铁素体布莱登汽封在600MW机组上的应用

The Application of Ferrite Brandon Steam-glanding for 600MW Unit

本文针对东汽600MW超临界汽轮机本体的结构特点,对铁素体布莱登汽封在高中压部分实施节能改造情况进行阐述,铁素体布莱登汽封改造后,在提高机组安全性的同时,高中压缸效率有较明显的提高,对同类型汽轮机通流部分节能改造具有较好的借鉴意义。

This paper describes the energy saving with using the ferrite Brandon steam-glanding on the high and middle pressure cylinders according to the structural characteristics of the dong fang turbine＇s 600MW supercritical the turbine, the safe of the unit is enhanced synchronously and the high and middle pressure cylinders efficiency is obvious improve after the reconstruction of the ferrite Brandon steam-glanding is implemented.It has batter reference significance for the same type turbine throughflow part of the turbine.
