S109FA联合循环机组滑参数停机分析

The Analysis of Sliding-parameter Shutdown in S109FA Combined Cycle Unit

介绍了GE公司S109FA燃气-蒸汽联合循环机组滑参数停机的操作过程及注意事项,阐述了此阶段燃气轮机排气温度的控制和汽轮机热应力的控制,以及避免此阶段燃烧方式频繁切换的操作过程。

This paper introduces the operation and the precaution of GE S109FA combined cycle unit during the sliding-parameter shutdown. And it introduces the gas turbine exhaust temperature control, the steam turbine thermal stress control and operation process of prevent combustion mode frequently transform at this stage.
