Can anyone give me some information about using oil burners on small down
draft kilns? I live out in the boonies now and the cost of propane is really
expensive in this area (because of the road conditions out to my place and
the distance into town). Any information would be greatly appreciated.

I have a small oil-fired salt kiln. I power the burner with a shop vac and
burn diesel. Oil burners are extraordinarily powerful, compared to most
gas burners, and you may only need one, unless you have trouble
distributing the heat from one across the face of your load. And though my
kiln is so small I just buy a few gallons of road-tax diesel when I'm
getting ready to fire, you can get fuel delivered at a much lower price for
off-road use (as farmers do for their tractors.
I built the burner from plans in a nifty little book by Andrew Holden,
called _The Self-Reliant Potter_ but there are several designs and they all
work pretty well, though you'll need to play around with them, probably,
before they are tuned just right. The design I built, from pipe fittings,
takes air from the blower down a 2" pipe to a pipe cap with a small hole in
its face. The oil is fed by gravity through a small pipe and is released
just before the hole in the cap, so that it's broken up by the turbulence
and speed of the air going through the hole and sprayed in a fine mist into
the firebox.
Very practical, in my opinion, and less troublesome than propane, in some
ways. You never have the tank freeze, though if you live in a harsh
climate and your oil tank is outside, you may need to use one of those
immersion heaters to keep the oil fluid enough to feed.

Vince, An alternative for those rich kiln owners in Japan might be
"Swirlermizer" burners made in England. They used to be sold by a company
called "autocombustion" . The last I heard was that they had been taken
over by another company. Lots of potters in the UK use the small versions
but they do make enormous ones as well. They work very well. I am sure
someone in the UK that is on the list will be able to supply up to date
information. By the way Walter Hyleck not far from you in Berea Kentucky
has a set of them. I have a set which I am hoping to use again in the near
future.

I found this address which Bob Briscoe referred me to;

I have never bought their burners but thought I would pass on the
information,

Clarkson's burner system was designed to work in a kiln which had =

Anne and others interested.......
Don't know about burning waste cooking oil - but know it can be
home-converted to deisel which burns great ;o)
Those who are interested in building their own kilns or oil burning
might want to check out this site. These kilns are usually for burning
out wax from castings or involve crucibles for melting metals and so
wouldn't have the temp refinements necessary for ceramics (I think) but
there are some great ideas here. Bruce is a real master and always
happy to offer help on any type of art endeavor.

In the interest of a safe environment, and to prevent some unexpected
problems. I would recommend anyone that is going to use new or waste oil
burners check out the following link to the National Park Service
EnviroFacts bulletin. It contains a check list. I would not consider it
inclusive. One statement in the bulletin is as follows: Generators of used
oil must manage it in accordance with 40CFR part 279. State used oil
regulations may be more stringent then the federal standards. State
requirements must be reviewed to thoroughly assess compliance status. Some
states do regulate used oil as hazardous waste.

cheers to that, man. I am trying to get, amongst other things, a
wood kiln put together here at auburn, and I am interested in a lot
of the stuff you are talking about. our construction is a fair ways
off, as of yet, but we also have a pretty big supply of saw dust and
pallet boards to burn. I am curious about the oil firing, mostly
because I am curious... I don't have a whole lot of info as of yet,
but Lowell Baker, who teaches at U of A, has done a bit of work about
sawdust burners. I am hoping to contact him once we get a bit
further with our wood kiln and some other projects. I am interested
to see what you come up with, too.
Keep us posted,
jon

I guess I should have told the whole story before asking questions. =
Thought maybe I wouldn't have to.
I am able to obtain around 150 gallons of oil per year from a friend in =
the business of filtering oil for resturants.
The term " around " means just that.
What this has set in motion is a thinking that I can fire with oil, or =
whatever else to peak temp ( ^10).
To further add fuel to this fire. I can obtain sawdust from a local =
cabinet shop. 4 or 5, 32 gallon garbage
cans full a month. I have another friend whom is building me a burner =
for that. With these two alone I can save countless dollars=20
on my propane bill.=20
But wait there is more.
The friend that is building the burner also gave me some fire bricks he =
had to move when he sold his house. With these I am=20
reconstructing my kiln to add a fire box so I can start with wood scraps =
I can collect from work. Seems they=20
throw away about a trailer load (tractor trailer that is) a month of =
broken skids and skid tops. I am only
getting the tops. Most are 1"x4"x23" and 54".=20
So if the propane runs out I can finish with wood then reach peak temp =
with oil and or sawdust.
Sounds like a lot of collecting...well it ain't. Its really a lot of =
savings. And it stays in my pocket.
All the resources are willing to help any way they can. What this means =
is if I don't need it I=20
don't have to go get it. They can continue on, business as usual. I =
just make=20
a phone call and they will start saving for me again.
Its good to have friends.

Actually Lowell Baker has done a lot of work with the sawdust injection
burner! I had the opportunity to hear him speak at NCECA a few years
ago...Wow!! What a learned man! I am actually in the process of building a
sawdust injection burner for my kiln following his diagrams. He also had
some information on sawdust injection firing in Nils Lou's book on firing.
As with anything, I know that following his diagrams will only get me so
far, and I will have to adjust and tune the system to fit my kiln and style
of firing. With sawdust injection, the norm is to fire to red heat with
another fuel source, like propane, and then change to sawdust injection to
fire to maturity.
take care,
Pat in SD- where we just got dumped with 4-5 inches of snow yesterday, a
full week AFTER the first day of spring! UGH...
