Exergy Analysis of Efficiency Augmentation of a SOFC Combined with a Water Injection Gas Turbine Power Plant Ali Abdollahi a bdollahi@me iut ac ir April 26 2010 Department of Mechanical Engineering Isfahan University of Technology Isfahan 84156 83111 Iran Degree M Sc Language Farsi A A Alemrajabi Assoc Prof Supervisor rajabi@cc iut ac ir Abstract Nowadays utilization of high efficiency and low emission of pollution power production systems is one of the primacies and attractive topics for researchers Solid oxide fuel cells are such systems the capability of them to integrate with power cycles such as gas turbine cycles proposes a hybrid system for future power plant This study examined the performance of a natural gas fed tubular solid oxide fuel cell combined with a conventional recuperative gas turbine power plant Then the overall system performance was analyzed by analyzing the different components separately and further applying thermodynamic laws for the entire cycle The results of performance of the power plant for certain operating conditions were compared against those available in the literature The comparisons provided useful verification of the thermodynamic simulations in the present work Then in contrary with the previous studies the base SOFC GT hybrid system was combined with water injection method Next second law based performance analysis including irreversibility determination of the hybrid system was performed Also a parametric study was performed to illustrate the effects of various parameters such as compressor Pressure ratio fuel mass flow rate entropy generation rate SOFC power electrical power and CO 2 emission By means of this system it is possible to reach a first law efficiency around 62 and the second law efficiency about 60 The overall power the first law efficiency and the second law efficiency of this system were increased up to 6 5 4 5 and 5 6 respectively Key Words Solid oxide fuel cell Gas turbine hybrid Water injection performance exergy CO2 emission
