flue liners help

I'm posting this for my teacher, Mary Law, who is not on clayart and a bit of
a Luddite about computers.

Does anyone know anything about flue liners? She has a 12 year old gas
reduction kiln, fires cone 10, and the metal stack is deteriorating (flaking)
to the point of glowing red last firing. The chimney is brick on the bottom
3-4 feet and then the metal stack up through the roof of her studio. The
chimney has to be replaced but she doesn't want to use brick if she doesn't
have to because the diameter of the stack would be smaller, etc.
She was thinking about replacing the metal chimney with another one with a
flue liner, if they are available. Let me know if this is enough information.
Thanks for any information.

Check ouit the chimney info in Nils Lou's book, The Art of Firing. He
gives a source for ceramic fiber flue liners. I use them and they are
quite effective inside a metal chimney.

Flue-liners (sleeve risers) are available from Fire Brick
Supply in Minneapolis (only place I've found them ready-made and
available and reasonable). They come in one-foot lengths. She
should call first, to see what is available in terms of outside
diameter and inside diameter, before she plans her new metal
stack. They work very well. Shipped UPS.

When my old fiber kiln with a metal stack needed to be refurbished, I used
a double wall sheet metal tube and lined it with commercial fiber tubes.
The outer wall was 12" diameter, the inner metal wall 9" and the fiber
liner inside diameter was 8". The outer wall did not get too hot and I had
no trouble wit it for years

is tempted toward 70 deg.

There is a rule of thumb to use brick to the height of your kiln and then
switch over to and non combustible channel directing the stack air such as
metal or flue liners. She will still need fire wall grade protection through
the wooden roof <- usually triple wall stove pipe.
I had a red chimney the first time I fired my new fuel oil kiln (1980) and had
gone too soon to metal pipe. It got corrected before the next firing.

Flue liners should be available locally at any brick yard that sells bricks,
quarry tile, and flue liners. They come in various sizes and are fairly
inexpensive.

Francine:

I have used a metal well casing, 10" diameter, for the top of my kiln's
chimney for about 20 years, all of it exposed to weather and it only needed to
be replaced last fall with another piece of well casing when I was rebuilding
the chimney anyway. You can tell Mary Law to look at a local junk yard which
salvages metal. They come in different thicknesses, up to 1/4 " thick, which
is fairly expensive. Also tell her hello from Jane in Aromas. I had supposed
her new sodium kiln was so fabulous that she wouldn't want anything to do with
the old one... :)
