| 摘 要： | 对生物质气化-固体氧化物燃料电池/燃气轮机发电系统的特性及不同运行参数对系统性能的影响进行了分析。生物质气化为以水蒸气为气化介质的基于UNIQUE概念的流化床气化、高温净化系统,建模中采用了化学动力学模型,并以萘作为焦油成分。基于所建立的系统模型,分析了生物质含水率和燃料利用率等参数对系统性能的影响。结果表明,与其他生物质应用技术相比该系统具有较高的能量转化效率,在200 kW规模,生物质含水率为20%时,电效率可以达到47%。生物质含水率增加会降低系统的输出功率,系统效率下降明显;SOFC燃料利用率提高时系统输出功率变化不明显,但系统效率会明显提高。

| Abstract: | The aim of this work is to numerically analyze the performance of a integrated power plant, which is composed of a biomass gasifier, a fuel cell and a gas turbine. The biomass gasifier is a steam fluidized bed system based on the UNIQUE concept. The chemical kinetics model is applied for the analysis of gas composition production, and the naphthalene is chosen as the tar composition. Effects of different moisture contents in the biomass and fuel utilization on the system performance are studied. The results show that, the biomass gasification-SOFC/MGT power plant can obtain an efficiency above 47% at the 200kW with the 20% of biomass steam content, which is higher than other biomass power plant. The increase of steam content in the biomass can decrease the system power and efficiency. The system power changes insignificantly with the increase of fuel utilization, while the system efficiency can increase significantly. |
