Tóm tắt

This study investigates the impact of supplementing 20% oxygen into the air supply during the gasification of a 65% RDF and 35% rice husk blend in a small-scale downdraft gasifier. The results demonstrate that oxygen enrichment significantly elevates combustion zone temperatures and reduces nitrogen dilution, leading to a substantial increase in combustible gas components. Specifically, comparative data reveal that at an Air Ratio (ER) of 0.3, CO concentration rises markedly from 23% to 44%, resulting in a total combustible fraction of approximately 70%. Similarly, at ER 0.4, CO levels increase from 20% to 34%, while at ER 0.5, they rise from 12% to 30%. These findings confirm that oxygen enrichment effectively enhances the heating value and quality of biomass-derived syngas.
