| 摘 要： | 针对增压型熔融碳酸盐燃料电池/微型燃气轮机(MCFC/MGT)混合动力系统进行了系统设计、部分负荷特性和系统启动特性的分析.为实现系统的商业化,采用了基于现有微型燃气轮机进行系统设计的方法,对不同控制方式下系统的部分负荷运行特性进行了比较,提出了系统启动方案并对启动过程中可能出现的问题及系统特性进行了分析.结果表明,基于燃气轮机所设计系统性能要比基于MCFC的性能稍差,在系统部分负荷运行时保持MCFC的工作温度有助于系统性能的改善,由于MCFC自身的特点这种系统不适合频繁的启动.

| Abstract: | Abstract： This paper addressed the design, off design and startup analysis of a hybrid system based on the coupling of a micro gas turbine and pressured molten carbonate fuel cell. The design of hybrid system was based on a commercially available micro gas turbine for the commercialization. The part load performances were compared considering different control methods. The system startup method was proposed and the possible problems and system performances for the startup process were studied. The results show that the performance is poorer for the system designed based on MGT than MCFC. The system performances can be improved by keeping the operating temperature as high as possible for the part load operation. This system is not suitable for frequent startup considering the characteristics of MCFC. |
