生物质中水分对共气化化学链发电系统的影响研究
Effect of Blending Ratio on Co-Gasification Chemical Looping Power Generation System
摘要: 生物质与煤的共气化发电技术是一项具有发展前景的技术，能够有效降低化石燃料对环境的污染。本研究运用Aspen Plus软件对生物质与煤共气化化学链联合循环发电系统进行模拟，探究生物质中水分对共气化发电系统的影响。研究结果表明，当芦竹质量掺杂比例一定时，降低芦竹水分含量会减少燃料反应器出口烟气流量，提高NiO转化率和干燥器的热负荷。并且，水分含量的降低能够有效的提高共气化发电系统的净发电效率。当芦竹质量掺杂比例为10%且水分为0%时，系统净发电效率高达42.35%。
Abstract: The co-gasification power generation technology of biomass and coal is a promising technique that can effectively reduce the environmental pollution caused by fossil fuels. This study employs Aspen Plus software to simulate a biomass and coal co-gasification chemical looping combined (CLC) cycle power generation system, investigating the impact of moisture in biomass on the co-gasification power generation system. The research findings indicate that, when the mass blending ratio of Arundo donax is constant, reducing its moisture content can decrease the flue gas flow rate at the fuel reactor outlet, enhance the conversion rate of NiO, and increase the thermal load of the dryer. Moreover, the reduction in moisture content can effectively boost the net power generation efficiency of the co-gasification power generation system. When the mass blending ratio of Arundo donax is 10% and its moisture content is 0%, the system’s net power generation efficiency can reach as high as 42.35%.
