350MW亚临界汽轮机FCB运行的探讨

Discussion on FCB Operation of 350MW Sub-critical Steam Turbine

通过对一种典型的350 MW亚临界汽轮机组结构特点的分析,阐述该型机组在FCB工况运行时对汽轮机结构以及寿命的影响,推荐350 MW亚临界汽轮机组在配置高—低压两级串联旁路时的两种FCB工况运行方法及要求。

Through analyses structure features of typical 350MW sub-critical steam turbine,the influence for structure and lift of steam turbine when unit under FCB working condition is discussed.Two type FCB working conditions and requirements for 350MW sub-critical steam turbine when configure high-low pressure two stages series by-pass are recommend.
