Forge Build pt 1 Ribbon Burner

This is the beginning of building a forced air propane forge. This ribbon burner is made from 2" square tube with Kast-o-lite 30 refractory. Some cut up fiberglass was added for added strength.

Absolutely awesome build! Pulling those straws out looks like the most satisfying thing in the world. I may have to build one of these when the time comes for a new forge.

[@johnjude2685]

Great video, I built mine,on top of the straw I placed a small nail to cover them Thanks

[@bjorn980]

Thank you, for that great documentation Sir!

[@charruauno386]

Thank you for showing, very nice work, and have a good day.

[@kaelstandeven9236]

That looks awesome! What are the dimensions of the burner compared to the forge interior?

[@camillesennegon]

Nice build ! Looks good, ribbon burners works really well, i built a forge with one of them, it's a monster

[@Shadowfusiondesigns]

what did you spray on it to get everything to come out

[@marciofernandobarci]

very nice = thanks - music is top

[@WildmanTech]

I use butter flavored mold-release agent from the dollar store.

[@user-zx7tg4ph5r]

I wonder if purchasing IFB insulating Fire Brick and drilling holes through them would work? Then strapping it onto the burner housing. What do you think?

[@thorneworks]

i don't think IFB will hold up. but my be worth a shot. will still need to cement it into a manifold or some sort though.

[@hyperhektor7733]

is there any rough forulma for finding the optimal holenumbe4r & diameter for a given input pipe and pressure ?

[@gabrielevans-riverin795]

Amout of surface for the gas intake (top pipe )= sum of the surface of the holes of the straws

[@docesam]

But the metal parts will rust over time.

[@theringoffire67]

How long did you cut the straws? What is the height of the box? Thanks!

[@texasironforge.4913]

So I have a question how many of you think it would be a good idea to use a soft high temp insulated fire brick instead of castable refractory. I hear it's pretty easy to cut and I bet it would be pretty easy to draw small little holes I'm thinking about experimenting and trying that out

[@althesmith]

How far up is that baffle plate welded, and is the peak at the bottom or at the top (curving towards or away from the inlet?)

[@thorneworks]

The peak of the baffle is at the top/inlet side.

[@evaderknives]

Nice build, I was trying to figure how you would use wood on a burner, then it all made sense, haha... Was that fiberglass or koa wool you mixed in??

[@thorneworks]

Thanks. It was fiberglass I added in there. Just to add a bit more strength.

[@clagace5121]

Did you use a 9/16 or 5/8 cement spreader?

[@thorneworks]

A keen eye would have known that was a 9/16 cement spreader.

[@ShopperPlug]

Can't stainless steel be used for both the chamber and nozzles? Are you using ceramic fibers into the mortar mix? What kind of spray did u use?

[@thorneworks]

Stainless wont hold up very long, ...it needs to be refractory. The fibers adder were glass fiber just to help give a bit more strength. And the spay I used was an industrial mold release.

[@ShopperPlug]

@@thorneworks can stainless withstand for pizza oven temperatures? I was planning to use all stainless for a pizza oven using this ribbon burner concept. Pizza ovens does not go above 1,000 F.

[@thorneworks]

@@ShopperPlug I would think for a pizza oven SS would be fine. Although a forced air ribbon burner is likely a bit of overkill for such an oven. A naturally aspirated system would work fine...a SS tube with a series of orifices should suffice.

[@adamvacancy8407]

Was that mold release spray you applied before packing in the kol30?

[@thorneworks]

Yes it was mold release.

[@lucadascenzi2468]

Super lavoro complimenti!!!!! This Song name?

[@thorneworks]

Song name is Westward. but I don't know by who or where I got it. It was a copyright free tune.

[@thorneworks]

Now I remember. it was from Ampletunes . ampletunes.com/downloads

[@tmarr535]

what size are the straws ? i hope that isnt a dumb question

[@Giganfan2k1]

No dumb questions. He used "regular" sized straws as far as I can tell. The diameter can really be any size. The real question is what is their combined "diameters". To get your idea size straw you need to know your what fuel to air flow ratio you have. Then figure out the optimal diameter of that fuel/air ratio. Lets say it is half an inch diameter. If each straw "normal" straw was 1/16th of an inch you would need 8 evenly spaced. *OR* lets say you used those thin coffee straws and their diameter was 1/100th of an inch. You would need fifty; evenly spaced. All these numbers are for demonstrations. When you are ready to make your rig you will get all your numbers from the parts you are using. There really isn't a one size fits all. Last, don't over stress yourself. If you get it wrong the first time you just won't have the most efficient burn.

[@thorneworks]

Yes they were regular size straws, not those big jumbo ones. I do remember running the calculations on cross sectional area of the straws and piping....as Sum Arbor mentioned. But I can't remember if I actually tried to make it match or just did the calcs to see where it was. Either way it seems to work well.

[@nicholaslambert3586]

What are the names of the songs that were played?

[@thorneworks]

first one is called Westward and the second is called Gold Rush. Sorry I don't know where I got them. They came off one of the royalty free music sites.

[@thorneworks]

I found where I got them from...it was from ampletunes. ampletunes.com/downloads

[@brianadams1907]

Thank you Sir... I was wondering about the music while admiring your Craftsmanship.

[@texasironforge.4913]

So I have a question if you had a 30 inch ribbon burner would you only use 1 2" inch nipple for the top or would you apply 2 or 3 of them seeing its a big ribbon burner??? please get back to me. thanks

[@thorneworks]

I think you would want to use two of that size pipe nipple, and upsize the piping and blower upstream ....or use two blowers and 2" piping to each. I used 1-1/2 on this one and it works good for a burner about 12" long.

[@texasironforge.4913]

@@thorneworks okay thank you very much yeah I think I'm going to go with two inlets because it is a pretty big ribbon burner
