燃气锅炉燃烧器常见故障及解决方法

点击:0发表时间:2018/03/07

春节过去了,寒冷的冬天也要离开亚博直播app了,陪伴亚博直播app整个寒冬的锅炉快要“光荣下岗”了。在这漫长的三个月中,锅炉燃烧器都有哪些问题而罢工呢?
1、接通电源,按启动、电机不转   
故障原因:(1)气压不足锁定;(2)电磁阀不严,接头处漏气,检查锁定;(3)热继电器开路;(4)条件回路至少有一个不成立(水位、压力、温度以及程控器是否通电起动)。   
排除措施:(1)调整气压至规定值;(2)清理或修理电磁阀管道接头;(3)按复位检查元件是否损坏以及电机电流;(4)检查水位、压力、温度是否超限。
2、启动后前吹扫正常,但点不着火   
故障原因:(1)电火气量不足;(2)电磁阀不工作(主阀、点火阀);(3)电磁阀烧坏;(4)气压不稳定;(5)风量太大。 
排除措施:(1)检查线路并修复;(2)换新;(3)调整气压至规定值;(4)减小配风,减小风门开度
3、点不着火,气压正常,有电不打火   
故障原因:(1)点火变压器烧坏;(2)高压线损坏或脱落;(3)间隙过大或过小,点火棒位置相对尺寸;(4)电极破裂或与地短路;(5)间距不合适。  
排除措施:(1)换新;(2)重新安装或换新;(3)重新调整;(4)重新安装或换新;(5)重新调整 。
4、点着火5S后熄火
故障原因:(1)气压不足,压降太大,供气流量偏小;(2)风量太小,燃烧不充分,烟色较浓;(3)风量太大,出现白气。  
排除措施:(1)重新调整气压,清理滤网;(2)重新调整;(3) 重新调整。
5、冒白烟   
故障原因:(1)风量太小;(2)空气湿度太大;(3)排烟温度较低。
排除措施:(1)调小风门;(2)适当减小风量,提高进风温度;(3)采取措施,提高排烟温度。
6、烟囱滴水
故障原因:(1)环境温度较低;(2)小火燃烧过程较多;(3)燃气含氢量高,过氧量大生成水;(4)烟囱较长。   
排除措施:(1)减小配风量;(2)降低烟囱高度;(3)提高炉温;(4)排烟温度较低风门在控制状态下停机 风门位置开关信号没有反馈到程序信号 检查风门接线是否松动或开关是否失灵。
