Hello everyone!, I am new to this forum and looking forward to interesting discussions 

I would like to build my own gas ribbon burner forge. During the planning phase, I am unsure about the correct angle of the burner.
Could you help me to align it properly?


Technical specifications:
Forge size:
See side section. Length: 516 mm
Burner size:
The burner head is made of refractory concrete. The dimensions of the refractory concrete are
L = 300 mm, W = 80 mm, H = 25 mm.
There are 45 M8 drill holes on this surface.


Thank you very much for your help! 


Kind regards The SpaceForgeProject

The answer is that, with ribbon burners, positioning is less critical than with any other kind. The position you propose will work just fine, as will many others. So, what is the "best" position with ribbon burners? Mostly it is simply a matter of preference.

These days "refractory concrete" is a very loose term. However, most refractories do not make a good choice for use in ribbon burners, for two reasons. To begin with, ribbon burners most withstand severe thermal cycling without cracking. The second problem is heat gain in its internal mixing chamber, leading to early combustion. Kast-O-lite 30 has been the refractory of choice for years because it is formulated to resist thermal cracking and do a very good job of insulating; it is also rated to 3000 F.
