利用汽轮机快冷装置提高机组投运率

Using Steam Turbine Fast Cooling Equipment to Increase Unit Rate

大型汽轮机停机后如果采用汽缸自然方式,达到停运盘车条件的等待时间比较长,不仅影响检修工期,延长机组停运时间,还将减少机组的运行时间和电量。特别是作为单机运行的机组,缩短停机时间,带来的经济效益将更为可观。电厂通过合理采用快冷装置不仅取得了巨大的经济效益,而且在保证机组的安全启动方面也收到了很好的效果。

Large steam turbine after shut down if adopting the natural way of cylinder,it takes longer time to wait for achieving conditions of stop turning gear,and it not only affect repair time,prolong the shut down,it also reduce unit operation time and power.Especially as a single operation of the unit,shorten downtime also helps the economic benefits.The power plant by using the fast cooling unit not only achieved great economic benefits,but also got a good result in guarantee the safety start-up for units.
