On average how much oil do you use for a typical firing? And when I say t=

Your kiln is different than anybody elses so your results vary. I am only l=

About what temperature do you reach before you begin using oil? =20

How long before you reach max temperature after you start using oil?

Thanks in advance

Jon,
Veggie oil firing is no problem. The amount of oil you need varies. We
used 30 gallons for a 70 foot Noborigama and we also used wood. You may
not need that much.
This is a great idea! Don=92t be dissuaded. Doing the right thing takes
effort but it always pays off!
It is not a mess unless you let it be a mess. It doesn=92t have to be =93bas=
ic
pollution=94 and you don=92t have to run out of oil. If you are intelligent
and plan out the amount you will need and then have some extra, you will
be fine, especially since you need an alternative heat source to start the
kiln anyway. You always have that for back up. (Wood or gas)
I am sure you have read "French Fried Pots" by Kent McLaughlin in the
December 2007 edition of CM page 32. He describes some parts of his set
up. He used 25 gallons and has a waste oil burner. He starts with propane
and then he starts introducing veggie oil at cone 012.
Do you have a burner or a drip?
I used a 50 gallon drum and had 1/2" black pipe to deliver the oil. You
need a large enough pipe for the oil to move or you have to heat it to
make it more fluid. (Described in this article:

etableoil.aspx
Kent is teaching a class right now at Penland (8 weeks) and is doing this
very thing. You may be able to contact the class or go for a visit?
Hope it helps,

Park's system works so you can't beat that but the technology seems ancient.
I've been looling for more efficient systems online-
A key term I got from a US potter workin in Japan is "rotary cup burner " where rotary-cup burners are apparently the standard.
There was an article in Ceramics Monthly a few months back. The illustration of the burner shown was a Rotary-cup type but nothing was said about the burner or its source. This site is good for basic info. What he says about rotary-cup's preferences fo fuel viscosity (thicker) and not being impacted by impurities in the fuel makes them sound like the burner for waste oil
(Check out http://www.steamesteem.com/ for good background info- Look at menu items
Fuel atomizing methodsFuel pressure jet Intenal mix External mix Rotary cup Low ressure air Blue flame)
{This is a wild and crazy pyro-guy site http://www.backyardmetalcasting.com/guest_willsburner.html
who gives a link to this company's site- http://www.hed.com/blueflame/index.html
I got lost and found this...
