| 摘 要： | 针对下吸式生物质固定床气化炉,采取主动配气的方式,进行焦油的热裂解性能试验.试验结果表明:主动配气下,气化炉同一截面反应均匀,具有较厚的高温层,为焦油热裂解提供良好的条件,并寻找到气化反应的最优配气量,在此配气量下,以玉米秸秆为原料,燃气中的焦油质量浓度约为600 mg/m3,热值达到5 400 kJ/m3左右,同时验证了灰层厚度等其他因素对焦油热裂解和燃气质量的影响.

| Abstract: | Active air distribution way was taken to the experimentally study on the tar cracking property in downdraft fixed-bed biomass gasifier.The results showed that the reaction was uniform in the same section and the gasifier had a thicker layer at high temperature under the active air distribution,which provided good conditions for tar cracking.The optimum air distribution way was achieved by the experiments,and the tar content in gas was about 600mg/m3 in the range using corn stalk as the material with high he... |
