摘要
以300MW空冷汽轮机低压长叶片设计开发为例,阐述了大型空冷汽轮机长叶片的技术特点,对叶高、反动度、频率、背压限制、结构等关键要素的选取原则作出说明,为新的空冷低压长叶片的设计提供参考。
This paper introduces the characteristics of LP long blade for large capacity air-cooling steam turbine with an example of 300MW Unit. Guide lines for determining main properties such as blade height, reaction,frequency,back pressure limitation and structure are described.This also offers reference for future development of LP long blade for air-cooling turbine.
