摘要
以固定床气化炉为反应器、秸秆成型燃料为原料、纯氧为气化介质，通过改变进氧气量来调节气化当量比，试验研究高当量比（0．31—0．40）对气化结果的影响。发现随着当量比的增加，气化反应温度逐渐升高、碳转化率和气体产率逐渐增加、产出气热值逐渐降低、产出气中焦油含量逐渐降低。试验结果表明：高当量比生物质氧气气化的方法可行；通过增大当量比的方法提高反应温度，可有效降低产出气中的焦油含量。
Straw densification briquetting fuel gasification under oxygen was carried out in a downdraft gasifier. The effects of high equivalence ratio （0.31-0.40） on results of gasification are investigated through a series of experi- ments, which change equivalence ratio via adjusting the feeding rate of oxygen. With the increasing of equivalence ratio, it is found that reaction temperature, carbon conversion and gas productivity are all increased but low heating value and tar content. The experimental results showed that the way of high equivalence ratio biomss oxygen gasifi- cation is feasible and the method of increasing equivalence ratio to raise reaction temperature can reduce the tar content significantly in producer gas.
