Abstract

The system performance of the regenerative gas-turbine cycle with the steam injection into the combustor has been studied through the thermodynamic cyclic analysis. The effects of the pressure ratio, the steam injection ratio, the ambient temperature, and the turbine inlet temperature are investigated on the thermal efficiency, the fuel consumption, and the specific power as well as the operating conditions for the maximum thermal efficiency of the system. The results of the present analysis find that the use of steam injection in the regenerative gas-turbine system can greatly enhance the thermal efficiency and the specific power of the system.

증기분사 재생 가스터빈 시스템의 성능을 해석하고 최적 운전조건을 분석하였다. 해석모델을 통해 압력비, 증기분사율, 주위온도나 터빈입구온도 등의 설계변수들이 시스템의 열효율, 연료소모율, 비동력등 성능에 미치는 영향을 최적 운전조건에서 분석하였다. 해석결과들은 증기분사가 재생 가스터빈시스템의 열효율과 비동력을 대폭 향상시킬 수 있음을 보여주었다.
