characterized in terms of their physical and chemical properties. Wastes that presented the poorest qualities for use as fuels were eucalyptus bark, industrial waste, and sweepings, which had high ash contents and low calorific values. The remaining wastes showed satisfactory characteristics for use as solid biofuels.

Recovering Wood Waste to Produce Briquettes Enriched with Commercial Kraft Lignin

“…The ash content, another important parameter to heating values, was similar to eucalypt wood (0.1% -0.4%) according to Pereira et al [35], Borges et al [67], Morgan et al [68], Veiga et al [69] and Silveira [70]. The ash content is not desirable for energy application collaborating for decreasing heating value [74] [79] [80]. The ash content is also undesirable for the operation of boilers, where the biomass can be burned for converting it into energy [15] [81] [82], since ash is responsible for generating incrustations, corrosion, unscheduled stops for maintenance, for example.…”

Caracterização da madeira de Prosopis juliflora utilizada na indústria de cerâmica vermelha no semi-árido brasileiro

“…Assim, para o uso da madeira como fonte de energia nas indústrias de cerâmica vermelha, toras com elevados teores de umidade proporciona um aumento no tempo de transferência de calor da superfície para o centro da peça durante a queima da lenha, elevando o gasto energético pelo acréscimo na quantidade de energia necessária para a evaporação da água e, consequentemente menor quantidade de energia é liberada dentro dos fornos da cerâmica que reduz a eficiência do processo na produção de telhas e tijolos. Além disso, uma maior quantidade de água presente na madeira, aumenta os custos com transporte das toras e reduz o poder calorifico do material (CARASCHI et al, 2019).…”
