Accoding to production practice,This article discusses several issues of rapid cooling down the turbine,including the choice of fast-cooling mode,operation notes,economic and security. And it points out that air down flow cooling is safe,reliable and easy to operate.
根据生产实践,讨论了汽轮机停机快速冷却技术应用中的几个问题,包括快冷方式的选择、运行注意事项、经济效益和安全性等,指出顺流式空气冷却安全可靠,操作和控制方便,比较适合我国的电厂应用;机组采用快冷装置应尽量采用滑参数停机,当机组降低到一定温度后,方可投用快冷装置;论文还引用了文献,证明了采用快速冷却方式,只要操作合理,汽缸内壁的温差产生的热应力不会缩短汽轮机的使用寿命。
