I've seen something like this done in a furnace used to melt iron for casting. It was very impressive, kind of like someone projecting lightning from their hand! Viewed from a distance, when handled by professionals, it was awesome. Lit up the night sky like a carbon arc light!

I wouldn't want to be anywhere in the neighborhood of someone doing the same in a kiln. You can probably reach cone 15 or 20 almost instantaneously with a rig like that.

This is quite common in industry and has been for some time.

The main reason is to eliminate the vast heat wasted in heating the appro=
x.
80% Nitrogen that air contains. To control this sealed port burners are
used.

When combined with pulse firing, this approach can result in very high
heating efficiencies.

One thing to keep in mind is that using O2 in combustion situations is no=
t
something to be taken lightly. This introduces numerous technical issues=

that could result in some increased hazards to those who are not pretty
well versed in combustion theory and equipment design. If you elect to
try this stuff...... do your homework first so that you don't "re-invent
the wheel"..... and so that you don't end up hurting yourself or others.

Best,
