所谓二次燃烧就是本应该在烧焦罐大量燃烧的被带到稀相段燃烧,导致稀相段温度超高。加入助燃剂是最快捷的方法,但应该先调整操作,提高烧焦罐的烧焦强度。加入助燃剂,是否提高主风量,看再生器里氧含量,氧含量低了,可提高主风量。

降风量会降低氧含量,导致烧焦效果下降,尾燃会加剧。

取决于是否完全再生。完全再生发生二次燃烧肯定是提主风量、提高再生床温、加助燃剂,不完全再生的话发生二次燃烧就是降主风量降低烟气过剩氧含量以免后路CO继续燃烧

没看清标题,加助燃剂就是完全再生得提主风量

建议楼主发布主题的时候最好把装置的具体形式写清楚,便于大家帮你分析问题! 在这个主题里有个很关键的因素即装置的再生方式,见有海友已经根据具体情况做了分析,说明有人已经注意到这个问题!

既然加了助燃剂应该就是完全再生吧,俗称的富氧。加助燃剂之后提高主风量,增加氧含量;提高再生器压力,增加烧焦强度;不完全再生的情况下,发生二次燃烧就是氧含量高了,要降低主风量,不过要随时观察再生剂颜色,防止风量降多了造成碳堆。

大家基本说的都比较清楚了,加入助燃剂后主要提高富氧再生的能力,其次看再生器顶部氧含量,一般低于1.0%以下容易引起烟道尾燃,烟机入口烟气温度上升,就要提主风。

你们氧含量控多少?根据氧含量分析下是不是主风不足。
