摘要
环境压力吸热燃气轮机循环(APGC)能够吸收发电装置排出的低压废气能量,增加系统本身的做功能力和效率,达到节能、减少燃料消耗的目的。本文基于Aspen Plus软件建立了APGC以及与回热Brayton循环组成的复合循环模型,给出了APGC的结构示意图,模拟和分析了回热Brayton循环(BC)和APGC组成的复合系统性能。通过对回热复合循环性能的分析得出,系统最佳性能可以通过改变底部循环膨胀压力和顶层循环压比获得,并提出加权分析方法,具有一定的理论设计和实践应用的指导意义。
The hybrid system of Brayton cycle and ambient pressure gas turbine cycle （APGC） was described and the results of performance study was presented. The performance of the system was calculated by using the commercial process simulation package Aspen Plus. The results revealed that the optimum performance of the hybrid system could be obtained by changing upper cycle pressure ratio and bottom cycle expansion pressure. The expert factor analytic method, which is significant in theoretical design and practical application of a new proposed cycle, was also presented to provide the design pressure ratio of the combined cycle according to the usage of system.
