Resumo: | he objective of this research was to evaluate torrified and fresh pellets produced from Pinus waste wood, used for direct generation of thermal energy. The compaction of Pinus sp. waste wood from lumbermill was performed in a pelletizer with a planar array of 8 mm. Roastings were performed in an electric furnace, type muffle, stabilized at final temperatures of 220 °C and 250 °C for 30 min. The following pellets properties were determined: apparent and unit energy density, bulk density, energy bulk density, immediate chemical composition (volatile materials, ash and fixed carbon), high heating value and moisture. It was observed an increase in high heating value and reduction of moisture content of torrified pellets. However, the gain in calorific value was less than the mass loss of the pellets after roasting, reducing the energy densities of the pellets. The pellets raw have marketing potential in European countries such as Germany, Austria and Sweden. The methodology used for roasting is not suitable for pellets heat treatment. However, further research on pellet roasting in a wider temperature and residence time range is recommended, in order to define parameters that optimize their energetic properties. |

O objetivo deste estudo foi avaliar pellets torrificados e in natura,produzidos a partir da madeira residual de Pinus, destinados ao uso bioenergético. A compactação da madeira residual de Pinus sp. oriunda de serraria foi realizada em uma peletizadora com matriz plana de 8 mm. As torrefações foram realizadas em forno elétrico, tipo mufla, estabilizado em temperaturas finais de 220 °C e 250 °C por 30 min. Foram determinadas as seguintes propriedades nos pellets: densidades aparente e energética unitárias, densidades a granel e energética do granel, composição química imediata (materiais voláteis, cinzas e carbono fixo), poder calorífico superior e umidade. Observou-se aumento do poder calorífico superior e redução do teor de umidade nos pellets torrificados, contudo, o ganho em valor calórico foi inferior à perda de massa dos pellets após a torrefação, reduzindo assim a densidade energética dos pellets. Os pellets in natura apresentam potencial de comercialização em países europeus, como Alemanha, Áustria e Suécia. A metodologia utilizada para torrefação não é indicada para o tratamento térmico de pellets. Porém, recomendam-se novas pesquisas sobre torrefação de pellets em uma faixa mais ampla de temperatura e tempo de residência, visando determinar parâmetros que otimizem as propriedade energéticas.Embrapa Florestas2015-12-31info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/84310.4336/2015.pfb.35.84.843Pesquisa Florestal Brasileira; v. 35 n. 84 (2015): out./dez.; 435-442Pesquisa Florestal Brasileira; Vol. 35 No. 84 (2015): out./dez.; 435-4421983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/843/456Copyright (c) 2015 Thiago de Paula Protásio, Paulo Fernando Trugilho, Humberto Fauller de Siqueira, Isabel Cristina Nogueira Alves de Melo, Carlos Rogério Andrade, José Benedito Guimarães Juniorhttps://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessProtásio, Thiago de PaulaTrugilho, Paulo Fernandode Siqueira, Humberto Faullerde Melo, Isabel Cristina Nogueira AlvesAndrade, Carlos RogérioGuimarães Junior, José Benedito2017-11-15T17:19:35Zoai:pfb.cnpf.embrapa.br/pfb:article/843Revistahttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/PUBhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/oaipfb@embrapa.br || revista.pfb@gmail.com || patricia.mattos@embrapa.br1983-26051809-3647opendoar:2017-11-15T17:19:35Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
