摘要

基于Aspen plus软件

建立了化学链高温空分制氧与IGCC集成的系统(CLAS-IGCC)模型，并以蒸汽作为化学链高温空分载氧介质

从载氧蒸汽过热度、氧煤质量比(氧煤比)、水煤质量比(水煤比)和载氧体等4个方面对CLAS-IGCC的性能进行了研究。结果表明:CLAS-IGCC效率随载氧蒸汽过热度增加而先减小后增大，随氧煤比增大而减小；水煤比对系统效率影响不大；以Mn3O4-Mn2O3为载氧体的CLAS-IGCC与以CoO-Co3O4为载氧体的CLAS-IGCC相比略具优势；CLAS-IGCC效率为45.1％

而采用常规低温空分制氧技术的IGCC效率为45.8％

因此

蒸汽型CLAS-IGCC集成效果不具优势。
