碩士 === 國立成功大學 === 化學工程學系 === 102 === This research combined SOFC/GT with the greenhouse-gases-consuming syngas production process to provide a high efficiency and low carbon-emission hybrid power generation system design. The modeling and simulation is demonstrated by the software, Aspen Plus and Simulink. The fuel processing process connected a CO2 reformer behind traditional steam-methane reformer to provide syngas as fuel for SOFC stack and the simulation result showed that the fuel with only 1.7% CO2 content is beneficial to the SOFC stack. The 1-MW class hybrid power generation system performed high efficiency up to 86.5% and the total annual cost of the heat exchanger network has reduced 28.4% through the heat integration design. Finally, the dynamic simulation is successfully demonstrated by an integrated platform using Aspen Plus Dynamics/Simulink. Also, the effects of input change to the system performance and the nonlinear and asymmetry characteristics of the system have been observed.
