摘要

在燃气-蒸汽联合循环(联合循环)机组上实行汽轮机深度滑参数停机(深度滑停)尚缺乏成功先例。通过在GE9F级分轴式联合循环机组上完成汽轮机一次深度滑停试验

使汽轮机缸温降到253℃

效果良好。探讨了在联合循环机组上实行深度滑停的特点与制约因素

认为只要充分发挥联合循环的自身特点

操作得当

在联合循环机组上也能有效地实施汽轮机的深度滑停。

Abstract

The realization of deep sliding parameter shutdown of steam turbine in unit with gas-steam combined cycle is still short of successful precedents.Through test of one deep sliding parameter shutdown for the steam turbine completed on a split-shaft combined cycle unit of GE9F class

the temperature in cylinder of steam turbine has been reduced to 253 ℃

having good effectiveness.An approach to the features and restraint factors for realizing deep sliding parameter shutdown on units with combined cycle has also been carried out.
