Resumo: | Biomass is a renewable energy source most used in the world, however, depending on the chemical properties and origin of the material used as biofuel, the amount of ash generated during combustion can be high, harming the energetic harnessing. The objective of this study was to characterize chemically and physically biomass: bark, sawdust, and urban pruning; used for energy generation. Also, part of the study was the physical characterization of briquettes produced from these materials. The analyzes performed to characterize the biomass were: moisture determination, higher heating value, proximate analysis and chemical composition - extractives, lignin and holocellulose contents. Subsequently, the biomass was briquetted and the mechanical properties of the briquettes were tested. The results showed that all biomass (bark, sawdust, and urban pruning) has the energy potential to be used in the industry. T1 briquettes (100% bark) showed the highest mechanical resistance. However, the formation of blends should be sought to minimize the ash content in the boiler. Thus, blends T2 and T3 can be considered as the best alternatives for the company. |
