| 英文摘要: |
| The combined cycle power plant features a higher efficiency, lower pollutant emissions and flexible load control, and it tends to substitute for the conventional power plant in the future. As an important installation in the combined cycle system, the heat recovery boiler, or heat recovery steam generator (HRSG), exerts a decisive influence on the performance of the system. This paper described the construction and thermal performance characteristics of a HRSG, and modeling techniques for HRSG design and performance analysis. On the basis of this, modeling principles of HRSG on design and off-design conditions were investigated, and the lumped parameter model, dynamic revised method and parameter selection were applied. A real-time numerical algorithm was selected to simulate the operation of HRSG accurately. |
