상압형 MCFC/가스터빈 하이브리드 시스템의 구성방법에 따른 설계성능 분석

Effect of System Configuration on Design Performance of Atmospheric Pressure MCFC/Gas Turbine Hybrid Systems

  • 발행 : 2004.11.01

초록

Design performances of various configurations of hybrid systems combining an atmospheric pressure molten carbonate fuel cell and a gas turbine have been analyzed. Two different fuel reforming methods (internal and external reforming) were considered. Influences of turbine inflow heating method, location of fuel combustor and associated component arrangements were investigated. In general, internal reforming leads to higher system efficiencies. The optimum design pressure ratio varies among different system configurations. In particular, the design point selection is closely related to the allowable turbine inlet temperature. Configurations with direct heating of turbine inlet flow may realize both higher efficiency and higher specific power than those with indirect heating.
