Gas turbine intake air hybrid cooling systems and their rational designing

The general trend to improve the fuel efficiency of gas turbines (GT) at increased ambient temperatures is turbine intake air cooling (TIAC) by exhaust heat recovery chillers high absorption lithium-bromide (ACh) a simple cycle are most widely used, but they not able cool lower than 15°C because chilled water temperature about 7°C. A two-stage hybrid absorption-ejector (AECh) were developed with ejector chiller as low stage provide deep 10°C and lower. novel in TIAC type has been proposed 50% higher annual saving temperate climatic conditions compared ACh cooling. advanced methodology design rational distribute capacity systems that provides closed maximum reduction without oversizing was developed.
