Frosty

Naturally Aspirated Ribbon Burner. Photo heavy.

Recommended Posts

Decided to play with my narb today.  Plugged 3 holes and it worked very well.   So I insulated the forge and rigidized it.   Waiting for kastolite to show up and I’ll get it finished up.  Had 21 holes and 19 after plugging 3.  Tried plugging 2 and it did burp a few times.  With 3 plugged it was stable down to 5psi

Looking good. Looks to be running a bit rich maybe a LITTLE more trimming is called for, no good reason to generate more CO than necessary. With the burner mounted horizontally any chimney effect will be very  minimal and ribbon burners don't make a lot to begin with even mounted vertically. You can attach the rubber propane hose directly to the 90 fitting on the burner without worry of over heating and put the valve at the other end of the hose. 

I've tried the 1/4 turn ball valves I use at both ends of the fuel circuit and it makes so little difference as to be none. 

Altering the propane circuit isn't so important, you have it well thought out and I see little chance of problems as is. However I do recommend you do a little fine tuning and get your flame closer to neutral, Carbon Monoxide is bad stuff, it takes something like 80x as long to flush out of your blood as it takes to replace O2 molecules bonded to your hemoglobin. Extreme poisoning may require a stay in a hyperbaric chamber.

Even if your shop is well ventilated, CO can effect you and folk around you. Sorry to go on but I get jumpy when I see such a rich flame, I don't have so many friends I can afford to lose one without saying something in prevention.

Lol that’s a typo.  18 after plugging 3.   

I will trim a little bit at a time till it neutrals out.   

I dout co can build up in my shop with 3 walls but why chance it. 

Flame is more blue in person but the camera always changes the color   

For some reason you can’t even see all the flames in the pic

A TYPO!?!:o <gasp> I keep hearing about typos but . . . I'm no longer much embarrassed by missing a key stroke but they make great straight lines for a born wise guy like me. 

You might consider opening one of the outlets you've plugged but I'm up in the air on that, I really HATE changing more than one thing at a time trouble shooting a problem. I still think the inducer needs tuning but opening the flow a LITTLE will reduce back pressure and shorten the flames.

Still that'd be two changes and. . . :unsure:

I don't just look at flame color. I look for the degree of transparency in specific flame envelopes and your flames are opaque light blue in the outer envelope which says "Rich" to me. The outer envelope should be nearly transparent dark blue, some guys are hitting invisible or non existent outer envelopes which is running to the "lean" side. My personal preference is SLIGHTLY reducing to minimize scale formation in the forge

I haven’t plugged the holes permanently yet.  Just stuck some chunks of 1/4” round in the holes for the test.   I do believe your right about trimming the mig tip as it is a bit long/past center slightly.   I’ll play with the tip and get it running a little more closer to neutral before I come back to the nozzles holes.  

Thank you for your input.
