Re: Radiant burner need for Trot Fox
Ted Calavan came up with another easy idea to implement Kevin's radiant burner. Simply wrap the stainless steel mesh further around the burner. If the first small screen layer of mesh is rolled tighter than the burner diameter it will hold to the burner without any stiching using stainless wire. The second larger diameter and larger screened mesh layer is also large enough to wrap all but 1/8" around the burner with mesh layer. This layer needs a bit of fiddling to get it to tent above the first layer and still grip the burner. Both Ted and I made radiant burners this way. It takes less than an hour for our first one. I expect subsequent ones would be faster. I still want to do it Kevin's way. That is I wish to fabricate one with the slots cut gradually deeper from the tip back to the gas nozzle. I also want to install the burner upside down. I expect this will not only heat the last of water in the boiler but also reduce heat stress on the burner tube when water is not covering the entire tube. The last benefit I hope exists, is to heat a super heater with the super heater on top of the upside down radiant burner. I expext this would heat well with less stress on the superheater. ~Gary - Eugene, Oregon - Original Message - From: "VR Bass" <[EMAIL PROTECTED]> To: "Multiple recipients of sslivesteam" <[EMAIL PROTECTED]> Sent: Tuesday, March 05, 2002 9:42 PM Subject: Re: Radiant burner need for Trot Fox > Someone at Diamondhead showed me a simple and apparently effective alternative > to Kevin O'Connor's thoroughly engineered solution.

Vance, Could it have been John Garret or Paul Trevaskus? They both had samples at DH I believe.

Re: Radiant burner need for Trot Fox
Someone at Diamondhead showed me a simple and apparently effective alternative to Kevin O'Connor's thoroughly engineered solution. The fellow says it works well, and while I doubt it works quite as well as Kevin's, it looked to me like it should help a lot, and it was SIMPLE. He took a length of 1/32" (or so) stainless steel wire and inserted one end into a 1/32" hole drilled into the shoulder of the burner body. Then, he made a spiral of about 1/2" diameter that ran down the length of the burner, with about the 3/16" space between the coils. I don't recall how the front end was affixed to the end of the poker, but that's about all there was to it. The stainless got very hot, radiated a good bit of heat into the gas stream, and presumably finished (most of) the combustion just as Kevin's layers of mesh would. Now, who was that? I'd like to give him proper credit, as well as keep in touch with him about further refinements. regards, -vance- Vance Bass Albuquerque, New Mexico, USA Small-scale live steam resources: http://www.nmia.com/~vrbass
Radiant burner need for Trot Fox
Well Trot Fox, You could get copper screen or aluminum screen from a craft store and try the idea out knowing that what you make now now now will burn off soon, but not before you get to test it out. Another advantage, just like the SitG article claimed, the exhaust is cooler and steam plume is better. Of course the butane burner howl is quieter as well, partly because less fuel is going into the fire per second. By the way, boiler pressure was raised just as fast or faster than before from cold boiler to steam! ~Gary - Eugene, Oregon - Original Message - From: "Landon Solomon" <[EMAIL PROTECTED]> To: "Multiple recipients of sslivesteam" <[EMAIL PROTECTED]> Sent: Tuesday, March 05, 2002 6:21 PM Subject: Re: Project Locomotive chains & gears > Holy cow!
