prof Posted September 16, 2008 Share Posted September 16, 2008 I have a double burner gas forge, that after it has been going for awhile one side seem to cut back and not put out the same as the other. There is also a notice able difference in the sound. Does anyone have any ideas what may be the problem. When it starts this i can turn it done for a second then back up and it will run ok for awhile then starts cutting back again????? Quote Link to comment Share on other sites More sharing options...
NateDJ Posted September 16, 2008 Share Posted September 16, 2008 sounds like it may be freezing up, is the nozzle really cold? Could it have trash in the line causing it to partially stop up? Is the nozzle getting really hot, this could cause the tip to constrict? Just some ideas to start checking. Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted September 16, 2008 Share Posted September 16, 2008 First is this a BLOWN or ASPIRATED burner? (I have a vehicle that loses power I won't tell you if it's a diesel or a gas engine can you tell me what is wrong...) If it's run off the same tank then freezing is not a problem as only one has the problem. However as a forge/burner warms up it changes it's burn slightly and this can show up slight problems in it's construction. I have a double aspirated burner forge that gets the *exact* same symptoms when the adjustment of the orifice straight down the tube has been knocked slighty out of true when taking it on the road a lot---I try to keep the adjustment set screw allen wrench in my truck so I can't leave it at home... (also check for crud in the orifice, teflon tape is bad for this) Works fine when starting and gets wonky at heat. IFF you have an aspirated burner that is what I would check first. If that's ok you may want to see if you just need to adjust the choke to a different setting when hot. You're doing good in that you pay attention to the sound the forge makes, that's one way of tuning it! Quote Link to comment Share on other sites More sharing options...
Golden_eagle Posted September 16, 2008 Share Posted September 16, 2008 Check for burrs inside the tip (the hole in the $0.50 pipe across the top) if its a aspirated burner. I had similar problem, Quote Link to comment Share on other sites More sharing options...
divermike Posted September 16, 2008 Share Posted September 16, 2008 If it is an atmospheric like mine, something as simple as a spider web in the throat or orifice can lead to this issue. I was recently very pleased when I disassembled mine and cleaned it completely. It had slowly diminished in it's capacity, until it was clear something was wrong. After cleaning, wow, it is too hot to handle. Quote Link to comment Share on other sites More sharing options...
