I don’t know how finicky all the specifics of the burner construction are, so I’ve decided to err on the side of caution and ask for advice from an experienced community. Now that I’ve gotten to the point of building the burner I have a bunch of questions. I’ve attached a photo of the body of my forge so far, a photo of the forge that I’m basing my design off, and the label on the blower of said forge.
What should the internal diameters of all the pipes be? Of the mixing chamber? How much does it matter?
Are the 90 degree bends in the gas pipes and the pipes from the blower (see the photo of the MassArt forge) important?
The burner on the MassArt forge goes straight down at a tangent to the inside curve of the forge, but I’ve heard that having it go in horizontally at a tangent to the inside curve might be better. Thoughts?
I’m content to fabricate the system out of pipe and fittings when I can, but what actual hardware do I need? I noticed what looked like venturi holes on the pipes leading from the gas to the mixing chamber.
What are the specifications of an appropriate blower? And where can I get said blower? I’ve looked at MSC and Grainger and couldn’t find anything that looked appropriate.
I know that the pipes that convey the gas into the mixing chamber penetrate a few inches into the mixing chamber. Is the exact distance they penetrate important? Is the aperture size important?
Is the fact that the burner enters the forge at 3 ports important? Helpful? Unnecessary? Would one entry point be better? worse? doesn't matter?
Is there anything I’m forgetting?
Thanks a lot in advance.
