玉环电厂超超临界1000MW汽轮机组快冷系统的应用
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
