Evaluation of briquettes from bamboo species produced under different temperature

Resumo

The present study aims to evaluate the quality of briquettes produced from the biomass of bamboo species under different briquetting temperature conditions. The species selected were Dendrocalamus asper, Bambusa vulgaris, Bambusa tuldoides and, for comparative purposes, a hybrid of Eucalyptus urophylla x Eucalyptus grandis, which were cut and transformed in sawdust to produce briquettes at three temperatures: room temperature ±30ºC, 80ºC, 120ºC. Biomass and briquettes characteristics were assessed. The species used for production of briquettes did not influence the highest calorific value, the bulk and energetic densities. Bamboo briquettes showed lower volumetric expansion values and higher values of tensile strength by diametral compression and durability when compared to eucalyptus, indicating their potential for energy use in the form of densified materials. The use of temperature on bamboo and eucalyptus biomass compacting improved the physical and mechanical properties of the briquettes.
