I have both a one brick forge and a coffee can forge. I fire them with two Rothenberger Turboprop burners like this

but I can't even get near forge welding heat.
I burn propane.
I know that you CAN get welding heath (and far beyond) with venturi propane burners.
So does anybody have some tip for me?
 
It looks like that burner might not be putting out enough btu's to reach a welding heat in your forge. Build yourself one of the venturi type burners and hook it up to a BBQ grill propane tank. That should get things hot enough.

Here the data for the burner:
Turboprop 15 propane burner.
g/h 180 @ 2 bar
kWh - kcal - BTU: 2,30 - 1980 - 7855
Length 195 mm
Ø 15 mm
Weight 110 g

I could upgrade to the Turboprop 24
g/h 450 @ 2 bar
kWh - kcal - BTU 5,75 - 4950 - 19640
Length 270 mm
Ø 24 mm
Weight 320 g

that is over twice as powerful, but with the 15 I'm already experiencing bottle freezing problems :(

The small forge caviy is about 4" diam x 6 inches long, while the one-brick is about 10" long.

Do you think the 15 is enough?
Which is the optimal or anyway minimum burner BTU output per chamber volume unit?
 
Thanks but I didn't make the tutorial. I can't remember how I found it, maybe off one of the links on Ron Reil's own website (which is kind of confusing :confused: I got lost a few times ;) )
