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
