So finally getting the satanite over the inswool. Was curing the first layer when I noticed my burner flare was glowing abnormally hot, to me at least. I'm all new to gas forges. I've seen people say "oh yeah theyll do that its okay" and some people say" no no that's bad. So here I am. After about a minute of burn time they start flowing pretty cherry red, I had the flare adjusted outside of the forge where it wouldn't get hot like that at all. And I've adjusted them in the forge as well, I can't really move them any deeper in the inswool because the flare just sits over the pipe and a hole is drilled and taped for a stud to hold it on.  Here's a picture of it running about 3 or 4 minutes. I would assume they would get that hot anyways because the temperature the forge gets. It makes sense that they would, but I just feel like they shouldn't be. Anybody with some more knowledge chime in?

Just use a set screw to secure the flare and it won't get stuck in the liner allowing you to move it farther back. From the pic it looks like your flare is only about 1/2" back from the chamber, that'll burn it up sooner than later. My burners aren't that far in from the shell but I don't have flares on mine either, not really.

Close up the openings on your forge unless you WANT to heat the shop. No, not closed all the way but mostly closed, you want to keep as much heat inside the forge as you can. It also looks like you have the burner aimed directly across the chamber, if so it isn't ideal. The flame is hitting perpendicular to a curved surface and breaks up into turbulence and causes more back pressure against the burners than necessary. If possible direct the burners so the flame hits the forge wall at a shallow angle, this will induce a strong vortex which will distribute the temperature more evenly and not cause a high pressure zone directly in front of the burner nozzle.

I have the back blocked off completely with some firebrick. I just need to get some more so I can cover the front. Haven't been to the store to do so. 

The way I have the burners held in place I'd have to cut everything apart redrill and weld the mounts back. I don't have a welder in the shop yet. I really need to get one. Not to mention they just banned personal projects at work. So that's kinda outta the option for awhile. I could just cut them off and take a carbide bit to the hole but then they'd more less be dangling. Rather have them securely mounted.

You can see how I have them mounted in the picture. They just barley slide in. I only left about 10-20 thousands play, also I think this housing might be a little big. 

12" diameter 22 inches long.

Thanks again frosty.  

 

Yeah, it's an easy corner to paint yourself into, even after you've built a few of anythings. I just scrapped a forge I spent a lot of time working on, I'd come up with a burner idea I just couldn't make work. Then got to tinkering with a NA ribbon burner and it works a treat so the other forge is junk.

Use an allen set screw and you should be able to get it inside the flare material or won't the flare fit in the mounts? If so. . . Boy is THAT a design mistake. BAD blacksmith go sit in a corner for 5 minutes!

Folk haven't  seemed to notice but telling me what the outside of the shell's dimensions are aren't going to help, I won't even pick up my calculator. I got too tired of doing basic arithmetic for kids so I just don't do it for anybody anymore. The volume of the chamber is the main number that determines burner numbers and it's shape the arrangement.

But yeah, it looks pretty big.

Yeah I wasn't asking you do to any math for me. I think it would just need another burner for its size. Anyways, yeah the flare won't fit inside the mount. Didn't quite think it through. I didn't think it would need too! Oh well, xD

I also have noticed the top off my burners. The brass connector that's on the propane line. Is hot to where I can't touch it. Is that normal?

Ayup, done things like that more times than I like to admit. Welcome to the club.

So, for a temporary maybe not so, work around. Cut a piece of Kaowool (or whatever) large enough to cover the burner ports, make a hole in it a little larger than the one in the forge liner. And stick it to the liner over the burner port use rigidizer or satanite or whatever to stick it on, cover it with Satanite let it set and cure it.

And there, boys and girls is your Frosty the Lucky. (if it works) work around lesson for today. Now go forth and do stuff.

I see I see, some creative thinking!  

The fuel fittings don't get hot while the burner's running do they? Being on top they will get hot as can be when you shut them off through convection. Nothing like having 2,400f or hotter air flowing up them like a chimney. If they're getting hot while propane is blowing through them something's wrong. Maybe its conducting up from the over heated flare.

When you screw up as much stuff as I have you gotta get creative to get anything to work.

Well, I ended up taking the flare off. Moving it about 2 inches back from the liner. Works great! The burner stays nice and cool. No more possible melted propane line. Man that could be real bad. Glad I caught that in time. I figured the burner needed the flare but it doesn't. So we're back in business!
