Abstract
In order to achieve the goal of low carbon emission in the cogeneration system, a fuel cell gas turbine hybrid power system with ammonia as the working fluid was proposed. By establishing a model of hybrid power system, the performance analysis and exergy analysis of the system were carried out, and the efficiency of the system was compared with that of a hybrid system with LNG as fuel.Resultsshow that the efficiency of the system can reach 72% within the optional range of fuel utilization and air excess coefficient, and the system has high exergy efficiency at the design point. The exergy loss mainly occurs at the fuel cell and air heat exchanger. And the efficiency of this system is higher than that of the LNG-fueled hybrid system at the same fuel flow rate.
