Yep, it makes sense, hence why we are getting so much heat being transferred upward on the burners. I'll need to source the refractory to make the nozzles and work on that before doing any other adjustments. Might take a while. Any suggestions on what to use? I'll dig into the refractory topic as well. Much obliged! Will likely need you again before this over.

Pictures are easier to explain it....

It's burning best at 6-7 psi. The burners extend 1/8" or less past the liner. The burner port is 1-1/2 black iron pipe welded to the case and tapped for 4 bolts to hold the burner. The gap between the holder and the burner tube is blocked with blanket. So for the nozzles would you just roll up or build up the ceramic blanket with rigidizer with the 1:12 flare or do we need to start over with the main blanket to do that. Sorry, newbies here. And we will fine sand and de-bur the nozzles to get it tuned up from here. One more, how do we know if we get it too lean?

I leak checked the lines and all is good now. Here are the other pictures. Sorry my phone isn't the greatest for pics. We get a high flame creep oit of the front, too big of an opening? Of these aren't any better I'll get someone else to take the pics instead of wasting time. Appreciate the help!

Hello, new here and we just finished building our first gas forge with two 3/4" T burners. Thanks, for the design Frosty! The directions were easy to follow and we took about 1/16" off the tips each time to get them burning. We need help with tuning the burners. We do not have nozzles on them yet as we are having a hard time locating the thread protectors. We do have good hot flame and loud roar from both. The front seems to be running rich but we don't have the experience of reading the colors and patterns. I can tell you that we have alot of propane smell from the forward burner when it is burning and it is not as hot as the rear burner. Appreciate any help with diagnosing these flames as rich or lean.
