Matt Watson Posted December 29, 2018 Share Posted December 29, 2018 20181229_093557.mp4 20181229_093659.mp4 I had my initial gas pressure too high and now I have a needle valve at the front of the line to reduce the pressure and its probably opened 1/3 -1/2 of the way open. My pressure guage should be here Monday. Then I have a second one at the burner to control the flame at the lowest burn without back burn its barely opened and then a full on burn its probably halfway open. I know I saw somewhere that when your forge gets to temperature the flame disappears which is what mine is doing but I also noticed a greenish flame coming out of the front when I turn it down to work on a hot piece ( I only see the green if the forge is hot not when I first light it on idle like in the bottom video). The burner is a Reil design with a .025 mig tip orifice. Flare is a k26 soft brick filed in a cone shape so the mixing pipe sits snug in the top about an inch. I'm going to be making a new burner and forge soon but my main question and reason for posting this is to find out if this is the right color of blue. I know really hot burn its supposed to be light blue with a kinda white center but that's almost too hot of a burn. And just the dark blue is a little too cold. I am trying to adjust to make this as fuel efficient as possible. Hence why I'm building a new forge that will have 2" kaowool with 2" HTC 100 on top of it hopefully that way it has more than enough insulation. 20181229_093659.mp4 20181229_093659.mp4 20181229_093515.mp4 20181229_093515.mp4 20181229_093622.mp4 Quote Link to comment Share on other sites More sharing options...
Frosty Posted December 29, 2018 Share Posted December 29, 2018 NO VIDEOS! Wasted bandwidth. Still pics will show us all we need. Your video is still downloading and I'm on a fast wide band connection. Frosty The Lucky. Quote Link to comment Share on other sites More sharing options...
Mikey98118 Posted December 29, 2018 Share Posted December 29, 2018 It took a little time for the videos to load, but they show a good enough flame, considering you are chocking it. Quote Link to comment Share on other sites More sharing options...
Matt Watson Posted December 30, 2018 Author Share Posted December 30, 2018 Sorry about the videos Frosty next time I'll do pictures instead. Mikey is choking it a bad thing? And as far as good enough does that mean as far as air and fuel mixtures go I'm where I need to be but if I wanted a better flame it would have to be adjustment with the orifice placement and / or containment flame cone?

Mikey98118 Posted December 30, 2018 Share Posted December 30, 2018 It is only bad when the burner doesn't need it; most burners don't need choking most of the time. Naturally aspirated burners are self adjusting to a large extent, so that increasing the gas flow automatically increases the induced air to keep pace. Well designed burners are only choked to achieve special goals, as when ensuring a lack of scale while welding. The rest of the time a choke is only used upon shutdown, to prevent chimney effects from overheating burner parts. If a burner actually needs choking during normal operation it probably should have a larger gas orifice; and no, yours doesn't. Your burner flame is ever so slightly reducing; the very flame that most blacksmiths prefer. Quote Link to comment Share on other sites More sharing options...
