摘　　要：使用HSC Chemistry软件计算不同温度和水蒸气质量比下气化产物的分布规律,通过对反应条件进行优化,得出最佳气化温度为1050 K。在优化反应条件下制备的气化产物驱动的新型发电系统发电效率可达53.73%~54.73%,电能增益系数能达到1.98~2.48,优于物料直燃发电(效率约为35%,电能增益系数为1)。新型发电系统的CO2单位排放量只有0.47~0.48 kg/kWh,相比直燃发电CO2排放量减少51%~61%,具有巨大的CO2减排效益。The distribution of gasification products at different temperature and water vapor mass ratio is calculated with HSC Chemistry software,and the optimal gasification temperature of 1050 K is determined.The efficiency of electricity generation system driven by gasification product obtained from optimal condition is determined between 53.73%and 54.73%.At the same time,the electricity gain factor ranges from 1.98 to 2.48.It is better than the direct burning system driven by carbonaceous materials with efficiency of 35%and electricity gain factor of 1.The CO2 emission of novel system is 0.47-0.48 kg/kWh and 51%-61%less than that of the direct burning system,which results significant reduction benefits of CO2 emission.
