How to Make a BBQ Burner - Propane

[Music] alright so in this video I'm going to show you how to make this 2 burner for a project I'm working on I needed to make some burners I figured this would make a great standalone video so here it is so the burner is on right now very simply it's basically a 2 with an intake and an orifice something like this that shoots the propane through it connected to a propane hose and a regulator down here and that's the burner nothing to it ok it was only as simple as that there is a little tweaking and the size of the orifice hole is really critical to besides of the tube I'll talk about that after I just wanted to show you a quick overview with this burner so what we have we have a propane regular down there just connected to a 20-pound propane tank that regulator is just a standard barbecue one high output barbecue one lets low pressure so it's under 1 psi then I have it hooked up to a ball valve here flare fitting to the ball valve and then into 1/8 pipe pipe nipple which the pipe net bolt is then connected to a plate like this and then there is a novel an oarfish hole drilled into a quarter-inch end cap for a 1/8 n cap this is all brass fittings so and then that is hooked up to this reducer that goes from an inch and a half down to 3/4 of an inch to a one inch stainless steel tube with a whole bunch of bandsaw cuts cut into it and then the end is welded shut and then a piece of plate was welded on so could be for use for maps but anyways so I still need to tweak it a little bit I get a little bit of yellow on it but it's not too bad this is at a 1.2 orphis hole and I'll talk about all that here in the build but that's about it there's nothing to it yeah I get really good heat output from this to light it very simply just turn on the propane a little bit to hear it just ignite [Music] I'm going to manufacture the burner this intake is going to be the bell housing and I need a way to remount the orifice to it so I'm going to weld on some mild steel so I can have some holes in this you'll see how this will work but I got to preheat this cast iron and then well lit to the mild steel all right so the well this I'm going to use some stainless steel MIG wire and ideally you could use nickel rod with a stick well rip I'm going to use stainless steel here it works pretty well this is nothing really structural so this will be okay just be practice in place [Music] this is a piece of 3/4 inch wide 1/8 mild steel bar stock same as the stuff that I welded on the back of this bell housing or this producer that will be mounted to the tube burner and I'm going to drill a hole here which will then thread this knit type nipple that will fit that with this it gets 1/4 inch NPT tap so I'm sure the hole tap this and then I'll make an orifice flat which will then hold on to this easy [Music] all right so correction this is a 1/8 NPT thread for this pipe nipple I'm going to use water cutting oil and just tap this hole [Music] [Music] Oh [Music] [Music] so drilled a hole in a 1/8 cap for the pipe nipple for this guy here so it's a 1/16 of an inch hole which will fit on like this but before that it'll thread on for this plate that I've made so it'll fit on like this then this cap will fit on this side [Music] that's the whole assembly [Music] this is a one inch in diameter by 1/16 inch thick stainless steel tubing this will be the burner tube and I've already done some testing I created this guy here this guy here I test it with the orifice with a 1/16 inch orphis I've clamped down on this side that seals up I'm gonna replicate it on the other tube this one was sacrificial I tried drilling holes initially here to try to make holes on both sides that was just way too much work way too much drilling it's just especially such a small drill bit and stainless steel work hardens like a son of a so I'm going to cut flat that's what I've landed on so what I will do is I'll replicate the same thing on this tube here [Music] I'm going to mark the DS as one centimeter apart find that was a good amount so I did on this old one [Music] [Applause] [Music] [Music] [Music] so because this intake isn't big enough back here I'm drilling in some extra holes for air hopefully that will provide enough air for this burner because there's a lot of slaps slots cut out for a for the burner it's using a lot of air to mix with the propane so I'm getting a yellow flame so I'm going to see how it works with these extra holes these are three different end caps one eight end caps that I've drilled out to varying different sizes for the orifice holes so this one is one millimeter this is one point two millimeters and this one is 1.3 millimeters I don't know what that is in a number size for a drill bit that's the drill bit set that I have so that's what I'm working with in case you're wondering this is the drill bit set that I have and get this off of Amazon for a couple of bucks but it's got all the way from point three up to one point six millimeters so anyways after some experimentation I've figured out that one point two millimeters is the optimal orphis hole for this burner for this two burner that I've made out of one one inch by one they stainless steel to me so I'm going to show you the different offices and the size of the flame because there's an optimal I figured out that there's an optimal amount of airflow air mixture with propane for the size of the tube you can't physically get any more air unless you force the air in to get a clean burn so you'll end up with more of a yellow flame instead of a nice blue burning flame so I'm going to show you right now what that looks like alright let's start with the 1.3 millimeter [Music] so as you can see here it's got too much orange of the tips that will be the flame coming out there this is still experimenting so 1.3 no good just way too much orange go to 1.2 [Music] I figured out that this is probably the optimal flame for it the optimal novel size for this size two burner and its intake I tried drilling more holes to get more air into it but it really doesn't make a difference even if I constrict off this it doesn't change the burner so it's really limited by the size of the tube and how the fuel and air mix with the size of the orifice so I'm really limited there's a ratio there I don't really exactly know what it is but after just do some trial and error I've landed on something decent at least so that's one point to a little bit of orange but not too bad it won't make the bottom of the griddle or your barbecue stood up too badly so it's not bad it's a trade-off between power and performance versus the dirty flame although is burning it off the hole at that orange link so that we're switching it off to one millimeter [Music] this is at 1 millimeter and it's just it burns nice and clean this is at max though that's not bad it was just a low powered barbecue or a grill but I want something a little more fun so I'm going to go over the one point two millimeter so one millimeter is just a little too too small for for what I want and I need to clean up the holes on the burner as well so you can get a nice clean aflame but that works well so one point to it is but just for fun I had drilled out a 1/6 hole and this is far too big but it does produce a big roaring big flame [Music] this is 1:16 and it's way too big I can't get nearly enough air in it to get a nice clean burn but you definitely got lots of power and hot I can feel it from here but see it's a really dirty flame you can't get enough with the venturi effect in these and materi burners it's not drawing enough air in at the same time for they don't have enough velocity I guess or again it's the tube size there's a ratio there I don't know what it is but for me one point two millimeters should work just fine [Music] all right here's the end product so what do we have we have a low-pressure propane regulator down here connected to a 20-pound propane bottle with a rubber hose connected to flare fitting which then connects to a ball valve then the ball valve is used to control the propane flow this is connected to the ball valve is connected to a 1/8 tightening old brass pipe nipple for now NPT and then it's connected to this this assembly here which is a plate with attacked 1/8 NPT hole right here and then an end cap with a one point two millimeter orphis hole drilled into the cap thread it on to the nipple which I just removed it from just for testing here I just have this long pipe nipple in here whereas this has a downward for the project I'm working on but you could imagine will be like this it will just face downward so I can route the propane so from there we're hooked up to a 1 and a 1/2 inch reducer black iron reducer down to 3/4 of an inch and then a one-inch pipe stainless steel pipe with a whole bunch of slots cut into it with my bandsaw use a hacksaw grinder although I find the bandsaw width is a really nice width and then at the end is just clamped shut and then weld it and then I welded on this piece of stainless steel just so to be have a hole drilled in it for mounting and that's it for the burner control very easily with the ball valve [Music] now [Music]
