In the present work, selected agroindustrial solid residues from Brazil - biosolids from meat processing wastewater treatment and mixture of sawdust with these biosolids; residues from apple and orange juice industries; sugarcane bagasse; açaí kernels (Euterpe oleracea) and rice husk - were characterised as solid fuels and an evaluation of their properties, including proximate and ultimate composition, energy content, thermal behaviour, composition and fusibility of the ashes was performed. The lower heating value of the biomasses ranged from 14.31 MJkg(-1) to 29.14 MJkg(-1), on a dry and ash free basis (daf), all presenting high volatile matter content, varying between 70.57 wt.% and 85.36 wt.% (daf) what improves the thermochemical conversion of the solids. The fouling and slagging tendency of the ashes was predicted based on the fuel ash composition and on the ash fusibility correlations proposed in the literature, which is important to the project and operation of biomass conversion systems. The potential for application of the Brazilian agroindustrial solid residues studied as alternative energy sources in thermochemical processes has been identified, especially concerning direct combustion for steam generation.
在本工作中，选择了巴西的农业工业固体残留物 - 肉类加工废水处理的生物固体和这些生物固体与木屑的混合物；苹果和橙汁工业的残渣；甘蔗渣；巴西莓（Euterpe oleracea）核和稻壳 - 作为固体燃料，并对其性质进行了评估，包括近似和最终组成、能量含量、热行为、灰分的组成和熔融性。生物质的低位发热量在干燥无灰基础（daf）上为 14.31-29.14MJkg(-1)，所有生物质都具有高挥发物含量，在 70.57wt.%到 85.36wt.%（daf）之间变化，这提高了固体的热化学转化。根据燃料灰分的组成和文献中提出的灰分熔融性相关性，预测了灰分的结垢和结渣倾向，这对于生物质转化系统的项目和运行非常重要。已经确定了所研究的巴西农业工业固体残留物作为热化学过程中替代能源的应用潜力，特别是在直接燃烧以产生蒸汽方面。
