Effects of densification parameters on the quality of briquettes produced from mixing miscanthus giganteus and agricultural residues

Abstract

The aim of this study was to investigate the influence of densification parameters on the compaction degree of briquettes obtained from biomass derived from mixtures of Miscanthus giganteus and arboricultural residues. The study focuses on establishing the relationships between the influence of process variables (matrix temperature, compaction pressure and biomass moisture) on briquette particle density. The experiments were carried out in the UTM Scientific Laboratory of Solid Biofuels, using a laboratory equipment developed by the authors of this study, which allows the compaction of single briquettes in closed cavity and in flow by monitoring the compaction regimes. The study was conducted using a 2k complex central factorial experiment, to which 2k "star" points were added at a distance α=5%, along with 2 experiments conducted at the central point
