摘　　要：为了提高生物质的气化效率,掺杂煤作为惰性粒子,在流化床上进行了不同温度和生物质与煤不同质量比的气化试验,得出了各工况下气体产率及气化特性,分析了温度和质量比对二者的影响。结果表明:当气化温度在800～900℃之间时,温度提高,气化效率增加;当生物质与煤质量比为3∶1时,气化效率最佳。In order to improve the efficiency of biomass gasification, we take coal as inert particles. We carry out the experiment with different temperatures and different mass ratio of coal and biomass in a fluidized bed. Through the experiment, We obtaine the gas production rate and gasification characteristics in some conditions. Then analysis of the effects causing by the different temperatures and mass ratio. The results show that： when the temperature is between 800 - 900 ℃as the temperature increased, the gasification efficiency increases; when the mass ratio is 3 ： 1, the gasification efficiency is the best.
