Triple-T #77 - How to make a ribbon burner

Excellent video - a ribbon burner is in my future. The switch of my burner from venturi to forced air was already life-changing. ;) Thank you for addressing PSI vs flow rate. I wish I could share that explanation with everyone who wants to build a forge burner. PSI is almost meaningless for measuring gas flow without further information - it took me a long time to figure that out too because the common way to compare burners in almost all forums is to use PSI.

[@TyrellKnifeworks]

Definitely collect all the parts before you start. I'm torn which is easier and cheaper, the fiber blanket vs the soft fire bricks. I am thinking the firebricks is easier and cheaper and probably safer, but on the next one I'm gonna do poured refractory over kaowool instead. I'll see how it goes. Thanks for watching!

[@BurnsBlades]

@@TyrellKnifeworks probably overkill, but I've seen some builds with kaowool against the steel, then soft firebrick, then hard firebrick floor that can be changed out. Like this, they said the exterior remains quite cool (comparatively) and because the kaowool is held in place with the brick, not much need for refractory other than to hold the bricks together.

[@bransonsgeneralstore]

A possible way to measure efficiency is by weighing the propane tank. Difference in weight after an hour of running the forge multiplied by BTU/lb of propane will give you the consumption in BTU/hr. Leaving a scale around the tank is useful anyway to check how much propane is left in it, tare weight should be stamped in the ring around the valve.

[@TyrellKnifeworks]

Yes, that’s certainly a way. Thanks for watching.

[@White_devil1980]

That’s great information about gas forges as I’m using a coal forge and I’m not that knowledgeable about gas forges 🖖

[@TyrellKnifeworks]

Glad it was helpful, Robert. Gas is certainly cleaner but has its issues like anything else. Thanks for watching.

[@Danger_Noodle_Pliskin]

As a MIG welder, I tended to prefer telling people how many litres per minute (of argon/co2/mix) I ran on welds, I found that better as it took tank pressure out of the equation. Dunno if that helps, but thought I'd share the info.

[@TyrellKnifeworks]

Yes, that’s flow rate and exactly what I meant. Most people don’t have that on their propane reg so it’s not really something people will relate to unfortunately. Thanks for watching

[@dkironworks4037]

Nice explanation on the PSI. Majority of the community definably have a misconception on this. More even heat for the same pressure based on burner design? Or is it more heat for similar gas usage to a venturi?

[@TyrellKnifeworks]

A ribbon burner is definitely more efficient. Not so much its shape but because it uses forced air vs a venturi. The venturi design requires a lot of gas be blown at higher pressure to cause the venturi effect which draws air down the tube. You also see more gas being burned outside the forge ("dragon's breath") because its not mixing well inside the forge. So it's really the forced air that gives you the gas economy. The ribbon burner equally distributes it across the length of the forge for a more even heat. I hope that helps. Thanks for watching.

[@simondoug]

Awesome video Denis. I am pretty sure you and Brian House are in my head. Brian releases a vid on how to wire up a VFD at the same time I am wiring up my first VFD. You release a video on making a ribbon burner as I am getting the components together to build one. One question for you. How much of that refractory did you end up using for the burner? I am thinking of buying that type and then using the rest of it to line the forge I am building. I would imagine the 50 pound bag will be more than enough but just want to check.

[@TyrellKnifeworks]

I think I used about 5 or 6 plastic cups worth from a 55lbs bag, so you have plenty. Good to hear the videos are timely and helping you out. 👍. Thanks for watching, Doug!

[@chefpaolo3190]

please can you explain how did you connect the needle valve to the 2 inches pipes? i saw the set screw you did... how did you seal it ?

Спасибо, очень понравилось.

[@TyrellKnifeworks]

Спасибо за просмотр!

[@Bob-hf2np]

Great video. Is there any risk that the flame could bleed back into the part of the ribbon burner behind the refractory front through the straw holes and ignite the gas air mixture there?

[@TyrellKnifeworks]

It’s the same with any propane burner. The blowing force pushes the gas out the holes where it ignites. There are times if you get the forge too hot (2300F+) than the burner is so hot it can ignite the gas inside it. That’s called a tube ignition. It just makes a funny sound. All you need to do is turn the gas down/air up and it goes away immediately. It’s not dangerous. Thanks for watching.

[@Bob-hf2np]

@@TyrellKnifeworks Thanks for that information

[@krissteel4074]

Very cool, ribbon burners apart from their efficiency also work a bit better at altitudes so if you're a hillbilly they'll pump out more BTU's than the equivalent set up of Venturi burners. About the only weirdness I ever found with them was they sometimes take some real fiddling to get down to idling flames where its just ticking over, first came across them in big industrial ovens and I think that's were they originated from. Someone needed to cook a pizza in 8min

[@TyrellKnifeworks]

Really? I have no problem at lower heats, just turning down the air does it. Have a gate valve on the air is a huge plus. Thanks for watching, Kris.

[@ThomasShue]

My pipes are 2”, so to using a 3” square pipe as the base, I need to put as many Mc Donals straws that will fit in the 2” pipe, the. This will determine the length of the burner so I can fit the straws in 3 rows? (I’m assuming)

[@TyrellKnifeworks]

The length of the burner is your choice. The number of holes in the burner is how many straws that can fit in your 2" pipe opening. Thanks for watching.

[@BrighamKindell]

im going to be building a ribbon burner. Is there a special way you have to introduce the propane into the air flow? how close to the burner do you want that?

[@TyrellKnifeworks]

Usually you want it at least 12" before the burner and preferably have a 90 degree bend after its introduced. That helps it mix thoroughly with the air. I hope that helps.

Hello Tyrell, which steel is better for a Bowie knife out of these three steel, 5160, bearing steel, or an old file?

Any of those steels would be fine. Which one can you heat treat the best? The file is probably 1095 which can be tricky. The bearing steel is likely 52100 which is also a bit harder to work and heat treat. 5160 is trivial to heat treat so if you’re new, I’d say go with that. 👍

I don’t think that would work, it probably wouldn’t burn even. I think you’d want two burners with a single massive fan with pipes that split or two fans and control them independently. Brian House of Housemade just showed a similar one on IG with two burners off a single large fan. Check that out.

Can see it is possible to get the refractory mix inside the straws. Why not use full length straws and hold them in place with hardware cloth?

[@TyrellKnifeworks]

You need to put the metal burner on top so the straws cannot be full length. Thanks for watching.

[@AerialLensVideo]

Thanks! I hope I'm not driving you crazy with questions, BUT need to ask your opininion on what cracked the original block (KastOLite-30 maybe?)? I simply cannot afford that wonderful Greencast stuff - YIPE$! What if I reinforced the casting with tiny stainless steel fibers or something to help prevent such a crack? Oh, and by the way (maybe this will benefit YOU for a change), many ribbon burners can "backfire" or pre-ignite inside the block if they become to hot inside after an hour or so. I have a tiny little 1-1/2 x 6 burner which does that. For that reason, I'm maybe going to paint a little bit of IR reflective Metrikote (cheap version of Satanite high aluminum coating) on the outer face of my burner.

[@TyrellKnifeworks]

Kastolite30 is just fine. What cracked mine WAS a piece of steel reinforcement in fact! That steel inside heated up and the burner cracked right through that location. I had the same thought process you are going through thinking it would make it stronger but didn't account for heat. So don't do it! I am finding I have that issue with the backfiring of the burner on my new forge. If I have more air pressure it doesn't happen though. I get it when the flames are "lapping" more. If there's enough air pressure that all the flames on each hole are solid, it doesn't seem to occur. I do find I have to take off the back door on my forge after about an hour or it gets too hot inside when I'm forge welding and this occurs. 😜

[@jvmiller1995]

If you want to compare the gas usage between ribbon and venturi burner place the bottle on a scale for a hour. weigh it before and after and you can figure how much gas you are using per hour. Do it on both burners. So how many cfm is your blower running. It looks like it burns real good. I keep wanting to up grade but have not done so. But you have about the best design from what I have seen. I am thinking of molding mine with a bit of a taper on it so it always seals good and I do not need the flange around the top.

[@TyrellKnifeworks]

Yes the weighing approach works but you really need to do a test for a few hours at least to get a measurable difference. I’ve since replaced this forge with a circular one. Check that video.

Hey Tyrrell, great update on your ribbon burner progression. I built mine following your previous build. Thanks I absolutely love it.

G'day Mate. If you weigh the gas cylinder before and after use. Then subtract Start weight by End weight you get the quantity of gas used in kg or lb. Also if you time the run and divide the quantity of gas used by the run time you end up with the flow rate in lb/hr or min. You can work the cost of gas used if you need to know that to.

[@TyrellKnifeworks]

Yes, I guess you could do that, but that’s a lot of work. I’m lazy and if I cared that much I’d just buy a flow meter. 😜. Thanks for the tip though, Daniel.

[@mattgriffin8108]

For 3:15, I don't wanna be that guy... but you could also just use πr² = Area to calculate how many holes and how big to make them.

[@TyrellKnifeworks]

But then you have to calculate the size of a the pipe, then the size of the straw, then divide... that's way more complicated than just putting a bunch in the pipe until it fits. 😉. Thanks for watching.

[@Mucidamascusblades]

Thanks for sharing. I am about to build one and I really needed to see one of these made. Now, about the pressure/flow rate, those are 2 different things. The forced air (especially the ribbon) burners can work at lower pressure as they don't need the output pressure from the nozzle to create the vortex to suck oxygen in. The size of the orifice is, as you said, bigger in a forced air system so the flow rate (gallon per minute) is still adequate even at 1 (for example) psi. That's how I was taught how the forced air system works, but I might be wrong, since I am not that smart. Do you have any equation to determine the size of the pipe in relation to the size of the forge? Thank you again, i really enjoy your videos

[@TyrellKnifeworks]

Yes, but remember psi is not a measure of how much gas is coming out of the tank, just how much back pressure there is. If you have a small opening it it creates more pressure. You could actually have the valve open more and be going through more or less gas. There’s no formula for the pipe diameter but if I were to do it again, I’d go with a 2” pipe and a larger blower. Thanks for watching

[@Mucidamascusblades]

@@TyrellKnifeworks yes, that's exactly what I meant. PSI and flow rate are 2 different things and low psi and high flow rate (amount of gas coming out of the tank) can occur at the same time, if you have a large enough orifice

[@derekturner3272]

+Tyrell Knifeworks Why not add some 3/4" or 1" firebricks along the sides to reduce the inner volume and increase the insulation? Seems you can always reduce the space of your forge to get more performance. Building a smaller forge to heat up faster seems like a waste if you can just add some more lining brick.

[@TyrellKnifeworks]

Yeah I could but, 1) I love building forges, 2) I want a longer ribbon burner because with the length of the forge, there are cold spots at each opening. It's fine but it might as well be a 14" forge instead of an 18". The new one will be 18" with a 12" burner. Thanks for watching, Derek.

I have a lot of hobbies in my retirement. :) So I get the sentiment about enjoying the build. I was just offering that not so obvious to everyone solution, which is, to use a Lego like strategy with sacrificial K bricks to reduce the size of the chamber based on what you need at that forging. My main forge 36" long and a dual ribbon made of 10" square steel tube, so I typically only use the first 6-10" unless I'm making a long tool or a sword(which I've never gotten around to making, but was the reason for the long forge design).

Um this maybe dumb but could you do a video on controlling a ribbon burner? How to get it hot enough to forge weld or cooler if you don’t need it as hot. Do you not adjust it? I want to make one but I don’t see videos on controlling them. Tons on making them none on controlling them.

[@TyrellKnifeworks]

I'm not sure thats enough for a whole video but I'll talk about tuning when I do my forge build in a couple months. Until then... with any forced air burner (ribbon or otherwise), you can control the gas and air separately. If you turn down the gas with the same amount of air, you'll get what's called an oxidizing flame. Lots of heat but also lots of oxidation and very little flames coming out the front. If you turn up the gas with the same amount of air, you'll have a reducing flame which isn't as hot but will burn all its oxygen and flames come out the front of the forge to get more air. If you turn up the gas and the air equally, you'll get more fuel and more air and a hotter flame. Once you've maxed out either your air or your gas pressure, then that's the top end. Make sense?

[@christopherconkright1317]

@@TyrellKnifeworks I thought i replied to this it must not have went. So you want the air gas mix even for forge welding? Like 1 psi? If i want less scale then more gas than air?

I will send you pics or video of my forge when complete. who knows maybe i will put it on youtube not how to just me doing it.

[@TyrellKnifeworks]

@@christopherconkright1317 Of course you need a hot enough flame for the forge welding, but enough gas so that you have a reducing flame is important. Too much air to gas ratio means you'll have an oxidizing flame and that's bad for forge welding. The best way to measure it is how much flame you have shooting out the front of your forge. When forge welding, get it hot enough but have at least 6" of dragon's breath, if that makes sense. Note, On a venturi burner, you always have a lot more dragons breath because there the gas/air doesn't mix as well before it hits the flame, thus the gas hits the outside air and combusts.

[@stephenborders4654]

The easiest way to know what your true working pressure is would be to put a gauge between the needle valve and the orifice. Still, a flow meter is more accurate.

[@TyrellKnifeworks]

For a ribbon burner, that will usually read zero. There's not enough back pressure to make the gauge read anything because the orifice is large enough to let all the gas through. I had one there and it never registered anything so I took it off. The flow meter from the tank is the only accurate measure.

[@Enigma-Sapiens]

I wonder if you could just make it all out of steel? Just use a thicker plate on the bottom.

[@TyrellKnifeworks]

Yes, exactly. In speaking with a viewer about why his gauge (after the shutoff) wasn't reading at all, we talking about the lack of back pressure against the gauge. Then really started trying to compare. I'm not sure the most optimal orifice size and how to calculate that and that's something I want to research more on. Thanks for watching, Erik.

Put a pilot light in there.

You mean in the forge? That's kind of a waste as you'd never want the gas on the all the time. It's easy to put a torch in the forge to light it.

but the metal parts will rust over time. no?

[@TyrellKnifeworks]

No, not at all. I’ve had a ribbon burner for years and there’s no spec of rust. These don’t get wet, and if they did the heat burns it off quick. Thanks for watching

I've started, like so many projects, to build some of these. I just built a waste oil burner, again untested. But I've been thinking if it was possible to combine them with enough air pressure instead of a blower? I have a 10hp 250 gallon compressor. And 3 55gal drums of oil. My burner has provisions for LP for ignition & heat up. Just pondering...

[@TyrellKnifeworks]

Sounds a bit unsafe with compressed air. The pressure would constantly change, affecting your heat.

[@a.joegevara3519]

@@TyrellKnifeworks The waste oil burner I built is a siphon design, all Stainless with ball valves on each of the 3 inputs; oil, LP and the air which has its own moisture trap and regulator. Funny, like everyone else I thought I wanted to make knives when forged in fire came out. But I learned quickly I can make more money making tools to make knives with. My few knives are one of my arts and I don't make them to sell, I gift them to family & friends. My wife looks at my welded metal sculptures and says I could sell that! Me; then I won't have one. I'm a one and done type. My boss says the same about my homemade tools, lol. I have 4 ribbon burners all welded, I just haven't done the refractory casting.

Что если вместо соломинок применить свечки из парафина и потом они выплавятся.

[@TyrellKnifeworks]

Соломинки просто вытаскиваются. Вам придется просверлить воск, прежде чем вы сможете его зажечь. Это занимает больше времени. Некоторые люди используют восковые мелки так, как вы думаете. Тем не менее, я думаю, что соломинки проще, но оба работают. Спасибо за просмотр.

Sheesh

I'm hoping "sheesh" is a good thing? Thanks for watching.

[@colbornfarms4849]

Why doesn’t anybody show a complete build you know hooking up the gas and air etc…

[@TyrellKnifeworks]

Watch my build on making a ribbon burner forge. This is just about making a burner. Thanks for watching.

[@daneverhart9020]

Video seems decent but I can't see anything really bc of the words on the screen

[@TyrellKnifeworks]

Then turn off the closed captions.

first time I have seen this type of burner. I melt iron and started with a venturi "Reil" burner that needed 30 psi (at the orifice). i added a fan to the same device with a butterfly valve to regulate air flow. time to pour was the same with 16psi. forced air is defiantly the way to go plus it has the added benefit of adjusting the A/f mixture from too rich to burn to, too lean to burn. an oxygen free (slightly fuel rich) environment is desired... right? I would suggest that the fuel be added to the airflow closer to the burner reducing the amount of A/F mixture "in process" in case of back flash.

[@erlanebabur4008]

Temperatures and running time are proportional to the type of gas and gas amount used.. no matter what burner you use .... it is physics... The burner gives you the "efficiency" of use, and the "control"... You done a pretty good so far, but I always recommend adding a "back fire" prevention arrangement, it would prevent fire to stream back at the mixing tube up to the gas cylinder if it is left unattended... or you face a "power failure" at the blower...

[@TyrellKnifeworks]

I never leave my forge unattended when running, but I get the concern. Thanks for watching
