600MW汽轮机的优化启动

Optimal start up on 600 MW steam turbine

根据湖南华电长沙发电有限公司机组现状,在安全、合理的情况下,对汽轮机启动冲转时间分配及启动参数进行了合理调整,并在实施过程中全程跟踪,使汽轮机的中速暖机时间由4.0 h缩短为2.5 h,提高了暖机效果,节省了启机能耗,增加了上网电量,并根据实际暖机情况,进一步提出增加汽缸烘干装置的优化措施。

According to the status of Hunan Huadian Changsha Power Generation Company Limited,this paper adjusts allocation of turning time of turbine startup and startup parameters under a reasonable condition. In the process of implementation,mediumspeed warming has shortened from 4. 0 h to 2. 5 h,which improves warming efficiency and on-grid energy. Finally,this paper proposes a optimization measure which is to add cylinder drying device.
