摘　　要：利用流化床气化炉进行甘蔗渣与煤混合原料的气化,以水蒸气和空气为气化剂,进行连续气化生产低热值混合燃气。试验过程中,通过改变气化温度、S/B(水蒸气/生物质)、空气当量比3个试验操作参数,记录不同工况下的生成燃气组分以及燃气热值,寻求甘蔗渣与煤共气化试验中的最佳操作工况。得出试验最佳工况为:气化温度为950℃左右,S/B值为0.25,空气当量比为0.24,生物质与煤的混合比例为4∶1。在此工况下进行气化试验,制得燃气最为纯净、气体热值最高,为6.9 MJ/m^3左右。Experiment of co-gasification of sugarcane bagasse and coal in a fluidized bed gasifier was processed,with water vapor and air as gasification agent,and continuous gasification to producte gas was conducted. With the change of temperature,S / B and ER,gas component and its calorific value were changed,and the gas component and its calorific value when the working condition changed were recorded in the experimental process. And we got the best working condition： when that the temperaturee is 950 ℃,S / B is equal to 0. 25,and the ratio of biomass and coal is 4∶ 1,the gas is the best,and the calorific value is the higest,which is about 6. 9 MJ / m^3.
