"酸气中带氨会有什么后果？",,

"硫磺酸气中含氨，燃烧后会产生NO吗？对尾气加氢有影响吗？急冷水中PH值偏酸还是偏碱？",,

"正常就有含氨酸气啊！".,,

"你指的是哪个位置带氨，是入炉炉什么？".,,

"入炉酸气，硫磺的原料气".,,

"如果有酸气提装置，出来的酸气中本身就有氨啊。制硫炉烧氨火嘴，炉内内发生氨分解反应。所以有含氨酸气的硫炉温度一般控制在1581摄氏度。因为氨分解是吸热反应。".,,

"没有烧氨火嘴，炉膛温度在".,1111"之间。因为有氨精馏系统，所以控制目标是酸气中不含或尽量少带氨。实际的酸气氨含量检测数值也只在".,"之间。温度如果达不到".,"的话，缺氧燃烧会会产生NO吗？如果会的话，对配风和后面的流程有影响吗？".,,

"正常不会出现一氧化氮。因为氨气生成NO的反应是催化反应，燃烧炉没有没有金属催化剂。对后续的影响我想应该是结盐堵塞管道和设备吧！你这个温度可见应该是酸气浓度不高。是不是煤化工硫磺装置？".,,

"NO会使急冷水偏酸吗？比如SO3".,,

"酸气氨含量低的情况下不不会有太大影响。空气质量也会对尾气中氮氧化物造成影响比如雾mai天气".,,

"进口酸气含氨，进入硫炉后，参与燃烧反应。增大硫炉负荷。生成的促使二氧化硫进一步氧化为三氧化硫。和水。形成亚硫酸腐蚀设备。管道。亚硫酸和氨形成盐堵塞管道。还会使后系统的催化剂失去活性".,,

"会腐蚀设备。硫铵堵塞管道及设备。影响催化剂活性。等等".,,
