摘  要：
使用不同含水率的木粉为原料,以180~270 kg/h的进料速度在内径0.5 m、高9 m的常压流化床气化炉上进行了富氧-水蒸气气化制备合成气实验。考察了当量比、水蒸气配比、二次风以及原料含水率对气化温度、燃气组分、低位热值、气体产率、气化效率和碳转化率等参数的影响。结果显示:当量比为0.25~0.27之间,水蒸气配比0.4时,H2含量最高可达28.7%,H2/CO为0.94,燃气热值9.9 MJ/m3,气化效率大于75%,碳转化率大于97%;提高二次风比率可明显降低焦油含量,在总当量比0.29、二次风比率25%时焦油含量为49 mg/m3;原料水分增加,气体质量下降,含水率以不超过20%为宜。

摘  要：
Biomass gasification with steam-oxygen enriched air in an atmospheric fluidized bed gasifier was studied.The gasifier was 9m high with the bed diameter of 0.5m.Sawdust with different moisture contents was used as feedstock,and it was fed into the gasifier at flow rates of 180～270kg/h.The effects of equivalence ratio,steam to biomass ratio,secondary flow ratio and feedstock moisture on the bed temperature,gas compositions,tar content,lower heating values,gas yield,carbon conversion efficiency and cold gas efficiency were investigated.The results showed under the operating conditions of ER is 0.25～0.27 and S/B=0.4,the following syngas was obtained: H2 content of 28.7%,H2/CO ratio of 0.94,low heating value of 9.9MJ/m3,cold gas efficiency was more than 75%,carbon conversion efficiency was more than 97%;a second flow ratio of 25% at the ER of 0.29 can significantly reduce the tar content to 49mg/m3,but hardly improve the quality of the gas produced;the rise of the feedstock moisture content caused a significant increase in CO2 content and a reduction in H2 and CO contents,and the moisture content is expected not to exceed 20%.
