ABSTRACT
A method for power plant Gas Turbine (industrial) overall performance evaluation was developed based on the thermodynamic cycle. Some key parameters affecting the simple cycle efficiency and power of the GT, such as compressor pressure ratio, turbine inlet temperature, compressor efficiency, compressor exit diffuser Cp, combustor pressure loss, turbine efficiency, OTDF, RTDF, blade metal allowable temperature and turbine exit diffuser Cp has been studied across a wide range of possible operating conditions. The effects on simple cycle of GT efficiency, GT specific power and turbine exit temperature of these parameters were discussed, these parameters should be carefully considered in a new GT design.
摘要：本文针对燃机热力学循环系统，发展了理论分析的燃机性能评估计算方法。基于该方法，在可能的比较广泛的运行条件下详细地分析了压气机压比、透平入口温度、压气机效率、压气机排气扩压器 Cp、燃烧器压损、透平效率、OTDF、RTDF、叶片金属温度及透平排气缸 Cp等关键因素，讨论了其对燃机性能、燃机出力及透平出口温度的的影响规律，在燃机总体性能参数选取时应该特别予以重视。
