Utilização de resíduos do processamento de teca (Tectona grandis L.f.) na produção de briquetes

Abstract

Briquetting is an effective way to utilize the biomass residues for energy purposes. The objectives of this research were to characterize the briquettes produced from the waste processing of young teak (Tectona grandis L.f.). The properties analyzed in briquettes were density, calorific value, ash content, extractive content and dimensional expansion. It was used a factorial experiment composed of two types of waste of young teak (sawdust and bark) and three moisture levels (10%, 12%, 15%). The found results showed that the use of the residues of Tectona grandis L.f. it is viable for the briquettes production; the ideal moisture found for the production of the briquettes was 10%; the analyzed properties aim that the produced briquettes is compatible patterns for domestic and commercial use, due to great amount of ashes the use of the briquettes is not indicated for metallurgy; the produced briquettes showed resistant and stable, therefore is worth to consider the development of new researches that develop processes that generate smaller amount of ashes so that it becomes also viable the use of these residues in the metallurgical industry.
