60kW两段式秸秆气化炉运行特性

研究了上海交通大学热能研究所研制的60kW两段式秸秆气化炉的运行特性.以秸秆为原料在该气化炉上实验,考察原料量、空气过量系数对气化炉生产能力和碳转化率以及气化效率的影响,并分析了气化气成分及热值.数据表明该气化炉各项参数均优于一般固定床气化炉:原料消耗量为100kg/h,ER=0.35时,秸秆气化气平均热值为6599.6010/m~3,产气率为1.88m~3/kg,碳转化率为91.3%,气化效率为84.6%.

EXPERIMENTAL STUDY OF THE RUNNING CHARACTERISTICS ABOUT A 60kW TWO-STAGE STRAW GASIFIER

The mrming characteristics of a 60kW two-stage straw Gasifier developed by Shanghai Jiaotong University were studied. Simple treated rice straw was used as raw material. The influence of material quantity, equivalent ratio on gas yield rate, carbon conversion rate and gasification efficiency were detected. The product gas composition and its LHV are analyzed simultaneously. Results shown that this two-stage gasifier is better that other traditional fixed-bed gasifier: when fuel feed rate is 100kg/h and ER =0.35, the average product gas LHV is 6599.60kJ/m~3, gas yield rate is 1.88 m~3/kg, carbon conversion rate is 91.3%, gasification efficiency is 84.6%.
