生物质气化-燃料电池/燃气轮机(biomass gasification fuel cell/gas turbine,BGFC/GT)发电系统在生物质能利用方面具有独特优势,近年来受到研究人员的重视。在对BGFC/GT发电系统基本原理及特点介绍的基础上,对其中2个重要研究内容,即部件技术手段、系统热力集成的研究现状进行了综述分析,指出发电系统的性能与组成系统的部件的技术手段密切相关,应针对所用生物质的特点及对产品气的要求对生物质处理技术进行选取;系统内部能量的有效利用是进行系统热力集成、提高热力学完善性的关键。目前BGFC/GT发电系统集成研究工作较少,应加强对系统内部可用能充分利用的研究,通过引入热力学系统分析方法提高系统内能量的有效利用,改善能量转化效率。
Great importance has been attached to the generating system of biomass gasification fuel cell/gas turbine (BGFC/GT) for its unique advantages in biomass utilization,.In addition to introducing the principles and characteristics of BGFC/GT generating system,the developments of technical means of components and thermal integration of the system have been analyzed.The results show that the generating system′s performance is closely related to the technical means of system components,and thus the correct biomass processing techniques should be chosen according to the characteristics of biomass and the requirements for product gas;the efficient utilization of the internal energy is the key to the system thermal integration and the thermodynamic perfection.Currently,there are few studies about the integration of BGFC / GT generating system.How to take full advantage of the system internal energy should be studied further,and the means of the introduction of a thermodynamic system analysis to improve the utilization of system internal energy and the energy conversion efficiency should be considered.
