摘　　要：燃气—蒸汽联合循环发电技术可实现化学能梯级利用,具有很高的效率。余热锅炉处于燃气轮机和蒸汽轮机之间,对联合循环系统效率产生重要影响。本文概述了燃气—蒸汽联合循环发电技术的原理和组成,重点介绍了余热锅炉的结构和热力性能等方面的特点,并对影响余热锅炉性能的有关因素进行了阐述。最后,对余热锅炉的研究方向进行了讨论。Gas-steam combined cycle has been encouraged to use in utility power station in many parts of the world due to its high efficiency which is achieved through the fuel chemical energy in graded use. Heat recovery steam generation （HRSG） is one of the most important parts of this system and its system and performance have a great affect on the combined cycle system. In this paper, we introduce the gas-steam combined cycle power generation technology, depict the HRSG structure and thermodynamic characters, and elaborate the influence factors on HRSG. Finally, the future study direction of HRSG is discussed.
