Energy and Exergy Analysis of Hydrogen-Fueled Combined Cycle

The hydrogen-fueled combined cycle has been proposed. Including the balance of the material and energetic flows, the thermal efficiency and the exergy efficiency are introduced to evaluate the overall performance of the cycle. A proper parametric analysis is then performed in order to investigate the influence of the main working parameters on the cycle efficiency. The main factors such as temperature and pressure have strong effects on the attainable performance according to the results; moreover, it comes to the conclusions that the large amount of exergy losses are caused due to the process of combustion, it is necessary to raise the combustion temperature to reduce the losses.
