Is there anyone running their kiln with bio-fuel.
The price of electricity is about to rocket here (56-75% increase this =
year), gas is already expensive & many potters are firing with paraffin =
(gasoline). We have been experimenting with veggie oil, but this is =
proving hard to come by (believe it or not - someone is on the =
bandwagon). Fuel prices are also soaring, so what next. Discussing =
this with a local kiln builder, our next try is bio-fuel.
The kiln we will be building is a large fibre kiln (around 40sq ft), but =
he will experiment with a smaller one first.
All help will be appreciated

direct burning of veggie oil that has not had the glycerin removed is
supposed to cause nasty pollutants to be released into the
atmosphere, believe it or not. look up acrolein:
http://en.wikipedia.org/wiki/Acrolein
It was once used as a chemical warfare agent, and is an extremely
likely carcinogen.
Acolein pollution is also a big problem with people burning straight
unmodified vegetable oil in their diesel engines. People look at it
as free fuel, but there are pollution costs that people don't care to
acknowledge. since it comes from nature, ergo it must not be bad for
you. One word for you - TANSTAAFL! -for those of you who don't
read Heinlein, "There ain't no such thing as a free lunch!"

Wood is one of the best bio fuels, especially if you raise the wood
for fuel. You leave 2/3rds of the carbon a tree takes out of the air
in the woods as roots, leaves etc.

Bio fuel- (Wikipedia says)- "broadly defined as solid, liquid, or gas fuel consisting of, or derived from recently dead biological material, most commonly plants. This distinguishes it from fossil fuel, which is derived from long dead biological material."
In that case- yes- I use wood. :)
If you mean- waste bio-produced fuel- then yes- I use waste wood. With a 40.5" (4.5 bricks at 9" each) firebox, just cut 40x48" pallets and throw them in. They provide crazy heat quickly.
If you mean liquid biofuel- well, aside from dumping in bacon grease, not much :) Since you're more concerned about cost- you could try running on waste engine oil.
Sorry if this doesn't help so much
