Flame Rod Working

Flame Rod 

Flame

Flame has certain characteristics that we are use for detecting Flame. The detection device, coupled with a suitable flame control mechanism produces a signal.

Flame Measuring Method

There are some methods that are used for Flame Detecting.

a.Flame Rod

b.Visible light sensors

c.Infrared sensors

d.Ultraviolet sensors

e.Thermal Effect

 Flame Rod

Flame Rod is an instrument that are used for flame detection. Flame rod mostly used on Pilots. Flame rod are specific for Gas flames. Oil Flames are not Suitable for Flame Rod. Flame rod have quick response to flame failure.

Working Principle  

The Working Principle of Flame Rod is Ionization current flame detection.

Its ability of flame to conduct current when potential applied across it. When there is no Flame, the resistance between electrode is maximum. But the presence of flame resistance decrease and the flow of current increase through the flame rod and it indicate the presence of Flame.
