摘要(Abstract)：

提升超临界二氧化碳（S-CO_2）锅炉调峰能力是实现S-CO_2燃煤发电机组灵活运行的关键。研究S-CO_2锅炉动态特性有助于优化锅炉运行控制。以西安热工研究院有限公司5MW S-CO_2循环发电机组锅炉为研究对象，基于热力学和传热学原理，建立了S-CO_2锅炉动态仿真模型，并利用机组运行数据验证了模型的可靠性。基于仿真模型，开展了燃料量、工质流量、工质温度等不同边界条件阶跃扰动下S-CO_2锅炉的动态特性分析。结果表明：S-CO_2锅炉具有较大的热惯性，不同边界条件扰动下锅炉出口工质温度稳定时间不同，且随着边界条件扰动幅度增加，稳定时间变长；随着S-CO_2锅炉热负荷升高，锅炉出口工质压力下降，出口工质流量会出现瞬时增大现象。

关键词(KeyWords)： 超临界二氧化碳锅炉;仿真模型;动态特性;边界条件
