3. Flame : Flame Detection is very important in every industry. Flame has certain characteristics that we are use for detecting Flame. The detection device, coupled with a suitable flame control mechanism produces a signal. Heat Production Expansion of gases Production of by-product of combustion Emission of light (infrared or ultraviolet) Ionization around the flame

4. Flame Measuring Methods ; There are some method that are used for Flame Detecting. Flame Rod Visible light sensors Infrared sensors Ultraviolet sensors Thermal Effect

5. 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. They work on Ionization Principle. Flame rod have quick response to flame failure. Coaxial cable used with flame Rod. They have three Components Flame Rod Coaxial Cable Electronic Module (Relay)

6. Working Principle ; Flame Rod Work on Ionization principle. When gases burn, Heat , IR/UV rays and ions generated. Flame rod work on 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

7. Flame Rod Sensor Circuit ;

8. Specification : Service For Gases on Pilot Power 80 to 300 VAC Output Micro amp DC Response Fast 1 to 4 sec Flame Rod Length As per Required Special Cable Coaxial High Frequency Signal Digital Contact SPDT

9. Flame Amplifier A Flame Amplifier provide Voltage to flame electrode. The flame electrode is immersed in flame to sensed. The current thus generated by the flow of electrons through the flame to the ground is detected by the controller for presence of flame
