Abstract

Nowadays the combined effects of limited fossil fuel sources, global warming and economic crisis caused the increasing of benefit new systems for power generations. In this way fuel cell technology for many reasons as example like high efficiency, environmental friendliness, multi-fuel capability and… have been extensive research focus. Specially, the solid oxide fuel cell for the sake of higher efficiency, hot outlet gas and capability to use in combined cycle, are suitable for use in the power stations. In this work, by means of EES software, a solid oxide fuel cell and organic Rankine cycles have been simulated. Then, in order to increasing power and decreasing energy destruction, the model has been extended and combined cycles like SOFC-ORC, SOFC-GT and SOFC-GT-ORC have been simulated. Obtained results proved that when combining SOFC with ORC and SOFC with GT, the efficiency of cycle will increase about 6.62% and 12%. Also with combining the SOFC,GT and ORC, efficiency will increase about 16.53%.

Persian Title: تحليل و بهينه سازي ترموديناميکي سيکل ترکيبي GT-SOFC/ORC
Persian Abstract: امروزه محدوديت سوخت¬هاي فسيلي، گرم¬شدن زمين، بحران اقتصادي و...، تمايل به گسترش سيستم¬هاي جديد توليد توان را افزايش داده¬است و در اين ميان تکنولوژي پيل سوختي به دليل راندمان بالا، آلودگي کمتر، امکان استفاده از سوخت¬هاي مختلف، انعطاف در ميزان انرژي توليدي و... مورد توجه پژوهشگران قرار گرفته-است. در بين پيل¬هاي سوختي، پيل سوختي اکسيد جامد بدليل راندمان بالاتر و دماي بالاي گاز¬هاي خروجي و قابليت استفاده در سيکل¬هاي ترکيبي گزينه مناسبي براي استفاده در نيروگاه¬هاي برق مي¬باشد. در اين تحقيق به کمک نرم¬افزار EES به مدل¬سازي پيل سوختي اکسيد جامد(SOFC) پرداخته¬شده¬است. سپس به منظور افزايش توان و کاهش اتلافات سيستم با تعميم مدل، سيکل¬هاي ترکيبي SOFC-ORC، SOFC-GT و SOFC-GT-ORC مدل شده و نتايج حاصل مورد بررسي قرار گرفته¬اند. نتايج اين مطالعه حاکي از آنست که ترکيب SOFC با ORC راندمان را به ميزان 62/6 درصد و ترکيب SOFC با GT راندمان را 12درصد و ترکيبSOFC با GT وORC ، راندمان را 53/16 افزايش خواهدداد.
