Avaliação da qualidade de briquetes de Cafulo de Coco pré-carbonizado como alternativa energética sustentável

Abstract

With the aim of helping to reduce the problem of deforestation in the country associated with the consumption of biomass for energy purposes in the agricultural community of Cumbane in the agricultural community in the province of Inhambane, this study was carried out with the aim of to determine the quality parameters of the briquettes produced from waste from coconut biomass that used to be underutilised. The properties properties analysed were: immediate analysis, upper and lower calorific value, apparent, energy and bulk densities, abrasion resistance, water boiling test and combustion index. combustion index. The briquette mixtures tested consisted of: mixture A: coconut charcoal+clay+water; mixture B: coconut charcoal+bovine manure+water and mixture C: coconut charcoal+clay+bovine manure+water. The data was analysed analysed and the means compared using the Tukey test at 5% significance. test. The results of the study suggest that mixture B had the best results. However, none of the varieties performed well in the abrasion resistance test. abrasion resistance test. The combustion index test and the water boiling test showed that the briquette performed well in relation to the literature literature. Research into other forms of manual compaction is recommended in order to in order to increase the apparent density of the briquette, which in turn will improve its physical and energy characteristics.
