350 MW汽轮机组三段抽汽温度高原因分析及处理措施

Reasons and Treatment Measures for High Extraction Temperature in the Third Stage of a 350 MW Steam Turbine Unit

近年来,火电企业通过热电联产实现了节本降耗、提质增效及产出综合效益目标,目前正值此类企业高质量运营阶段,应持续提升其全要素生产率。文章以此为背景,针对某有色金属有限公司350 MW汽轮机组三段抽汽温度高现象,分别从技改方案与处理效果两大方面对其处理措施进行了具体探讨。

After entering the period of Chinese path to modernization reform,thermal power enterprises have achieved the goal of cost saving,consumption reduction,quality and efficiency improvement and comprehensive output benefits through cogeneration.The new era is when such enterprises should continue to improve their total factor productivity at the stage of high-quality operation.The article uses this as a background to explain the phenomenon of high extraction temperature in the third stage of a 350 MW steam turbine unit of a certain non-ferrous metal limited company.The specific treatment measures are discussed from two aspects:technical transformation plan and treatment effect.
