Green Zombie Posted February 1, 2016 Share Posted February 1, 2016 I am in need of some advise. I recently built a 1" propane torch that worked great at first, now I seem to be having an issue with the propane burning inside the tube close to the jet (.035 mig tip) and not at the end of it where it should be. It was before but after some adjustment of fixing a leak I'm now having this issue. here's some photo's of the torch and how it did burn but now flame is burning inside the tube as I said and close to the jet. is there a set point at where the jet should sit maybe to burn properly? Any help would be greatly appreciated. Thanks. Quote Link to comment Share on other sites More sharing options...
beammeupscotty Posted February 1, 2016 Share Posted February 1, 2016 Yes, adjust the jet in or out until you can maintain a burn at the end of the torch. Make sure it is aiming straight down the pipe and is centered in the venturi. The sort of mounting arrangement you have used for holding the jet in place is going to make keeping it aimed right and positioned right a bit difficult.

I thought that might be the problem as when I soldered the jet and it's seat back in place it was sitting higher than previously when torch was working properly. I will try and post results.

JHCC Posted February 2, 2016 Share Posted February 2, 2016 Might not want to point that at those louvres. You could end up with some very undesirable ignition. Quote Link to comment Share on other sites More sharing options...

So my problem wasn't the positioning of the jet, it was the jet itself. I went to a .025 from a .035 which was much too big and pushing way to much propane up the tube for this size of torch. I am however going to put an 8" tube on as well rather than the 6" as the torch heats up quite fast and I think a longer tube would help. Thanks for the help. It is much appreciated. Now on to the new melting furnace Quote Link to comment Share on other sites More sharing options...
Frosty Posted February 3, 2016 Share Posted February 3, 2016 Your jet is WAY too far down in the works. A properly tuned 1" burner should be running a jet in the 0.040" range give or take 0.005". Though that is a linear so probably 0.035"-0.040" is more realistic. Who's burner build instructions did you follow or did you just wing it after seeing one on Youtube? There are several sets of good burner constructions directions available but you have to pick One set and FOLLOW the directions. Frosty The Lucky.

Green Zombie Posted February 6, 2016 Author Share Posted February 6, 2016 The burner is working fantastically with a .025 mg tip now. The jet tip sits where the tube and the reducing coupler meet so its positioned correct as far as I can tell and it's a 3/4" burner . No issues with set up now but thanks for the reply.

Mikey98118 Posted February 8, 2016 Share Posted February 8, 2016 Green Zombie, the following will sound harsh; I don't mean it that way, but...No, it is not working fantastically! I can tell this much from your description of the burner as "working great at first", after looking at your photos. The first photo shows a (probably 1/2" pipe size burner (not one inch, unless you have giant sized hands) with a reducer fitting that is too small, on a pipe that is a bit short). That pipe should be nine times the measured inside diameter of the pipe in length if you want proper fuel gas and air mixing. Your photo also shows the flame nozzle out of proper alignment with the mixing tube (pipe) axis; drill and tap three more holes to the rear of the existing three set screw holes, so that you can properly aim the flame nozzle.Also, I don't think you remembered to include a spacer ring at the rear of your flame nozzle; it will never work properly without one. this advice comes from the guy who invented all those updates to Riel burners that you're trying to employ. Your burner will be "running fantastic" when it produces mostly a single primary flame envelope, without a white combustion envelope behind it (just a clear space), with very little secondary flame, and no third flame envelope at all. Pipe call-out sizes are smaller than actual outside diameter; they are even smaller than actual inside diameters. Read the call-out sizes listed on the bins you choose your parts from; don't go by what you see. Quote Link to comment Share on other sites More sharing options...
Mikey98118 Posted February 8, 2016 Share Posted February 8, 2016 How do you choose the right size of spacer ring? Using schedule #40 pipe, or its tubing equivalent, the spacer ring is the next size up from the pipe you are using as the burner mixing tube. The flame nozzle consists of the next larger pipe size from the spacer ring. You will probably need to do a little filing or power sanding to get the spacer ring to slide freely on the mixing tube, and a little more filing to get the flame nozzle to press-fit over the spacer ring. I would also recommend using stainless steel pipe or tubing for the flame nozzle; not mild steel. Quote Link to comment Share on other sites More sharing options...
Green Zombie Posted February 9, 2016 Author Share Posted February 9, 2016 Hi, it's not really that complicated, I did follow the torch set up as done by King of random in youtube. It's a simple burner for melting silver and gold and aluminum, the air intake has a double cap on the back side to adjust air/fuel mix. It's really pretty simple and not to sound harsh myself but too many make things too complicated when it's quite simple. I attached a photo of it burning now. It'll do just fine for my needs Quote Link to comment Share on other sites More sharing options...

It will come off when introduced to the melting furnace Quote Link to comment Share on other sites More sharing options...
Frosty Posted February 11, 2016 Share Posted February 11, 2016 So THERE Mike, he's following the King of Random's plans! I don't even know WHY he's asking us anything. Seriously I don't believe I can help him so I'll just . . . Nevermind. Frosty The Lucky. Quote Link to comment Share on other sites More sharing options...
Frozenforge Posted February 11, 2016 Share Posted February 11, 2016 Green Zombie, just for your info Mikey98118 and Frosty have years of experience with propane burners and was involved with the development and improvement of this type of burner that King of Random has posted a version of. Their suggestions are based on years of experience and experimentation. These burners will "function"within a large range of tolerances with a wide range of results in temperature and efficiency. An honest mistake I assume. Quote Link to comment Share on other sites More sharing options...
Green Zombie Posted February 11, 2016 Author Share Posted February 11, 2016 Years of experience or not, the Puritan attitude put forth with snide remarks are uncalled for. I'm not a blacksmith nor a professional in this field and got into building this for fun and to melt a little metal. I've always gone by the KISS Rule of thumb. After all It's not a piano I'm building here but this forum, or this experience with this part of it anyway, has made it un-fun. Its ok though, I appreciate anyone's help butt I'll be moving along respectfully. To those that enjoy the hobby, good luck and happy burning Quote Link to comment Share on other sites More sharing options...
Mikey98118 Posted February 15, 2016 Share Posted February 15, 2016 Well, no; the KISS principle recommends not over complicating your work plan.

Mikey98118 Posted February 15, 2016 Share Posted February 15, 2016 Green Zombie, Actually, I'm still trying to point out the simple truth to you, but am noticing that while you have accused the rest of us of being "snide," you in fact are doing all the name calling. Go on ahead and "let it all out." Maybe there is someone left on this thread who hasn't noticed your attitude yet; might as well do a thorough job while your at it Quote Link to comment Share on other sites More sharing options...
Mikey98118 Posted February 17, 2016 Share Posted February 17, 2016 ianinsa, It was kind of you to cover for me, but I don't mind admitting that I don't know, or care about, acronyms in general; "Pig Latin" is of no importance to me either; KISS is an acronym that is useful, and so I bother with it, but most acronyms, as used today, are a just another example of slang.

Mike, Guys: You're getting sucked into this Troll's game. He's just one of those sad people who can't find satisfaction unless it's causing strife. His thread has nothing to do with burners it's just about HIM and a sad SAD attempt to gain attention. Let's just ignore the foolishness and let him pay his own game by himself. I am.

Mikey98118 Posted February 17, 2016 Share Posted February 17, 2016 Actually, There is something of value to be discussed here. If you look at his first photo, you'll see that the threaded reducer fitting is crooked. One of the many reasons threaded reducers were avoided by most builders (dating clear back to Aussie burners), was the steadily deteriorating quality of these mostly imported parts. You can find workarounds for many problems, but a lopsided fitting can only be avoided. Since black pipe is steadily being being marginalized by plastic pipe, choices of good fittings are reduced all the time. It is much better to check the fittings before purchase by threading them onto a pipe nipple, and if you can't find a good reducer, going online to search for a thigh quality stainless steel or heavy wall aluminum reducer fitting, which can be slipped over steel tubing and pinned in place with screws. Press formed (no thread) concentric reducers also have smooth interior surfaces, with superior shape to cheap sand-cast threaded reducers for better laminar flow.

Green Zombie Posted February 18, 2016 Author Share Posted February 18, 2016 And yet you're all still going on about it...... Lol if mods could cancell my account that would be great as I can't seem to do it from mobile settings, and there seems to be nothing of value here for me. Thank you.
