IR vs UV Boiler Flame Scanners and How They Work - Boiling Point

Today on the Boiling Point, Ritchie talks with Gerald Blain about the difference between IR and UV Flame Scanners and how they work detecting a flame. These sensors are the eyes into the boilers combustion chamber keeping tabs on the flame. Flame sensors keep the boiler room safe by confirming that there is a flame and not just filling the boiler with explosive gas. Learn how boiler flame scanner work and they are used.

Great thanks for sharing

Quite a scientific subject that may be tricky to grasp. But physics does help. I like the exaplanation on heavy oil being a 'dusty flame'', I've often missed or misrepresented that line and ends up in confusion and people not understanding it's comparison to pulverized coal - that they behave the same. Thx again.

[@md.abulbashar1820]

Great. More explanation would be great for the learner like me

[@cck0728]

Excellent video. Gas turbines also use UV flame detectors. Thanks for the video.

Hi, what are the proper tecnology for a Lim Kiln Uv or IR? The fuel that we use its bunker 6.

Would it be more likely to use IR scanner of Biomass or coal(very old biomass) ?

[@wareboilers]

Most likely it would be an IR scanner. The combustion environment for biofuels tends to be smokey which is the perfect setup for IR. Hopefully that answers your question and thanks for watching!

I recently troubleshoot a furnace with an issue in the U.V scanner so. I decide to investigate a bit. but, according with the manufacturer manual, when the tube discharge electrons when UV is present it rectify the a.c signal the create a small d.c current that can be measured by the controller. that's why if you jumper the scanner it's flow is an a.c for signal then will not work for that reason your controller can not amplify the signal until it become a d.c signal of 0 to 100 microAmps. is that true>?

[@judewolf7881]

Yes, rectification is an important tool to ensure that a short will not simulate a flame. That is because a short would allow AC current, never DC. Only proper detection would generate DC.

Dear sir
I am boiler engineer. I installed commission, repair different kind of steam boiler/ hot water boiler
I used different kind of combustion controller,
So I need your installation manual of
AFD model controller.
