[TheForge] RE: burner flares

[Jerry Frost]

The taper ratio of 1:12 is for the diameter. For example a tube starting at
1" dia would taper to a 2" dia. in 12 inches.

Ideally, yes you'd taper the entire tube for a distance of 9x the throat
diameter. The throat being the narrowest diameter of the tube (truncated
cone?)

I'm in the process of building a new forge and am experimenting with a few
burner configurations. The actual burner nozzles will be built into the
forge liner from 4,000f rammable refractory. I don't anticipate a burnout in
the foreseeable future. <grin>

If it ain't forged
it ain't real.
Wrought iron is.
