| 摘 要： | 整体煤气化联合循环是一种先进的洁净煤发电技术。本文应用#［1316］分析方法，研究IGCC中七个子系统（空分、气化、净化、压气机、燃烧室、透平、余热锅炉及汽机)的#［1316］损失分布，指出系统中最大#［1316］损失过程为煤气化、燃气轮机燃烧和空分过程。同时，揭示了系统随不同空气整体化和氮气回注的规律。这些研究可以指导下一代IGCC系统的改进

| Abstract: | Integrated Gasification Combined Cycle is consideredas one of the advanced clean coal power technologies. Here, we haveinvestigated an IGCC on the basis of exergy analysis,and clarified the distribution of exergy destruction in sub-systemsincluding air separation unit, coal gasifier, coal gas clean-up unit,air compressor, combustor of gas turbine, gas turbine, heatrecovery steam generation and steam turbine. The study also pointsout that larger exergy destruction take place in the processes ofgasification, combustion in GT, and air separation, andso does the change of exergy destruction distribution with the airintegration degree and the nitrogen injection ratio. This investigationwill be valuable for the synthesis of next-generation IGCC |
