提出了一种由流化床热解器和输送流化床气化器组成的流化床两段气化工艺，用于气化生物质生产低焦油含量的燃料气。在前期基础研究的基础上，设计并建造了一台处理量为600 kg/h的中草药渣自热式两段气化炉。工业示范装置运行稳定阶段的测试数据表明，当热解炉和气化炉的反应温度分别保持在700 ℃和850 ℃左右时，燃气热值可达1200 kcal/Nm 3，所产燃气中焦油含量约为0.4 g/Nm（3）。该中试工业示范装置的结果充分验证了所提出的流化床两段气化工艺的可行性和技术特点。(C)2016由Elsevier Ltd.出版
A fluidized bed two-stage gasification process, consisting of a fluidized-bed (FB) pyrolyzer and a transport fluidized bed (TFB) gasifier, has been proposed to gasify biomass for fuel gas production with low tar content. On the basis of our previous fundamental study, an autothermal two-stage gasifier has been designed and built for gasify a kind of Chinese herb residue with a treating capacity of 600 kg/h. The testing data in the operational stable stage of the industrial demonstration plant showed that when keeping the reaction temperatures of pyrolyzer and gasifier respectively at about 700 degrees C and 850 degrees C, the heating value of fuel gas can reach 1200 kcal/Nm3, and the tar content in the produced fuel gas was about 0.4 g/Nm(3). The results from this pilot industrial demonstration plant fully verified the feasibility and technical features of the proposed FB two-stage gasification process. (C) 2016 Published by Elsevier Ltd.
