R4348 A/1026火焰监测器R4348A1026工作原理
R4348 A/1026高速烧嘴带有点火小烧嘴(又称值勤烧嘴),所装火焰监测器是为检测小烧嘴的火焰,一旦灭火立即报警。在这种情况下,可以使用非接触式的紫外火焰监测器,也可使用接触式的导电电极式火焰监测器。
R4348 A/1026火焰监测器可以单独使用,而通常是与自动点火器联合使用。该装置由点火器、监测探针、监测器三部分组成。当点火电源打开后,点火器变压输出15000V以上的高压电,使点火棒与烧嘴(接地极)间产生电弧而点燃烧嘴。耐高温的探测针接触火焰获得信号,通过监测器立即推动继电器切断电源,停止打火。火焰熄灭后,先吹扫残余烟气,再重复以上动作,直到获得稳定火焰为止。同时,火焰监测器还可并联出一对触点接到炉子控制室,参与联锁报警或计算机控制系统的工作。
R4348 A/1026同理,非接触式火焰探测器也可以与自动点火器组成类似的联合装置。
