We have a kiln(s) at my College that use this. They are small "coffin" kiln=
s
(4 bricks wide 15 bricks long, 5 bricks tall I believe). They share a
chimney, we use kiln shelves to damper off the one not being used. Fire
pretty good. One we only fire to ^06 the other we've had up to ^6.
I believe my professor got the design from a kiln at a University in
Australia, he took a sabatical there 2 years ago.
I, however, don't know what school it was off the top of my head.
Do you have any specific questions?

Jonathan -
You can do that. The only downside is that you cannot fire both kilns
simultaneously. When firing one kiln, you would need to block off the flue
in the other kiln - just put a kiln shelf over it with a few bricks holding
it in place. Or, if the damper is between the kiln and the chimney, just do
the same on the second kiln, and close the damper completely on whichever
kiln you are not using. If you want to be able to load and fire one kiln
while the other is still cooling, then you would have to use the latter
system - with each damper located in horizontal flue between the kiln and
the chimney - that's the only way it would work.
Good luck -

hello, i am new to the clayart list, so hopefully i have posted this
correctly (and if not i am sure that i will hear the wrath).
my question is if anyone on the list has experience with sharing one
chimney with two kilns. i have seen a few pictures of this , but do
not have any practical experience with doing this. it was a
consideration i am having to build another kiln behind one that i
currently use, and tie into the chimney to save bricks.
any thoughts?

We're not big on wrath here, but there might be a considerable
amount of eye-rolling and moaning. (But not from Gayle, she's
just crabby, LOL owww! quit pinching me woman!)
If both kilns require the same amount of draft opening
so that your one chimney can work for either kiln, you should be all
set in your plan. That said however...
=20
* Be sure that when chunking out the opening into the base of
the stack for the new kiln you don't weaken the support for the
chimney too much, or the whole thing will come down.
=20
* You will need to find a way to close one kiln off from the
stack while firing the other, or suffer draft problems on each.
=20
* Last, (obviously), you won't be firing them both at once.
(That wasn't a question)
=20
You might want to look at putting in a damper for each kiln, so that
one can be shut off tightly while the other fires. That's one way.
Or a damper in the stack itself for both kilns, used for whichever
you're firing. Then you still have to block the other kiln off when
firing.
=20
This has been discussed before on the list. You will want to check
the archives here: http://www.ceramics.org/clayart/

Good Luck!

hello, i am new to the clayart list, so hopefully i have posted this
correctly (and if not i am sure that i will hear the wrath).
my question is if anyone on the list has experience with sharing one
chimney with two kilns. i have seen a few pictures of this , but
do
not have any practical experience with doing this. it was a
consideration i am having to build another kiln behind one that i
currently use, and tie into the chimney to save bricks.
any thoughts?

i don't see why this wouldn't work. and i suspect firing of only one kiln at a time would happen.
see ya

Thanks for the prompt replies. i wasnt planning on firing both kilns
at once. thanks for all the input, sounds like it should work,
depending on the draft requirements.

Don't waste kiln space! By building two kilns together, back to back, the
spent fuel from the first, a downdraft, can be used to bisque fire
in the other, an updraft! I build and operated this baby at Haystack summer
session yrs ago. Go for it, you won't regret it!
