超超临界二次再热1000 MW汽轮机性能及优化建议

Performance and optimization recommendations of ultra supercritical double reheat steam turbine

根据国内已投产的超超临界二次再热1000 MW汽轮机的性能试验和运行实践,对超超临界二次再热1000MW汽轮机的热经济性和运行灵活性等主要性能与超超临界一次再热1 000 MW汽轮机性能进行比较分析并提出改进建议,为今后超超临界二次再热机组优化设计、性能提升、灵活运行提供参考。

This paper reviews the main performance of the 1000 MW ultra supercritical double reheat steam turbine, which has been put into operation, such as economy and operational flexibility. And compared with the performance of ultra supercritical once reheat steam turbine, the factors affecting the main performance of the two reheat steam turbine and the improvement direction are put forward, in order to provide a reference for the optimization design, performance improvement, starting and debugging and flexible operation of the ultra supercritical two reheat unit in the future.
