gas burner flame goes out

[MichaelM]

So I got this great LPG gas burner for my all grain setup. Its similar to a bayou burner, but the type sold by Keg King. It uses an adjustable high pressure regulator.

I have had some problems with adjusting the air intake. When I open the air intake plate a little too much the burner makes a loud pop sound and the flames go out. Sometimes the flame will go out after about 20 seconds or so. I have had to adjust the intake to virtually closed( regulator half way open on a full cylinder). This seemed to stop the flame from going out.

Does anyone have similar experiences with this kind of burner or advice on how to adjust it correctly.

Thanks

When you are operating it with the air intake almost closed, is the flame blue or yellow??

I would take it back to Keg King and get them to check it out.

Hi Dicko. The flame is blue with a tinge of orange. Does the intake need to be opened up when i crank it up to max. I have had the regulator open halfway and the flame goes out if I open up the vent a bit more.

I should probably let them check it out.

If you are trying to over fire the burner, chances are you will have some orange in the flame.
Burners are designed to run at specific pressures to run at optimal efficiency. This will be written on the burner. Adjustable regulators are so the pressure may be correctly set with a monometer and then left.
For those running low pressure burners on higher pressure, it is not considered a safe thing to do.

As Glot indicates, there is a recommended pressure for the gas and there is an optimum opening for the the air mix device to achieve a clean blue flame.
The max setting for the regulator may not be good for that type of burner so try a lesser pressure and/or talk to the seller as suggested.

By the way, I would advise doing any testing and adjustments outside and in an area that is no affected by wind or draughts.

Cheers

Thanks for the help guys. I tried a few adjustments this weekend and managed to get a blue flame by adjusting the air intake and adjustable regulator. Managed to keep the flame going even in a breeze with some gusts.

I've seen one of those bayou types running on high pressure with flue flames 12 inches long and sounding like a 747.

Probably modified / designed for it.

Must've been modified. This one is rather silent even when almost completely open.

Nice, glad you got a good blue flame. My ring burner sounds like a jet now, yet to give it a practical application however.
