Mapeamento da frequência de uso e características da biomassa florestal utilizada para geração de energia em Lages, SC

Abstract: RESUMOA região de Lages, Santa Catarina, tem sua economia baseada na indústria de base florestal, principalmente de transformação primária, que é caracterizada pelo baixo rendimento e grande produção de ABSTRACTIn the region of Lages, in Santa Catarina state, the economy is based on the forest industry, especially for primary processing, and this is characterized by low yields and high production of waste, constituting environmental problems, logistical and financial support. The use of biomass in co-genera… Show more

“…The ash content obtained for biomass residues of Pinus taeda at age of 14 years and planted in a spacing of 2.5 x 2.5 m is close to that reported by several authors in studies regarding biomass residues of Pinus taeda and Pinus patula (FURTADO et al, 2012;ALMEIDA et al, 2010, respectively). Analyzing chips stored indoors in the industry, we can notice stability in the ash content after 30 days.…”

“…However, the highest calorific value was observed at 150 days (4,813 kcal.kg -1 ), followed by the 180 days of storage (4,781 kcal.kg -1 ). In this regard, Furtado et al (2012) point out that the chemical composition of the material, the amount of lignin, cellulose and extractives, and the biomass composition, concerning the amount of wood and bark, may affect the calorific value significantly. Such variation is a common condition when it comes to wood residues from timber harvesting, which has varying types of materials, such as wood, thin and thick branches, and needles.…”

“…Sistemas de geração e co-geração (termelétricas) que utilizam biomassa florestal para a geração de energia tem como padrão o valor mínimo de 1900 kcal.kg -1 como mencionam Furtado et al (2012). O poder calorífico superior das falhas foi menor que o valor apresentado por Oliveira et al (2010) para falha de pinhão, e menor comparativamente a outros tipos de biomassa, incluindo a madeira, como pode ser visualizado na Tabela 3.…”

“…Protásio et al (2011) support this statement, as Brazil has great availability of biomass residues from agriculture and forestry. However, the use of biomass residues depends on a careful evaluation of the available quantity of material, its quality, a marketing analysis of competing uses and an evaluation of available technologies for energy transformation, among other technical, economic, social, and environmental issues (FURTADO et al, 2012;. KIM et al, 2011).…”
