| This research aimed to evaluate briquettes made from coffee husk, eucalyptus sawdust and maize harvesting residues, and the influence of post compaction interval on some properties of the briquettes. After oven drying of the biomass, the briquettes were produced in a laboratory briquetting machine at 120 ºC and 15 MPa. Bulk density and heating value of the fresh biomass were analyzed. After compaction, influence of time on moisture content, volumetric expansion an bulk density of the briquettes was analyzed. From the results, it was observed that milled coffee husk had the highest mean value of bulk density. There was no statistical difference for higher heating value among the biomass analyzed. The effect of pos compaction interval was significant on... |

| This study aimed to produce and evaluating the briquettes made from residues of plant biomass and test different times and temperatures. The material utilized was composed of wood processing residues (wood shaving and sawdust), coffee bean parchment and coffee tree stem, beam stem and pod, soybean stem and pod, rice husk, corn leaf, stem, straw and cob and sugar cane straw and bagasse. Briquetting was performed at a pressure of 150 Bar. Different times were tested for briquetting sawdust from wood and different temperatures for rice husk and parchment coffee. For evaluation of the briquettes quality, the apparent relative density, compression resistance and combustion index were determined. The results indicated that the briquetting time and temperature... |
