Here are some pics I took just now. I also ran a drill bit through each nozzlette and made sure there is nothing bouncing around in the inducer box that could plug holes. I also ran some weld wire through the welding tip to make sure it was clear too, just to cover the bases. The first pic shows the forge running at full throttle, which doesnt seem hot enough with almost no visible flames. I've also attached a short video of the burner running at *very* low pressure, it was my first test run of the burner after it was cast and baked. 20200831_203356.mp4

Hi Frosty, I'm from north-central BC in Canada, so not likely anyone in visiting range . As for your questions, after melting out the crayons I used a drill bit by hand and reamed each hole until i felt the bit bottom out on the back of the metal inducer block, so the holes themselves should be clear. I then did this again after coating the face with TIC-100 to make sure that none of that had dripped into the holes creating a plug. The block is held in by 4 set screws though, so its very easy to remove and confirm. I'll do that later today. For my set up I have a Hi-PSI regulator running off a 100lb propane tank, with a 3/8ths line run to the forge, which tapers down to the MIG tip that is used as the jet in the T inducer. As I said, I copied your final dimensions exactly as far as I know. Even when running full open on the regulator, the best I get is a light orange heat, not quite yellow. Is this typical of propane or should I be able to do better than that? I'll post a bunch of pics, perhaps that will help. Also, this issue is happening as full open, so there is no more pressure fuel i can add. When it is first warming up, the flames lift off the block at full throttle, but once the forge is up to heat, they are maybe 1 inch blue flames sitting nicely on the block at full throttle. Thanks again!

Hello all, First time poster with a question. I wanted to switch from my dirty coal forge to propane, so I made a ribbon burner following Frosty's NA Ribbon burner build, using the same dimensions and everything. The forge heats up fine and runs fine for the first hour. After about an hour is starts backfiring, or detonating inside the mixing chamber. I didn't put any baffling inside the black itself as it sounded like it wasnt necessary from Frosty's write up. I suspect detonation is result of the ribbon burner nozlettes heating up themselves as can be seen in the attached photo. It's odd that only some of them heat up though. Any guesses as to what I did wrong, or how I can fix this? My forge is a 30lb propane tank with 2" kaowool coated with MIzzou and ITC-100. The burner itself is a block of Mizzou with a coating of ITC-100 on the face. Would switching to forced air once it is up and running help mitigate this issue? Thanks in advance!
