摘要:
为研究生物质热解发电技术,该文利用ASPEN PLUS化工通用模拟软件建立等离子喷动-流化床热解生物质及合成气发电的模型。针对生物质在等离子体喷动-流化床中的氧气气化过程,模拟计算热解合成气的气体组分。以M701F型燃气轮机为模拟对象,模拟合成气发电系统并进行结果分析。分别对气化温度为400 ℃、500 ℃、600 ℃、700 ℃、800 ℃的气化系统和发电系统进行热力学分析,并计算其能量、、能量效率、效率及综合效率。研究发现,在气化剂温度从400℃上升至800 ℃的过程中,气化系统的效率为59%~60%,能量效率为57%~61%,气化系统的效率普遍低于相应的能量效率。合成气发电系统的发电效率为26%~28%,高于传统热解燃气的发电效率。
Abstract:
The biomass pyrolysis of a plasma spray-fluidized bed and the synthesis gas electricity generation model is established using ASPEN PLUS chemical general simulation software to research biomass pyrolysis and electricity generation technology.The composition of the pyrolysis synthesis gas is simulated for the oxygen gasification process of the biomass in the plasma spouted-fluidized bed.A synthesis gas electricity generation system is simulated using a M701F gas turbine as the simulation object.The energy values,exergy values,energy efficiency,exergy efficiency and combined efficiency of the gasification system and electricity generation system with gasification temperature of 400 ℃,500 ℃,600 ℃,700 ℃ and 800 ℃ are calculated.The results show that when the temperature of gasification agent improves from 400℃ to 800℃,the efficiency of the gasification system is 59%~60% and the energy efficiency is 57%~61%,and the exergy efficiency of the gasification system is generally lower than the corresponding energy efficiency.The power generation exergy efficiency of the synthesis gas electricity generation system is 26%~28% and higher than that of traditional pyrolysis gas.
