APGC燃机与燃料电池复合发电系统性能分析

Performance analysis of APGC gas turbine and SOFC hybrid power system

基于新型环境压力下吸热燃气轮机循环APGC(ambient pressure gas turbine cycle),提出了APGC燃气轮机和常压固体氧化物燃料电池(SOFC)组成的复合发电系统.利用商业软件Aspen plus,建立了APGC燃气动力装置以及常压SOFC的数值分析模型.以西门子公司生产的120 kW燃料电池结构及设计参数作为分析基础,探索了APGC燃气轮机和SOFC组成的常压SOFC/APGC复合发电系统的性能.研究结果表明:复合装置的发电效率可以达到66.5%,显示出复合发电性能的优势.

Based on the study of the new ambient pressure gas turbine cycle （APGC）, the APGC gas turbine and ambient pressure solid oxide fuel cell （SOFC） hybrid power system is presented . The detailed analytic models are established by the commercial software Aspen plus for the performance analysis of the SOFC/APGC hybrid power system. The performance analysis is conducted according to the structure and parameters of 120 kW SOFC designed by Siemens and shows that the generating efficiency in the hybrid power system can reach 66.5%. This SOFC/APGC hybrid power system is advantageous to generating electric power.
