basher Posted December 28, 2013 Share Posted December 28, 2013 I want to make a ribbon burner using a venturi gas mixer from amal. These gas mixers are made for using with ribbon burners (of the comercial catering type I presume) and I saw a great example of a glass glory hole made using one..... unfortunately the glory hole owner was not over keen on letting me have a good close look at the burner head so I am left with a few questions regarding making up a burner head.. I would have bought a head off of the glass blower except for the fact it was scaled far too big for a smithing forge. The example I saw was a pepper pot arrangement and gave a very diffused hot QUIET flame! I have an assumption that I must match the surface area of the burner holes to the surface area of the incoming pipe , the gas mixer mates up to 1" pipe and my thoughts are that I should probably be looking for a surface area of burner holes that is greater than that.... any rules of thumb would be appreciated. All the best Owen Quote Link to comment Share on other sites More sharing options...
Dick L. Posted December 28, 2013 Share Posted December 28, 2013 Here is a post that covers one made by a member here. Post #19 has a pdf. that gives a good example of the sizing. I have a Joppa glass ceramic burner for glass work made in New Hampshire and can give you the dimensions of that as well if you'd like. Mine is a blown burner using a small squirrel cage blower.

Judson Yaggy Posted December 28, 2013 Share Posted December 28, 2013 Dave Hammer, a member here, was messing around with venturi ribbon burners some time back. Don't know what he found but he is a friendly guy, I'm sure he'd share what he knows if you ask him. Quote Link to comment Share on other sites More sharing options...
ianinsa Posted December 29, 2013 Share Posted December 29, 2013 Owen, I made my first ribbon burner from info I got from John Emerging of Gearheart, he's a bit of a guru on them basically using a bit of lipped channel ,refractory and wax crayons. I can't seem to find the thread but it's in here(ifi) :P somewhere. I don't know if it's just been dumb luck but mine have always been successful I haven't made one for a while but the only change I would make is to add a few strips of masking tape to the ''lips'' to allow for thermal movement.

yahoo2 Posted December 29, 2013 Share Posted December 29, 2013 Frosty started a topic on >ribbon burners back in 2009, the guy from pine ridge burners posted a nice cutaway photo of his ceramic burner. the only venturi style model I can think of is Dudley Giberson's (Joppa glass) Quote Link to comment Share on other sites More sharing options...
MLMartin Posted December 31, 2013 Share Posted December 31, 2013 How do people feel about the Venturi style? I have head a lot about ribbon burners and would be happy to buy one from pine ridge. But even there smallest one is pretty large at a cubic foot heating volume. I am looking at half that Quote Link to comment Share on other sites More sharing options...
windancer Posted December 31, 2013 Share Posted December 31, 2013 My ribbon burner is from Pine Ridge with one of Grant's large blower motors. After running for about 45 minutes it starts making a huge noise that sounds like a .22 going off in your ear. The forge has been parked for over a year now. Tried every option offered by others and could not locate the cause or prevent the noise. Not much fun forging when half your concentration is waiting for the explosion with your shoulders hunched :) Please don't hijack this thred with more suggestions for me to try.

BANAN Posted January 1, 2014 Share Posted January 1, 2014 The reason lies in my opinion in a fireproof material used in flare .. With prolonged use heats up like a wall oven and ignite the mixture occurs already in it, and not in the chamber of the stove. Quote Link to comment Share on other sites More sharing options...
EricJergensen Posted January 8, 2014 Share Posted January 8, 2014 Yeah, propane (& methane) have a flash temperature of about 1000 deg F. Not sure there is anything to try. Probably works better for glass, since they don't need as high a working temperature. The combustion gases cool the burner block enough for a kiln, maybe not so much a forge.

swedefiddle Posted January 8, 2014 Share Posted January 8, 2014 John Emmerling has the large write-up about the "Ribbon Burners". He is on here sometimes. Gearhart IronWerks in Gearhart, Oregon John had a large article in the NWBA "Hot Iron News" a few years back. Ribbon Burners can be Venturi or Blown. They sure work good, spreads the Hot Spot. :) :) Neil Quote Link to comment Share on other sites More sharing options...
