中文摘要：
生物质与煤共气化可解决生物质不易稳定流化及气化气焦油含量高的问题。基于流化床反应器的松木屑与褐煤共气化试验，研究松木屑掺混比例对合成气及未反应碳的[火用]值和[火用]效率的影响，并将试验值和理论值进行分析比较。结果表明，各成分气体对合成气[火用]值的贡献关系是：CH4〉C2H4〉CO〉H2，松木屑气化有更好的能量利用效率；合成气[火用]值和[火用]效率的试验值均高于计算值，而未反应碳[火用]值和[火用]效率的试验值均低于计算值；在生物质掺混比例为50％的工况下，松木屑与褐煤共气化协同作用最显著，表现为一种更好的气化方式。
英文摘要：
Co-gasification of biomass and coal can improve the fluidization of biomass and prohibit the production of tar. The effect of pine sawdust blending ratio on exergy value, studied based on the experiment of pine sawdust and lignite exergy efficiency of product gas and unreacted carbon was co-gasification process in a fluidized bed gasifier. And the test values were compared with the calculated values. The results show that the contribution of gas component to exergy value is as follows： CH4〉C2H4〉CO〉H2; Pine sawdust gasification has better energy efficiency than lignite gasification. The test values of exergy value and exergy efficiency of product gas are higher than the calculated values, nevertheless, the test values of exergy value and exergy efficiency of unreacted carbon are lower than the calculated values. And when the blending ratio of pine sawdust is 50%, the synergistic effect is obvious, thereby co-gasification of biomass and lignite shows a better gasification technology.
