将固体氧化物燃料电池（SOFC）与煤气化发电技术相结合，将是煤炭利用发电中最有前途的技术之一。气体净化装置产生的洁净合成气作为整体气化燃料电池电站SOFC的燃料。固体氧化物燃料电池产生的热量可以被余热蒸汽发生器利用来驱动蒸汽涡轮机发电。在这项研究中，拟议的工厂组成的煤气化炉和固体氧化物燃料电池的顶部的蒸汽涡轮机（ST），称为轻集成气化燃料电池（L-IGFC），进行了研究，通过使用白杨Plus软件来评估其性能。分析基于固体氧化物燃料电池模块，考虑了在中间温度下运行的电池在一定电流密度下的欧姆、活化和浓度损失。气体净化单元模型的影响也进行了研究。结果表明，所提出的常压L-IGFC装置可以在较低的热值范围内实现39-46.35%的电效率。
Integration of solid oxide fuel cell (SOFC) in coal gasification power plant technology would be one of the most promising technology in the coal utilization for power generation. The clean syngas from gas cleanup unit serves as fuel for SOFC in integrated gasification fuel cell power plant. The heat generated by SOFC can be utilized by heat recovery steam generator to drive steam turbine for electricity production. In this study, proposed plants consisting of coal gasifier and SOFC on the top of a steam turbine (ST), called light integrated gasification fuel cell (L-IGFC), are investigated thermodynamically by using Aspen Plus software to evaluate their performance. The analyses are based on the SOFC module considering ohmic, activation and concentration losses at a certain current density of the cell operating at the intermediate temperature. The influences of gas cleanup unit models were also investigated. The results indicated that the proposed atmospheric L-IGFC plant could achieve electrical efficiency in the range of 39–46.35% in lower heating value.
