| 摘 要： | 为了提高火电机组的热效率,建立了采用多级压缩、中间冷却以及多级膨胀、中间再热的燃气轮机与循环流化床（CFB）锅炉耦合系统性能的计算模型并进行了计算.结果表明：随着涡轮进口压力的升高和压气机级数的增加,耦合系统的热效率均有一个最大值;随着涡轮入口温度的升高和涡轮级数的增加,热效率可增加到约46%,因此,新系统具有高热效率、低厂用电率的优点;考虑到系统的结构复杂性以及综合经济性,压气机和涡轮均采用3级为宜. |

| Abstract: | In order to improve the efficiency of thermal power unit,a calculation model was established for the system coupling gas turbine and CFB boiler that applies multi-compression,inter-cooling,multi-expansion and inter-reheat technology,with which the system performance was calculated.Analysis results show that the thermal efficiency of the system will arrive at a maximum value with the rise of both the stage number of compressor and the inlet pressure of turbine.Meanwhile,the thermal efficiency rises all the t... |
