摘要：

为了研究不同操作工艺参数对垃圾衍生燃料（RDF）流化床富氧气化特性的影响,在常压流化床气化炉上进行徐州RDF的富氧气化实验,研究气化温度、当量比及氧体积分数对气化特性的影响.结果表明：随着气化温度由600 ℃升至800 ℃,气体产物中H2和CO体积分数显著增加,气体热值和气化效率增加；当量比通过影响气化反应程度及燃料碳转化率间接改变气化效果,当氧体积分数为425%、气化温度为770 ℃时,气化最佳当量比约为02,过高或过低均会导致可燃组分和气化效率的降低；随着氧体积分数由21%增至425%,可燃组分体积分数不断增加,与空气气化相比,富氧气化的气化效果有显著改善.

Abstract:

XuZhou’s refuse derived fuel (RDF) gasification with oxygen-rich air was conducted in a fluidized bed gasifier in order to analyze the influence of different operating parameters on the gasification characteristics. The effects of equivalence ratio, gasification temperature and volume fraction of oxygen on performance of product gases were investigated through a series of experiments. Results showed that rising temperature from 600 ℃ to 800 ℃ enhanced the volume fraction of H2 and CO and improved low heating value (LHV) and gasification efficiency. Equivalence ratio by influencing the gasification reaction degree and the carbon conversion rate indirectly changed the gasification effect. The optimum equivalence ratio for oxygen-rich air gasification was about 02 under oxygen volume fraction of 425% and 770 ℃. Higher or lower equivalence ratio can reduce the combustible components and gasification efficiency. As volume fraction of oxygen was increased from 21% to 425%, the volume fraction of combustible components was increasing quickly. Compared to air gasification, the gasification efficiency with oxygen-rich air was improved significantly．
