[". 水煤浆気化上上管间隙堵塞的原因

2017-02-26View Original

Thread Content

最近気化炉带水严重,装置被迫停工。检查发现上上管间隙堵塞严重,请问是因为带水造成间隙堵塞?还是因为带水后导致间隙堵塞。大家欢迎讨论!

三维隙出现堵塞,就说明上升管或者下降管有变形,特别是下降管。出现变形向外凸起的地方,变形凸起处就容易成为积灰中心,导致间隙大量积灰。所以进去检查上升管和下降管在积灰部位的情况,然后启动激冷泵,看看下降管的水幕分布情况。如果真的有变形,这个情况可能是你激冷水不足或者激冷环有喷水孔堵住了导致下降管水幕分布不均匀。检查检修激冷环。

不懂等待大神指导。学*。

激冷水流量没有变化,也是存在下降管结渣的现象。

気化炉带水严重是氣化炉液位维持不住了停车的吗?

は的,昨天另一台炉因带水严重停车,进去检查间隙又堵死了。

需要强调的是,我们的下降管下部没有钟罩,锯齿也较小。

会不会是炉溫有点低,导致不能液态排渣??

应该是排渣不畅造成的。
