Try hybridizing used veggie oil with wood!

In olsen he shows a tamba(?) kiln set up to burn oil. The burner looks
like a centripital blower fith a rubber fuel hose entering on the axis.
It's a rotary cup buner
Lars at http://www.steamesteem.com/
says
"The *rotary cup* is driven at high speed (about 5000 RPM) by an electric
motor via a heavy-duty belt drive. The fuel oil flows at low pressure into
the conical spinning cup where it distributes uniformly on the inner
surface and throws off the cup rim as a very fine oil film. A primary air
fan discharges the primary air concentrically around the cup, strikes the
oil film at high velocity and atomizing it into tiny droplets. The rotary
cup burner finds considerable use on packaged shell type boilers. These
burners have good turn down ratio and they are rather insensitive to
pollutants in the fuel oil.
A *rotary cup burner*requires a certain viscosity to perform best. It works
very well on HFO, Heavy Fuel Oil, but it doesn't give full effect on DO,
Diesel Oil."
But the trick is finding a US vendor or another way to buy one from japan

when I was Program Director at the Campbell Folk School in Brasstown, NC
back in the late 80s, I contacted Tracy Dotson to plan such a kiln. It =3D
was
built by an Elderhostel Class over a one week plus weekend period by =3D
those
over 65'ers. We made pots and fired them using bottled gas to preheat =3D
the
kiln overnight and then in a 17 hour firing, we lfed donated wood to =3D
make
the firing complete. It was a successful experince and the glazes we =3D
used
turned out beautifully as well. I don't recall any ash at that time as =3D
it
was the first firing. I believe it is still being used by classes at the
school. We designed a two chambered kiln so that the second chamber =3D
could be
used for bisque during the Cone 13 firing in the front chamber.=3D20
