[TheForge] Burner "flares"?

[Rick & Kims Email]

Jerry,
Thanks for all the info you provided in your posting about burners,
etc.

One question that comes to mind about  the "jet burners"...

If it is true that they introduce substantially more air than required
for a stochiometric or neutral burn w/propane, wouldn't they create a
oxy-rich or reducing condition in the forge?

OK, that's the reason for the choke sleaves on the burners, to limit
the amount of combustion air induced.

So, w/a jet inducer burner w/a choke sleave properly adjusted for a
neutral burn, why is the flame so much hotter than the straight
burner?  Is it because the jet inducer creates more turbulance at the
venturi and the result is better mixing of the fuel and air and more
complete combustion in a smaller space?

I guess there is more than one question here.
