Resumo: The objective of the present was to characterize the quality of briquettes produced with fines of vegetable coal and bamboo residues, under different formulations. Specific gravity density, bulk density mass, moisture content and speed or rate of thermic degradation were evaluated. Compressive strength and rotation test were applied to the briquettes. Superior and inferior calorific values from briquettes were estimate by adjusted equations. Briquettes produced with the highest percentages of vegetable coal fines presented higher specific gravity, bulk density, ash content and fixed carbon. It also presented resistance to fall and abrasion. Briquettes with higher bamboo residues content presented faster degradation, higher compressive strength, beyond higher volatile matters and calorific value.

Determinou-se a densidade básica, a massa específica aparente, a umidade de equilíbrio e a taxa de degradação térmica dos briquetes. Os briquetes foram avaliados por meio de testes de resistência à compressão e de tamboramento e o poder calorífico superior e inferior foram estimados a partir de equações ajustadas. Os briquetes produzidos com as maiores porcentagens de moinha de carvão vegetal apresentaram densidade básica, densidade aparente, teores de cinza e de carbono fixo mais elevados e menor friabilidade. Os briquetes com as maiores porcentagens de resíduos de bambu na composição apresentaram degradação térmica mais rápida, maior resistência à compressão, além de teor de materiais voláteis e poder calorífico mais elevados.Embrapa Florestas2014-09-24info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/mswordhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/61310.4336/2014.pfb.34.79.613Pesquisa Florestal Brasileira; v. 34 n. 79 (2014): jul./set.; 225-234Pesquisa Florestal Brasileira; Vol. 34 No. 79 (2014): jul./set.; 225-2341983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/613/374https://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/613/1161Dias Júnior, Ananias FranciscoAndrade, Azarias Machado deCosta Júnior, Djailson Silva dainfo:eu-repo/semantics/openAccess2017-04-28T12:48:44Zoai:pfb.cnpf.embrapa.br/pfb:article/613Revistahttps://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:2017-04-28T12:48:44Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
