Mechanical properties enable to handle storage and transport of fuel briquette. Binder is key element of these mechanical properties. Biobinder is more and more used to avoid pollution and improve heating value. The goal of this study is to determine the best mixture from corn cobs, cassava and plantain peels using simplex centroid mixture design. The result reveals that the proportion of cassava peels influences positively the strength, negatively the low heating value (LHV) and the degradation rate of briquette (DRB). The proportion of plantain peels has negligible effect on the strength and the LHV and influences slightly the DRB. The proportion of corn cobs influences positively the LHV, the DRB and the strength. The superposition of the iso responses curves shows that the 20, 20, 60 for defined as the best mixture. The index resistance impact (IRI) of 1000 illustrates that the briquettes obtained from the best mixture can be handled without breaking. Values of 35% for thermal efficiency and 3.5 KW for fire power reveal that these briquettes are suitable for domestic and industrial application.

机械性能能够处理燃料块的储存和运输。粘合剂是这些机械性能的关键元素。生物粘合剂越来越多地用于避免污染和提高热值。本研究的目标是使用单纯形质心混合设计确定玉米芯、木薯和车前草皮的最佳混合。结果表明，木薯皮的比例对强度有正面影响，对低热值（LHV）和煤球的降解率（DRB）有负面影响。车前草皮的比例对强度和 LHV 的影响可以忽略不计，对 DRB 的影响很小。玉米芯的比例对 LHV、DRB 和强度有积极影响。iso 响应曲线的叠加表明，20、20、60 被定义为最佳混合物。1000 的指数抗冲击强度 (IRI) 说明从最佳混合物获得的煤球可以在不破裂的情况下进行处理。35% 的热效率和 3.5 KW 的火力值表明这些煤球适用于家庭和工业应用。
