orange flames?
I built a brew system and plumbed in two of these. I'm using a 20 PSI regulator but have the gas controlled at each burner by one of these. Right now no matter how little or how much gas I give these burners using the controls I just get orange flames instead of the nice hot blue flames that I'm expecting even with the air intake orifice wide open. Has anyone had experience with using these burners (perhaps with the bayou classic SQ14) with a higher PSI regulator than suggested? Thanks
I would assume the issue may not be pressure, but air intake. Is there an adjustable manifold on the burner?
New rig, can we SEE SOME PICS??????

i've had this issue twice. both times were caused by poor air intake. once, the intake adjustment plate was not wide open. the other time i had caked up debris in the burner/air intake passage that had built up after a boil over on a previous brew. I soaked the burner element in some cleaner and cleaned out the passages. that fixed it.

this happned to me once. turned ouy to be a spider in the orafice. get a pipe cleaner and poke around. or make sure everything is clear. sometimes paint gets in there.
My burner has been acting up lately as well. I had a boilover a month or so ago, and the last 2 brews I have been getting the orange flame, I just went out to clean it, and I figured I have gotten so many batches out of it, might as well go with a new one.
So I just ordered one of these http://www.tejassmokers.com/castironburners.htm the top one, seems like a decent deal and good output, I just hope it is as quiet as my last one and dosnt soak up too much propane.
My vote is to fiddle with the air -intake.
I don't have exactly that bayou burner, but I have on similar to it.
It seems that when I want to adjust the flame a bit from roaring to....not so roaring I also have to adjust the air intake to keep the blue flames happy.
Of course if your regulator is pushing too much gas because its so far out of spec for the burner, you might not be able to get the intake to pull enough air. Try blowing in the intake to see if the flames get better for a second. That will hint to not enough induction.
Yeah, I know I need to post some pics, but the rig is still in the testing stage and isn't complete yet. I will certainly post a pic of the final product.

As far as the flames go, the air intake is wide open. I even went as far as completely removing the air shutter to open the holes as much as possible and I still get big orange flames. I know the burners aren't clogged with something because they are brand new and also by shining a light into the burner I was able to see no obstructions.
My first thought was that the problem might be that I'm using a 20 psi regulator (cannibalized from the high pressure jet burner that I've used for all my other brews) instead of the 10 psi regulator recommended for these burners, but I would have thought that the control valves at each burner would have been able to compensate for the extra pressure by simply dialing back the valve. I'm going to call Bayou Classic to see what their suggestions might be. I'll report back when I find a solution. Thanks for all the suggestions. Cheers!
Well, I finally figured out this big orange flame thing. I tried using a 10psi regulator per the manufacturers instructions instead of a 20psi regulator, but this had no affect. The solution turned out to be a burner jet, which is the connection between the plumbing and the burner itself. Below is a better picture. Basically, the gas needs to come out of a tiny hole instead of the full bore hole of a standard 1/8" pipe nipple. This allows for the appropriate air/propane mixture and the results are quite dramatic. I've posted pictures of the flame I got before and after installation of the burner jet. I'm so glad that the problem is finally fixed. I must say that I've learned a lot with this DIY project. I'll create another thread with pictures of my completed HERMS system. Cheers!

I am so ordering one of those wade! Holy crap! I have a mix of blue and orange, and can only imagine what this will do to my boil times and propane usage..
cheers to an oldie, but goodie thread!
Ricka, what are you using right now that gives you a mix of orange and blue flames?

I have a Kick-a-Banjo 4 with a 30 PSI regulator...I keep the air intake almost all the way open. This thing roars like a mother-F'er.... It's not a lot of orange, but nothing like what you have in that pic...
You burner likely has one of those jet already in it if you bought it as an entire burner. The only reason mine didn't have the jet was because I bought only the burner heads. Anyway, you may just want to take your burners apart and give them a good cleaning. Perhaps blow then out real well with an air compressor or something to get any crud that may have gotten in there.
Orange flames are due to a lack of oxygen. The Kick a Banjo burner has a really high PSI regulator on it. Is your regulator adjustable? If not then you may want to consider putting one on your burner to ever so slightly turn down the PSI on the regulator to equilibrate the gas/oxygen mixture within the burner. This might help you out with the but of orange you see in your flames. If you brew outside, though you may never get rid of the orange as any slight wind will throw off the flame balance. Cheers!
