Oops, should be good now.

So, weather was cold so didn't get to spend much time in the shop. I finally managed to do the checks and the modification mentioned by Frosty in this thread and I am happy to report that the burners work fine now. However, it seems I am having a couple of different issues right now: first, the flames are shooting up from the burner openings. Second, and definetely more importantly, my CO alarm is beeping like crazy, with the old forge. Up to 150ppm but most of the time it stays around 50-60ppm. My "shop" is a half container and while the air circulation is not perfect, I kept the doors open when I run the forge and the CO detector was just above the forge and it has never registered any values above 5-10ppm. Not sure why the change now. I have already moved the forge (conviently on caster wheels) right at the entrance and I am looking at ways to move it outside while it is running, but need to keep it protected from rain. Any suggestions for a ventilation system would be welcome. (the glow is from the fire bricks. While I did remove some firewool from around the hole opening and covered the exposed one with refractory cement, the fire bricks still have the original diameter, so the flame is basically hitting a part of it before entering the open forge space -> /_ _\ basically the _ parts ) Video 1 The flame shooting up from the openings. Also, the back burner seems to have a different flame color. Any ideas why? Video 2

The forum plans look like they are the same as what I have used. I don't have a flare at the end right now. I did have a 3/4 to 1in fitting in the previous forge and I also tried it in this one, without success. Also, I forgot to mention that the burners are doing the same thing even outside of the forge, during testing, with or without flares. I will check if any teflon tape pieces are causing the issue and see if moving up the burner tip solves this.

Thanks for the replies both and sorry for the late response, life in the way etc. Frosty I followed your plan, which I found here. The tube is 150mm, which is a hair under 6in. The construction of the forger is 2mm steel shell, then 2in or so of kaowool and 1in refractory bricks. The nozzle is just barely inside the refractory brick. Does that mean I have to pull them up? Wouldn't that blow fire right on the kaowool, which would be a terrible health hazard? Also, the channels where the tubes are in, are narrower than in the previous forge. Would that perhaps reduce the airflow? Although, now that I think of it, there are two huge openings, larger than in the previous forge front and back... Mikey Hmm, I don't think there are any obstructions, but this is a good point. I will check this when I am next in the shop.

Hi all, I was hoping I could get some help with my new forge. As you can see in the videos, I am having various issues with the burners not lighting up, sputtering and flaming out. I can run one of them on a very low pressure, but not both of them. The weird thing is that the burners were running more or less fine in my old cylindrical forge (standard 11kg propage gas tank) and I recently decided to build a newer one, because the kaowool insulation was starting to show and it was a health hazard. I also changed the mig tips, but used the same type, 0.8mm. I use the standard Frosty T burner, with 3/4" pipes. I have uploaded some videos on youtube: https://youtu.be/bfH0cJ-rJ8A https://youtu.be/JadlPS0j02s https://youtu.be/9wS_3ByUAJs https://youtu.be/Gf95-lzm_Iw https://youtu.be/Iw4BTFeITaQ I am not sure exactly what is wrong, but I am hoping that your collective expertise will help me out. If there any info about the forge please let me know and I will reply. Thanks in advance!
