Based on the first law of thermodynamics and the second law of thermodynamics, a more specific exergy analysis method of IGCC system is given through a concrete example. The exergy efficiency of each system component and Exergy loss rate is given to determine the working conditions of the more important parameters of the state, the system reflects the important relationship between the integrity of the system and its components of the exergy efficiency, the specific formula for calculating the rate of fire The calculation results of the adopted examples are analyzed and explained, and the suggestions for improvement are given. From the exergy point of view, the position of each component in the system and the impact on the overall efficiency of the system are analyzed. The optimal combination of IGCC system is provided in accordance with
