首次提出了一种新型的混合式太阳能预热中冷燃气轮机(SPIcGT),其利用线性菲涅耳太阳镜场在进入燃烧室前对压缩空气进行预热.本文以太阳能预热燃气轮机(SPGT)作为参考,采用了八个绩效指标在广州(中国)的天气数据下进行分析.结果表明,SPIcGT系统的燃油效率提高了19.5％,而SPGT系统的效率仅提高了0.26％,因此SPIcGT系统优于SPGT系统,且与SPGT的10358 kJ/kWh相比,SPIcGT有着更低的比油耗(约7017 kJ/kWh).同时,线性菲涅耳太阳镜场与中冷燃气轮机循环的太阳能集成比与常规燃气轮机循环的太阳能集成更经济,其电价为4.34 US/kWh,比SPGT降低了5.15％.此外,线性菲涅耳太阳镜场与中冷燃气轮机的结合可以大大降低燃油消耗和CO2排放(约19.3％).“,”In this study, a new hybrid Solar Preheating Intercooled Gas Turbine ( SPIcGT) is originally introduced, in which a linear Fresnel solar field used for preheating the compressed air before entering the combustor. The solar Preheating Gas Turbine ( SPGT) has been used as a reference gas turbine cycle. Eight performance indicators have been used in the analysis under Guangzhou ( China) weather data. The study reveals that the SPIcGT is superior to the SPGT system as it is capable of boosting the fuel-based efficiency by 19. 5％ versus 0. 26％ for the SPGT system. The SPIcGT has lower specific fuel consumption (about 7017 kJ/kWh) compared with the 10358 kJ/kWh for SPGT. Meanwhile,the solar integration of the linear Fresnel solar field into an intercooled gas turbine cycle is more economical than the solar integration with the conventional gas turbine cycle. The levelized electricity cost of 4. 34 USC//kWh was achieved for SPIcGT which is lower than 5. 15％ for SPGT. Moreover,the fuel consumption and CO2 emissions can be reduced greatly (about 19. 3 ％) by integrating the linear Fresnel solar field with the intercooled gas turbine.
