摘    要:采用新型床料在鼓泡流化床中进行了2种典型的木本和草本生物质与烟煤的空气-水蒸气气化试验,研究了生物质掺混比例对燃气组分和热值、气化效率及碳转化率等参数的影响规律.结果表明:当松木屑的掺混比例从0%增大到100%时,H2和CO的体积含量分别增加了4.6%和4.4%,CO2的体积含量减少了3%,CH4和CnHm的含量也有所增加;当稻秸的掺混比例从0%增大到100%时,CO的体积含量先从25.8%上升至27.5%,再下降至25.3%,其他燃气组分的变化趋势与松木屑和煤气化的相类似;随着生物质掺混比例的增加,2种生物质和煤共气化的气化效率和碳转化率均有所提高,且在共气化过程中存在协同效应.

Abstract:In order to study the influence of blending ratios on gas component and LHV,gasification efficiency and carbon conversion rate during co-gasification of biomass(pine sawdust or rice straw) and coal in a bubbling fluidized bed,experimental tests were carried out with air and steam.Results show that when the blending ratio of pine sawdust rises from 0% to 100%,the volume concentration of H_2 and CO will respectively increase by 4.6% and 4.4%,CO_2 reduce by 3%, and CH_4 and C_nH_m will both increase slightly;w...
Keywords:co-gasification  fluidized bed  pine sawdust  rice straw  bituminous  air-steam  blending ratio
