tcoliver Posted March 17, 2007 Report Share Posted March 17, 2007 Hey DJ, or anyone else. After I drilled out the burner hole I now am getting a large yellow flame. I have noticed on my last few pizza cooks where I use gas only I am getting black soot on the pizza and I think this is attributed not getting a good blue flame. So what does it mean when you get a yellow flame, too much oxygen or too much gas? And how can I correct this if possible. Thanks. Quote Link to comment Share on other sites More sharing options...
Firemonkey Posted March 17, 2007 Report Share Posted March 17, 2007 Too rich Yellow flame means you are burning too rich - confirmed by the soot you found. Check your burner for obstructions, and you might check your regulator as well. Quote Link to comment Share on other sites More sharing options...
tcoliver Posted March 17, 2007 Author Report Share Posted March 17, 2007 Well actually I enlarged the original hole in the vlave in order to get more gas and more heat. My regulator is not adjustable. Do I need to get an adjustable regulator or is there another way to fix this? Quote Link to comment Share on other sites More sharing options...
Firemonkey Posted March 18, 2007 Report Share Posted March 18, 2007 The key question is "was the flame ever blue?" If it was before you drilled it, then you will need a smaller orafice, adjustable regulator, or some other way to get a leaner fuel:air mix. If the flame was once blue after your drilling, then you likely have spiders, or ash or something blocking your air intake. I dont have Dennis' burner here, so I dont know if it is as simple as getting a new part, or if you would have to fix what you have. If you had to fix it, you may be able to braze it and redrill a smaller hole. You may try something simple like just opening the draft door a bit to get more air in there? You say you drilled it to get more heat, just curious - how much heat were you getting from it? From Dennis' new drying process post, it looks like the burners are capable of 800* Quote Link to comment Share on other sites More sharing options...
DennisLinkletter Posted March 18, 2007 Report Share Posted March 18, 2007 Bury the needle way past 800º You say you drilled it to get more heat, just curious - how much heat were you getting from it? From Dennis' new drying process post, it looks like the burners are capable of 800* With no modification at all, I can bury the needle way past 800º with a regulator on a LPG tank. I did not pay much attention to the flame quality or color but will check it out on Tuesday, Monday is a national holiday. Quote Link to comment Share on other sites More sharing options...
tcoliver Posted March 18, 2007 Author Report Share Posted March 18, 2007 Even with the hole drilled out I can only get about 400 degrees. Dennis what type of regulator are you using? I think mine is 5 psi (maybe 10 psi), non adjustable. The soot only started after I drilled out the hole. I never really had a good blue flame but I think I just have a lot MORE flame now and it is producing a lot MORE soot. Maybe I need a better regulator.

DennisLinkletter Posted March 24, 2007 Report Share Posted March 24, 2007 This can easily bury the needle I have these burners on a large LPG tank with a adjustable volume regulator. My guess is that the pressure on all LPG tanks are the same. Here it is turned up real high. This can easily bury the needle on the 800º TelTru, maybe 1,000º or more. Now that's cookin' with GAS!

cruzmisl Posted March 24, 2007 Report Share Posted March 24, 2007 HOLY SHE***T! Mine doesn't look like that at all! How do I obtain such a gorgeous flame? What is this regulator you speak of Quote Link to comment Share on other sites More sharing options...
DennisLinkletter Posted March 25, 2007 Report Share Posted March 25, 2007 Unless we are smelting ore.. I've received a PM that I'm probably pushing about 200,000 to 300,000 btu with my burner at this setting. Basically pumping a low pressure burner with a high pressure gas regulator. All is fine till the flame goes out, then you have what would be a dangerous situation. They also said they would be scared as hell to pump that much gas into an enclosed space. We don't turn the burners up that high inside the Komodos.. Unless we are smelting ore.. (which voids your warranty;-) PLEASE NOTE, I DO NOT IN ANY WAY RECOMMEND USING YOUR BURNER THIS WAY... That was just so Firemonkey could see flame color and what's possible.. KIDS, MOMS AND DADS.. PLEASE DON'T TRY THIS AT HOME.. Quote Link to comment Share on other sites More sharing options...
cruzmisl Posted March 25, 2007 Report Share Posted March 25, 2007 Well, if I had propane I'd do it anyway desite the risks. Probably never use it like that either but it is cool to look at. Fortunately, I have natural gas hookup which I don't believe has the pressure required to perform such theatrics......or maybe it does Quote Link to comment Share on other sites More sharing options...
PaulR Posted March 25, 2007 Report Share Posted March 25, 2007 I just spend 45 minutes getting my WSM up to temp for cooking... I WANT A KK + GAS GIZMO!! PS The luverly wife hasn't agreed just yet.... Quote Link to comment Share on other sites More sharing options...

rbv Posted March 25, 2007 Report Share Posted March 25, 2007 For those of you who prefer charcoal... A friend of mine pointed me to this website. Pretty cool, until the local authorities decided he wasn't licensed to use explosives... http://digg.com/general_sciences/Real_Men_Cook_With_Liquid_Oxygen_-_Video Quote Link to comment Share on other sites More sharing options...
tcoliver Posted March 26, 2007 Author Report Share Posted March 26, 2007 Here is my burner flame. I guess this is the difference between a high pressure and a low pressure regulator. DJ suggested using lava rocks in the coal bowl. I will try that and see if I can get rid of the soot. I want to reiterate this only happened after I drilled out the hole in the valve.

cruzmisl Posted March 27, 2007 Report Share Posted March 27, 2007 Here is a picture of mine using natural gas. I had to drill it out since I had the propane burner but it works well. I hope this helps for reference. Quote Link to comment Share on other sites More sharing options...

Dang, Tony, looks like your burner needs a little blue pill. No worries though. I think Dennis can get those for you. hehehe. Quote Link to comment Share on other sites More sharing options...
tcoliver Posted April 14, 2007 Author Report Share Posted April 14, 2007 Update Ok, I finally revived my burner, I purchased a new adjustable high pressure regulator and used the original orifice. My results are similiar to Dennis'. And yes I could pin the needle if I so desired. I purchased an adjustable 0-20 psi regulator from Tejas Smokers however this was probably overkill and I could have used a 10 psi regulator. I have had to turn down this regulator as I don't want to have an accident. At full open this thing could heat a house. DJ you were right in you analysis that this would produce a LOT of fuel. I promise to be carefull. I wouldn't suggest this for the average cooker but I am now satisfied and I cooked a pizza tonight with no soot. Thanks deej for your help.
