In Mashiko, the noborigama are mostly fired in the front with
compressed air fuel oil burners. Only the climbing chambers are
fired off with wood.

I'm looling for a middle road to take on oil burners. Household burners
pump the oil at high pressure through small orifi to atomize the fuel for
combustion. Other types use the force of air flow, team or high speed
rotating "cups" for atomization. In natural draft burners metal plates are
often used for evaporative surfaces.
D.R. Stannard built a kiln in Alaska that used trays covered with crumbled
insulating F.B. as an evaporative surface. This was similar to the oil fire=
d
unit heaters which had a ceramic pot off which the oil was burnt.
My direction (wanting to keep away from noisey fans and pumps) is to make a
small "pot" of I.F.B. in which there's a metal cup with brick crumbs for
evaporation. the fuel gasses exit into a mixing chamber where combustion ai=
r
is injected by forced air. Sort of a super-charged pot burner.

Leach's potters book has good info on his oil burner.
If I remember correctly his was able to pivot.

They come in all different sizes. A friend had them on about a
40cube kiln he fired in Kasama.

Does anyone on the list have any experience with waste
automotive engine oil put through a household style
oil burner (as in furnace burner)?
I have about 50 gallons I can access (and more coming).
Thinning the oil would not be a problem.
Anyone?
Best,

From what I've learned the type of burner used is the "rotary cup" type. =
=3D
I
think they're a bit big for the studio size kilns we have.
The direction I'm goin' is towards a small burner with a low velocity fan
(quiet) that would work in a kiln of about 8 cuft, burn Bio-Diesel and be
quiet enough so some one 20ft away couldn't hear it.

Responding out of ignorance...
Household burners pump the oil at high pressure. They generally have a ver=
y
fine screen (off the top finer than 129mesh) to keep grit from clogging the
orifice, They're also designed for a fairly light oil.
The weight of motor oil and the crud in it would require addressing these
problems. Set-u[s I've seen fo rthis used gravity fed oil and a high
velocity fan to atomize the oil.

Dear Wayne,
You ask "Does anyone on the list have any experience with waste automotive
engine oil"
Yes, I used it once a long time ago and then reverted to light fuel oil.
The results were quite crazy. I got a lot of fluxing where it might not be
anticipated. Like a glazed bag wall. So I had a chat with the Chemistry Pro=
f
at the local tertiary campus.
Apparently detergents are incorporated in hight temperature lube oils. Thes=
e
(from memory of conversation thirty years ago) were from Metal Stearates,
usually Lithium soaps. Leaded gasoline was the popular fuel at that time an=
d
so Lead levels in combustion residues could have given cause for concerns.
Dioxins might be a concern as well.
