[TheForge] On the table monday.

Chuck,
Frosty covered the "gun burner" subject already; they're also commonly called
fan burners. Really, there is a lot to be said for gun burners, I wouldn't think
of using natural gas any other way. OK, I'd also make up a hand torch using
compressed air-methane after going to all the trouble to pipe natural gas out to
the garage, who wouldn't? Then too, it would make a real spiffy fuel for a
ceramic chip brazing hearth (greed, greed, slobber, slobber). Recommending a
fuel that is famous for 87% SECONDARY flame combustion may seem a little bizarre
coming from me, but spreading the heat that way isn't likely to melt the brazing
hearth chips and grill parts either! This is just the kind of thing I meant in
2004 by "one shoe size does not fit all." Rather, "a place for everything, and
everything in its place." If you had ever seen a compressed air-natural gas
torch used for heating silver, etc., you'd not soon forget the site; very nice.

A gun burner has a blower supplying the air. Naturally aspirated means it draws
it's own. Almost all oil burners are guns though it is possible to inject oil at
a sufficient pressure to induce compustion air it isn't common at all.

On the oil burner front, the recent trend is to use an air brush as the oil
atomizer/injector. From what I hear from the pottery kiln and casters, it works
pretty well.
