Combustion stands as one of the essential methods in resource recovery for disposal of distillery sludge. In this study, sludge along with coal has been considered an option for co-combustion in the grate furnace aiming for further application as a boiler fuel. Detailed analysis was carried out to verify the feasibility of co-combustion of sludge with coal. Distillery sludge was blended with coal as a mixed fuel at co-combustion ratios of 20%, 30%, and 40% in grate furnace. The results of the analysis indicated that the combustion with 40% sludge mixed coal is suitable for application as a fuel in boiler. According to the chemical composition of bottom ash, weight loss from 460 to 800°C indicated the presence of C-C and C-H. Also, EDX and XRD analyses of mixed fuel was carried out to determine the mineralogical composition. The presence of quartz (SiO), mullite (3AlO2SiO), and hematite (FeO) present in the ash can be used as mineral additives in cement industries. The study also provided a promising approach towards diverting combustion bottom ash from landfills for its utilization in various industries which can be a possible cost-effective solution.
燃烧是资源回收中处理酿酒厂污泥的一种重要方法。在这项研究中，将污泥与煤一起作为炉排炉共燃的选择，旨在进一步用作锅炉燃料。进行了详细的分析以验证污泥与煤共燃的可行性。将酿酒厂污泥与煤以 20%、30%和 40%的共燃比例混合作为混合燃料在炉排炉中进行共燃。分析结果表明，40%污泥混合煤的燃烧适合用作锅炉燃料。根据底灰的化学成分，460 至 800°C 之间的重量损失表明存在 C-C 和 C-H。此外，还对混合燃料进行了 EDX 和 XRD 分析，以确定其矿物成分。灰分中存在的石英（SiO）、莫来石（3AlO2SiO）和赤铁矿（FeO）可用作水泥工业中的矿物添加剂。该研究还提供了一种有前途的方法，可以将燃烧底灰从垃圾填埋场转移到各个行业中进行利用，这可能是一种具有成本效益的解决方案。
