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 02 under oxygen volume fraction of 425% 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 425%, the volume fraction of combustible components was increasing quickly. Compared to air gasification, the gasification efficiency with oxygen-rich air was improved significantly．
