Flame detection and extinguishing protection device for combustion furnace

The flame detection and extinguishing protection device mainly includes an explosion-proof box, a flame detection controller, UV flame detection probes, and monitoring cables. The control box is equipped with controller modules, relays, air switches, and other components. The controller module supplies 220V output switch signals and can also interlock and control the fuel valve. When the flame detector probe detects no fire during an unexpected shutdown, it is processed by the controller and alerted by an audible and visual alarm.

The HY-XB system flameout protection alarm control box is a flame monitoring and alarm system specially designed and developed according to the needs of industries such as petrochemicals, metallurgy, coal chemical, ceramics, etc. This product is equipped with a flame monitor, which is simple, reliable, and easy to use and maintain. It is suitable for flame monitoring and extinguishing alarm of various gas, fuel burners, and toasters.
