摘要

华能玉环电厂的超超临界1 000 MW汽轮机组故障时

为缩短停机冷却时间

采用快速冷却(快冷)系统。2号机组故障停机时

应用了快冷系统

缩短了10天检修工期。该厂4台机组在停机检修中累计投入快冷系统11次

都取得了较好的效果

节约了大量的检修工期。

Abstract

In the event of trouble occurred on ultra-supercritical 1 000 MW steam turbine in Huaneng Yuhuan Power Plant

in order to shorten the cooling-down time for shutdown of the unit

a rapid cooling-down system had been adopted.During the time of shutdown due to trouble occurred on unit no.2

the rapid cooling-down system had been used

shortening the repair by ten days.Through application of said technology onto the other three units

the rapid cooling-down systems have been accumulatively put into operation for eleven times in the repair period during shutdown of the four units

saving large amount of time in the repair period.
