    Your Orifice on the regulator hose end is definitely causing the problem. Order or pick up new orifice and post results as per our conversation

    Boykjo here are the pics. First is the smoker, we're getting there but still have some finish work to do. Next is the yellow flame (yes - carbon monoxide), next is pic of the manifold, then the regulator asm, then the orfice out of the manifold flow control valve, and finally the orfice at the end of the regulator hose. This hose end orfice appears to be 2 to 3 times the size of yours, and may well be the problem. The black pipe diameter is 1" ID, with 1/8" wall. I did get some 1.5" ID black pipe today (it was already in process) and can build that up into a burner to try if necessary. Or I can see if I can find a reducer that will take the end of the regulator hose down to a smaller orfice. Boykjo - what do you suggest. And,,,thank you very much for the help.

    Nice rig...well thought out...keep in mind that yellow flames also mean carbon monoxide present, too.

    When looking for materials, remember that tubing is measured by the outside dimension while pipe is measured on the inside.

    I Just saw 1 inch diameter? Pipe should be 1 inch inner diameter 1 1/2 inch outer diameter. I am going to PM you my number. call me anytime this weekend.

    I'll post a pic of the regulator today (friday afternoon) so we can figure out how to turn this yellow stuff into blue stufff.

    Thanks for the quick response as to my "yellow flames". We have had a lot of fun building the smoker. It has come a long way from an unused fuel oil drum in a neighbors back yard, and an old boat trailer left in the weeds for years. It looks better than store-bought. I will get pics of it and the burner tomorrow. I searced for weeks looking for a tube burner that would work. Thank you for your design. You certainly will be on the list to come over for some good Carolina Smoked Pig.
    We tested the one 60" tube burner in the open - out doors. It was not in the smoker. It was a single 60" tube (1" dia), fed with an end cap manifold, per your design, connected via flexible gas hose to a high pressure regulator. The regulator was directly attached to a 1/2 full, 20# propane tank.
    Ultimately, we will have two independent 60" tubes, fed each with their own drilled out end caps, per your design, and fed from a "T" connection from a single high pressure regulator. The regulator will be fed from a 20# propane tank. Each "T" will have its own flow control knobs.
    I appreciate your help in solving the yellow flame problem. Tomorrow, I will check to see if the regulator has a hole in the end. It is brand new, so I suspect it is correct. I did notice that we could turn up the gas flow, and the yellow flames would really shoot out of the saw cuts. I could also almost shut of the gas supply and notice that the flames on the far end of the tube would extinguish, but almost think that the near end flames looked bluish. We tried covering up the 4 - 1/4 inch holes on the end cap, and noticed no difference in the yellow flames.
    I purchased a 30" black pipe (1" dia) today and a couple more end caps. So I can experiment per your suggestions, and closer to the length of your burner. Lookin' forward to the first smoke. Thanks Don

    Remove the pipe out of the drum and test the unit first preferably when its dark out. If it is blue then you are devoid of oxegen and need to drill two holes with a two inch hole saw at each end of the bottom of the barrel. I also installed a trap door in the middle of my barrel for oxygen and wood seasoning. You said you have two pipes. How are they laid out. You may need to build a manifold and run a gas mixer for each pipe. did you make a u burner with one mixer? It may be because of the black pipe. Not sure. what about your regulator? does it have the small hole at the end.I need some more info. I'm sure we'll have you burnin in no time. Now you know I will have to sample some of the tasty treats........... picture would be very helpful

    I hope I'm not too late with a question about building the tube burner. We are building a pig smoker out of a 250 Gal fuel oil drum, and I need 2 tube burners just like your design. I followed the plans with the exception that I used Black Pipe (couldn't find the untested pipe). I also made the pipe 60" long (instead of approx. 20"). I started my first band saw cut about 10" from the gas/air end cap (instead of 4"). My problem is that I have a yellow flame, meaning incomplete combustion. Any suggestions on how to correct this? Thanks for the help. Don

    Metallurgy, I know what you mean about not having the time to do what you want to do. I had planned to spend tomorrow playing in my shop, but I've gotten side-tracked. Oh well, like they say, "Life is what happens while you're busy making other plans." Anyway, glad to see that you're still at it, posts some pictures of your projects when you get them done.

    Boykjo, this pipe burner post is excellent. Thanks for posting and thanks for the pics.
