Resumo: In the quest for recovery of waste generated from forest production to the process of industrial transformation of the biomass it was developed the process of briquetting. The cluster of wood particles facilitates the operations of handling of combustible material in addition to concentrating the available energy in terms of volume. The purpose of this study was to evaluate whether the raw material affects the quality of the briquette and verify the effect of pressure applied during the mechanical and energy  characteristics of the final product, and to evaluate the behavior of the material mix (MIX) compared to pure materials. The briquettes were produced in a pilot  briquetter, hydraulic piston, 120 °C with a constant pressure of 50 bar for eight minutes and 65, 95 or130 bar for two minutes. Six briquettes were used for each treatment. The characteristics evaluated were calorific value (GCV), bulk density and compressive strength. The raw material has a greater influence on the quality of briquettes than the compaction pressure. The low pressure is the most suitable for Pinus sp forest biomass briquettes. In this, MIX submitted satisfactory quality of briquettes with PCS 4,773 kcal kg-1, density 1220 kg m-³ and compressive strength of 167 kgf cm-2. doi: 10.4336/2010.pfb.30.62.101

A aglomeração de partículas de madeira facilita as operações de  manuseio do material combustível, além de concentrar a energia disponível em termos de volume. O objetivo do presente trabalho foi avaliar se a matéria-prima tem influência na qualidade do briquete e verificar o efeito da pressão aplicada durante o processo nas  características energéticas e mecânicas do produto final, além de avaliar o comportamento da  mistura de materiais (MIX) em relação aos materiais puros. Os briquetes foram produzidos em uma briquetadeira piloto, tipo pistão hidráulico, a 120 ºC com pressão constante de 50 bar por oito minutos e 65, 95 ou 130 bar por dois minutos. Foram utilizados seis briquetes para cada tratamento. As características avaliadas foram poder calorífico superior (PCS), densidade aparente e resistência à compressão. A matéria-prima tem maior influência na qualidade dos briquetes do que a pressão de compactação. A baixa pressão é a mais indicada para briquetes de biomassa florestal de Pinus sp. Nesta, o MIX apresentou qualidade satisfatória de briquetes com PCS de 4.773 kcal kg-1, densidade aparente de 1.220 kg m-³ e resistência à compressão de 167 kgf cm-2.doi: 10.4336/2010.pfb.30.62.101Embrapa Florestas2010-09-10info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/101Pesquisa Florestal Brasileira; v. 30 n. 62 (2010): abr./jun.; 101Pesquisa Florestal Brasileira; Vol. 30 No. 62 (2010): abr./jun.; 1011983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/101/116https://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/101/959Furtado, Thielly SchmidtValin, MarinaBrand, Martha AndreiaBellote, Antonio Francisco Juradoinfo:eu-repo/semantics/openAccess2017-04-28T13:14:16Zoai:pfb.cnpf.embrapa.br/pfb:article/101Revistahttps://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:2017-04-28T13:14:16Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
