中文摘要:
      建立了基于航空煤油重整固体氧化物燃料电池-涡轮发动机(SOFC-GT)混合动力系统仿真模型,比较了两种回热方式的重整装置以及不同涡轮布置位置时的系统性能变化,优选出最佳的混合动力系统架构。进一步分析了压气机压比、燃料利用率、燃油流量以及空气流量等运行参数对SOFC-GT混合动力系统性能的影响。研究结果表明:设计点工况下,最佳混合动力系统的发电效率能达到45%,体现出良好的系统性能;当燃料利用率为082时混合动力系统的效率和功率最高;随着燃油流量(0051 1~0058 4 mol/s)的增加,混合动力系统的效率和功率均增加;而随着压气机压比(25~33)或者空气流量(37~44 mol/s)的增加,混合动力系统的效率和功率都减小。
英文摘要:
      A simulation model of the solid oxide fuel cell-gas turbine (SOFC-GT) hybrid system on the basis of the aviation kerosene reforming was established. The effect of two heat recovery methods on the reformers and the effect of the turbine positions on the system efficiency were studied to obtain the optimal system architecture. The performance of the SOFC-GT hybrid system was evaluated by studying the effects of the compressor pressure ratio, fuel utilization ratio, fuel flow rate and air flow rate. Results showed that the efficiency of the best hybrid system can reach 45% at the design condition, and the system demonstrated excellent performance. The efficiency and power of the system reached the peak with the fuel utilization ratio equaling to 082. Moreover, the efficiency and power could be improved with the growing fuel flow rate (from 0051 1 mol/s to 0058 4 mol/s), while the increasing compressor pressure ratio (from 25 to 33) or air flow rate (from 37 mol/s to 44 mol/s) could result in the reduction of the efficiency and power.
