摘　　要：余热锅炉作为联合循环系统中的重要设备，在许多联合循环分析中没有得到足够的重视，为了分析联合循环系统的性能，有必要研究有关余热锅炉建模方面的一些问题。通过分析余热锅炉的部件构成，将余热锅炉内所有部件分为三类：省煤器、蒸发器和过热器。讨论余热锅炉在设计工况和变工况下相关部件的建模。模型具有模块化和面向对象特点，符合可视化建模环境对模型的要求。最后给出的建模和仿真实例，体现了灵活方便的特点。The heat recovery steam generator (HRSG) is one of the important equipment in combined cycle, but up to now, sufficient attention has not been paid to its modeling. In order to improve the static and dynamic performance study on combined cycle, through analysis of the constitute of HRSG, all components can be classified into three types: economizer, evaporator and superheater. Further, the modeling principles of HRSG on design and off design points are introduced. The models have the features of object oriented and modilar, which can be used in visual simulation environment. Finally, a visual simulation program is given out as well.
