摘要(Abstract)：

构建高效、无污染的动力发电系统是解决目前能源紧缺和环境污染问题的有效手段。以Capstone公司生产的C65型微型燃气轮机为核心发电部件，耦合了太阳能驱动氨气分解制氢的热化学过程，实现了可再生能源和氨气化学能之间的多能互补，采用有机朗肯循环（ORC）作为底循环回收微型燃气轮机（微燃机，MGT）产生的烟气余热并发电，实现能量梯级利用。在化工模拟软件Aspen Plus中构建了详细的模拟流程，进行系统热力性能分析，结果表明：通过太阳能和氨气的互补提高了富氢合成气热值，微燃机输出功率为89.95 k W，比参考系统中的C65微燃机多24.95k W；该系统在设计工况下的电效率达到了44.81%，?效率为47.97%，分别比参考系统高出8.51百分点和9.67百分点；系统中最大的?损部件为燃烧室，占到了总?损的41.67%，其次蒸发器和回热器分别占14.31%和11.15%；系统电效率和?效率随着太阳能集热量的增加分别呈减小和增大的趋势。该研究结果可为以氨气为燃料并耦合太阳能的分布式微燃机发电系统提供参考。
