Homemade pipe burner venturi is simple and easy to make. Our pipe burner venturi build uses very few parts. Our pipe burner venturi works just as well as a purchased venturi. We show you the easy construction in this video.
We connected our homemade pipe gas burner venturi up to our homemade burner and it worked perfectly from the start. This going to be used in a syrup cooker. It really does put out some heat!
This DIY pipe burner venturi for propane build parts only cost about $30.
We show you the easy to build a homemade pipe burner venturi from start to finish. With a little work and using our DIY propane burner venturi build instruction, you can build the venturi in about an thirty minutes.

@useful.knowledge Ай бұрын

@thebigboss024 Hi. I don’t think sealant is required. The gas/air is going out the slits and you don’t really have a build up of pressure. I have ran these for many hours at a time without any issues.

This is great man! I was just thinking the whole concept of the venturi is so simple i can't believe they charge so much for it, i was a bit hesitant to make one myself since explosions and stuff lol but after this video i think i'm going to try! Two questions though... can i use natural gas? And can i simply have one tee joint but with the venturi one at a 45 degree angle so the flow is better and the air doesn't have to make a 90 degree turn? sorry if i didn't explain it correctly, english is not my first language.

@useful.knowledge 2 жыл бұрын

Hi. It’s more about the gas flowing straight into the burner under pressure and the resulting in flow of air. It’s sounds like you are thinking about using a Y connection. I could see that working but you will most likely have to adjust the orfice to get the flow required to make it work. It would definitely be worth a try and really cool if it works!!

Do you think you can take this set up except have the 1& 1/4 pipe running parallel to the venturi pipe? so basically using a another pipe nipple and tee into the center of another 1 & 1/4 tee and run the burner pipe parallel instead of in the end? Thanks for any help. I did the same set up with a smoker I built cut the slits in the pipe except that the gas line comes in to the middle of 2 smaller sections of pipe but I do not have the venturi and it burns dirty and yellow flame and when I raise the lid the flame will go out and I want to try to build this venturi.

@useful.knowledge 4 ай бұрын

Hi. I think it would work. About your other setup, yellow flame is usually the orfice or the amount of air. I would change the orfice drill out size and make it smaller.

If you didn't have enough slits in your burner then couldn't gas come out your tee? So how do you know how many slits to cut? Do you really need 2 side inlets? Would 1 work fine?

@useful.knowledge 8 ай бұрын

I honestly do not remember where I learned the 1.5” spacing on those slits. It was many many years ago but it works. I also use that spacing on my 2 ft version and it will throw the heat. We have a video on that one and you can see it running in the latest syrup video. You could probably get away with not using a T and just use an elbow. The drilling might get tougher to keep inline.

Ok. I checked the 2ft burners with the homemade venturi. They worked just the same as with the bought venturi. It did have a small yellow tip but that was when I was really putting the gas to it. So for full disclosure, my smaller burners have at least an 18” throat, 2ft of burner slits, and then about 12” of pipe before the end cap. I had the pipe in the barn for years with threads already on each end so I just used what I had. I made pics of the burner running a few minutes ago.

Hey, ive been doing syrup for a few years all on propane. I want to build this setup to go with the 3 chamber pan I built but I have a few questions, your video covers the venturi (Great) now the flame looks pretty small for boiling sap (as from your first video I know you used this for that). 1st why 1 1/4 pipe if I run 3 burners that size thats alot of pipe to keep full off my 100# lp tanks.my pan is a 2x4 progressive design pan.Second if you boiled off that burner can we see that. Curious how much has that thing eats in an hour.

@useful.knowledge 2 жыл бұрын

Hi. I did a lot of research and 1 1/4 seemed to be the size that most folks used. That includes some old timers that I asked. I have a 2x6 pan that was really just too big for the amount of sorghum juice that I’m producing. I downsized to a 2x2 pan that easily holds about 10-12 gallons of juice at a time. I made new pipe burners and used the same venturis as the first pipe burner video. It worked great. The pan is so thin that I didn’t have any issues with the boiling. Here is a link to the syrup making video. kzfaq.info/get/bejne/h5ydoMiirtPPh4k.html I didn’t even change out the orfice size for the 2ft pipe and they still worked great. For the original long burners in the first video, drilling out the orifices is the only way I was able to get the burn that I wanted. I messed up a few but they are cheap. About the propane usage, it’s surprising not as much as I expected. I’m the syrup video, I had 3 of the 20lb tanks and I didn’t even use half of each. Hope this helps.

You could cut down the cost of your venturi by ditching the nipples 8-32 screws and pipe clamps. Just drill and tap the lip of the tee 6-32 to screw the washers to with short 6-32 screws.

Doesn't look like you need the washers. Might want to try some advertising fridge magnets to control the air

Hi. You really don’t need the washers for this length of burner. When I first built it, it ran perfectly with no washers. I was thinking that it was just pure luck. A different length of pipe burner or just propane quality could create the need to control the air. I came up with the washers and the small screws because it was easily adjustable and I wanted to give folks ideas. I think anything that could be rigged up to control the air and is stable would work. Your magnet idea would work.

I just made one of these venturis for my grill. I am having some issues though. I drilled out the orfice to 2/32” and am using 1” pipe. I made a bulkhead through the side of the grill using 2 1” floor flanges and threaded the Venturi on one end, and inside the grill I have a 24” pipe. The first 4 inches are not slit, then after I have slits every inch. When I went to light it, it did burn nice and blue. I noticed over time with the lid shut that the flame either yellows out or blows out when I open the lid. I kept the exhaust stack on the grill fully open, and even tried keeping the flue on the other side of the grill open as well. How might I fix this? I am currently on a regular set 20lb grill regulator. I thought about spacing the orifice further down the T into the throat of pipe, and I also thought about getting an adjustable regulator. My goal is to have something quick to use and cook on/ searing some steaks, that neither the charcoal or pellet grill can do quickly

@useful.knowledge 2 жыл бұрын

Hi. Yellow flame is indicative of not getting enough air. When you close the lid are you somehow shutting off some airflow into the venturi or just the pipe?

@useful.knowledge 2 жыл бұрын

Ok my next thought is that your throat needs to be longer. From my experience, an at least 8 inch throat is key. On my two foot burners that bush for my small syrup pan, my are closer to 10 in. To troubleshoot this, I would just purchase a coupler and a short pipe nipple to add in between the existing throat and venturi to see if that corrects the issue.

Hi. In most cases, yes. It really depends on the burner length and how hot you want to run it. I built a venturi for my 2ft burner that I wanted to run hot. For this, I used a 1 1/4 x 2” coupling. The 2” on both sides really allows the air to be pulled in.
