摘要
通过介绍大型超临界汽轮机的特点及现有技术,对1000MW级超超临界汽轮机在通流部分、轴系、运行参数和机组旁路系统的选择上提出了一些选择依据。并明确指出单轴、5缸6排汽或4缸4排汽,参数为25.0MPa/600℃/600℃或25.0MPa/600℃/620℃是比较适合我国国情的首选。
Through the introduction to the features and existing technologies of large size supercritical pressure steam turbines,this paper puts forward some bases for the selections of flow part,shaft system,operation parameters and by pass system of unit,and elearly indicates that,single shaft,5 cylinders,6 exhausts or 4 cylinders,4 exhausts,with parameters of 25. 0 MPa/600℃ /600℃ or 25. 0 MPa/ 600℃/620℃,are comparatively appropriate for China's actual situation,may be as the first selection.
