Abstract:
In this study, the performance of hybrid biomass briquettes produced from carbonized sawdust and guinea corn straw using Cissus populnea as a natural binder was investigated. The briquettes were produced at varying blend ratios (S90G0B10, S75G15B10, S60G30B10, S45G45B10, S30G60B10, S15G75B10, S0G90B10). The produced briquettes were tested for ash content, volatile matter, carbon content, calorific value and performance indicators such as ignition time, burning time, burning rate and boiling time. The results showed that the ash content increased with higher proportions of guinea corn straw whereas the volatile matter decreased across the samples thereby influencing the ignition and combustion behaviour of the briquettes. The result of carbon content showed S45G45B10 composition reached a maximum value of 44.6%. This indicates an optimal balance in biomass blending. Similarly, the calorific value was peaked at 24.5 MJ/Kg for same composition demonstrating enhanced energy potential due to the interaction between the blending materials. The combustion performance analysis showed that briquettes with higher volatile matter ignited more easily when compared with those having higher carbon content. However, those with higher carbon content possessed more stable burning characteristics. The S45G45B10 sample showed superior overall performance (combining high energy output with efficient combustion and reduced boiling time). The study demonstrates the potential use of agricultural residues as sustainable energy sources and the effectiveness of Cissus populnea as an eco-friendly binder in briquette production.
