燃气蒸汽联合循环余热锅炉是整个联合循环的重要组成部分之一,余热锅炉动态特性研究对整个燃气蒸汽联合循环具有重要作用。通过分析余热锅炉的热力特点,提出了燃气蒸汽联合循环余热锅炉动态特性研究的意义。然后,根据国内外的相关研究成果,从物理模型、数学模型和仿真方法三方面进行了分类和探讨。最后,对余热锅炉动态特性的研究发展提出建议和展望。

The Heat Recovery Steam Generator （HRSG） in Gas Steam Combined Cycle （GSCC） is one of the key components of the entire combined cycle. It plays an important role to entire Combined Cycle system. Based on the characteristic of HRSG, including significant heat resource, change in status, load matching and adapting to the combined-cycle characteristic of Quick Start, it proposes the significance of dynamic research of HRSG in GSCC. Secondly, including the thermal physical models, the mathematical models and simulation methods, the research results in the domestic and foreign are classified and discussed as well. Finally, it figures out the proposals and prospects which the dynamical characteristic research of HRSG will prevail.
