摘要

摘要本文对带燃料电池(堆)的混合动力燃气轮机发电厂进行了设计分析。这项工作的目的是找到最有利的中等容量(约10MW)混合系统变体。在这篇文章中,对这种系统的两种变体进行了计算分析。该分析使计算两种变体的容量、效率以及其他参数(如烟气温度)成为可能。论文表明,这种混合循环理论上可以达到60%以上的极高效率。选择了最有利的一个进行进一步详细的热力学和流量计算。作为计算的一部分,设计了多级轴流压缩机、轴流涡轮机、燃料电池(堆)和再生换热器。然后对安装的盈利能力进行了分析,结果表明,该技术的发展现状及其成本使该项目无利可图。然而,几年来,人们一直观察到燃料电池价格下降的趋势,这就得出了混合动力系统将开始产生的结论。这可能适用于固定和海上应用。与电力传输相关的混合动力解决方案,包括燃料电池,对于小型汽车渡轮和较短的渡轮路线来说是真实的,非常有前景。

Design Analysis of Hybrid Gas Turbine‒Fuel Cell Power Plant in Stationary and Marine Applications
Abstract The paper concerns the design analysis of a hybrid gas turbine power plant with a fuel cell (stack). The aim of this work was to find the most favourable variant of the medium capacity (approximately 10 MW) hybrid system. In the article, computational analysis of two variants of such a system was carried out. The analysis made it possible to calculate the capacity, efficiency of both variants and other parameters like the flue gas temperature. The paper shows that such hybrid cycles can theoretically achieve extremely high efficiency over 60%. The most favourable one was selected for further detailed thermodynamic and flow calculations. As part of this calculation, a multi-stage axial compressor, axial turbine, fuel cell (stack) and regenerative heat exchanger were designed. Then an analysis of the profitability of the installation was carried out, which showed that the current state of development of this technology and its cost make the project unprofitable. For several years, however, tendencies of decreasing prices of fuel cells have been observed, which allows the conclusion that hybrid systems will start to be created. This may apply to both stationary and marine applications. Hybrid solutions related to electrical power transmission, including fuel cells, are real and very promising for smaller car ferries and shorter ferry routes.
