Our large ar kiln is inside and approximately 15 feet or so to the ceiling
and then another 24" of roof truss to the exterior.
We used stainless steel custom made flanged 10" dia pipe to about 4 feet
below the ceiling. There are special locking bands that go over the flanges
on the ends and lock them together into a very monolithic unit. Then triple
wall Metalbestos through the ceiling to the outside, and the usual
stainless flashing system and roof caps. There are a number of grades of
Metalbestos, and our system has functioned perfectly for many years. We use
the highest temperature rated Meltabestos. We also removed a 36" x 36"
section of ceiling to create a box through which the pipe passes. It is
lined with fire resistant drywall. The pipe runs through the center so that
there is adequate clearance between it and any possible combustables.
I have also used at times riser sleeves inside of galvanized
conduit/corrugated tubers from the builders supply. We coat these sleeves
with a very thin mixture of castable refractory coating and let lower them
into the tube and let them set up and bond to each other. No problems on
the last kilns designed and built for Castle Clay Artists in Denver and
Potter's Wheel here in Steamboat Springs.
