Turkey fryer forge burner.

I have figured out a very easy propane forge burner. I have a thread started over on the bladesmithsforum.com here is a link to it.

https://www.bladesmithsforum.com/index.php?/topic/36681-very-simple-beginners-propane-forge/

Here is the most recent one i finished. I was going to do some extensive testing with it but i ended up selling it. But i will build another just because it works so well.5ac03125a7f61_avoid_a_house_fire_when_cooking_with_a_turkey_fryer_this_thanksgiving.thumb.jpg.e48e664b78aff2f8cbcedb3ac37e009d(1).jpg.4665903fa03397b4f3fdcc5ff09093ba.jpg5ac031423f8bb_20180112_114224.thumb.jpg.bf5bc198524acee16a9345ab1ee62d63(1).jpg.c3850a3cfeff7c9937bf1080563624cf.jpg

this last picture is a bar 1/2 inch thick 1 1/2 inches wide.

I was actually thinking about doing this with the burners from my Camp Chef grill.  It has three burners that operate on a Venturi.  Each burner produces 30,000 BTU.  In trying t9 figure out how I would protect the burner with refractory I decided it would just be easier to make a NARB.  Still an interesting idea.

Use it to drive the NARB. Or you could put it in an updraft position and use hard refractory in the liner to form a nozzle flare. That should protect the inducer well enough. Hmmmm?

It is to one Venturi...it is three small ones (one for each burner).  I was think8ng I could put thin rods into each nozzlette on the burner, apply castable, and then yank them when it dries.  My main problem is that the burners are round and I can’t visualize how I would insulate the center of them.

Seriously, though, I am somewhat dead set on building your NARB design ...or paying you to make me one and ship it to the lower 48..<wink wink>

Okay, what you're calling a "venturi" is a linear inducer so we don't confuse each other more than necessary or fun. The burner itself is a multiple outlet burner, so is the NARB. Try this on for size. Stick a crayon on each nozzle on your burner burner and cover them with Kast-O-Lite 30. When set remove the crayons. Viola, forge burner!

I wouldn't cast the entire existing burner ring in Kastolite just enough to provide a good heat shield long enough to work in a forge. I think you'd only need some of the existing burner ring set in the refractory, maybe use modeling clay to fill around it like the bottom of the mold "flask."

I REALLY don't want to start selling NARBs. Once it started it'd be like a day job. <shudder>

Got it.  Venturi is the process...inducer is the port at the end of a tube?

 

Either way, I was thinking I could drill holes in the side of the forge for each outlet nozzle on the burner so it can be mounted outside the forge.  Use the crayons, etc...

But I was concerned that the relatively short flames it produces wouldn’t be able to make their way past the 2” of Kaowool and the 1/2” of castable.  If I ditch the wool I feel like I’d have an inefficient gas hog.

It’s still an idea that grabs my attention every time I start up that grill and the burners sound like a jet with pure blue flames.  In open air they get the 1/4” grill grates glowing red.

This is the burner (comes with 3 on a grill):

It just seems like the work required to implement this would be better spent on a NARB.
