| 摘 要： | 基于Aspen-Plus软件建立了SOFC电池堆的模型,设计了不回收CO2的SOFC复合动力系统,针对系统特点,提出了CO2零排放的SOFC复合动力系统,对这两种系统的性能进行了详细的比较和分析。CO2零排放系统利用纯氧燃烧方式得到的燃烧产物只有CO2和水蒸气,通过冷凝得到高浓度的CO2。与带CO2脱除的常规电厂相比,极大地降低了回收CO2的能耗。通过对主要参数(燃料利用率、蒸汽/碳比、运行压力等)进行优化,详细分析了各主要参数对系统性能的影响。本文研究成果将为进一步研究高效的CO2零排放SOFC复合动力系统提供有益的参考。

| Abstract: | Based on the Aspen-plus soft,SOFC stack model is established.The SOFC hybrid power system without CO2 capture is designed.Then,the zero CO2 emission SOFC hybrid power system is proposed.The performances of these two systems are compared and analyzed.With the mode of pure oxygen combustion,the outlet gas of zero CO2 emission SOFC hybrid power system is composed of only CO2 and steam,so it is easy to get CO2 with higher concentration by means of condensation.Compared with the conventional power system with CO... |
