What is the smallest cubic foot workable size for a reduction kiln using p=
=3D
ropane ?. What size are folks using ?
The kiln to be built in question has to have a tall flue 2-3 stories becau=

se of neighboring buildings.
Also is the damper more functional in the flue or at the back of the kiln=
=3D
as the flue exits the kiln?I have seen both but in larger kilns.
this would be a two burner down draft kiln.
what might be better bag walls or recessed flame channel?
Thank you for your thoughts directing me toward answers.=3D2C

Amy,
I have seen an old 7 cu ft electric kiln converted to a downdraft
propane kiln. It has an internal stack which terminates at the lid, so
no external stack whatsoever. Google Simon Leach on Youtube to see his
latest conversion. He used to fire a nice little square kiln that I am
guessing was just a bit more than 7 cu ft as well. Both of these kilns
are fired with propane and weed burners. Mine will use venturi burners
if I can locate another small one soon.

The practicle "Least common denominater" for kilns is usually the size of y=

I have a 2 burner set, Propane 9 cube Fibre Downdraft front loader. I've ha=

The flue effectively ends at the top of the kiln, and that's where the plat=

When I reduce I stick a gas torch into the base of the collector to ignite =

I have fired our roughly 2 or 3 cubic foot raku kiln to cone 10. not
particularly efficient with the gas or anything but it worked. the
smaller you get, the less efficient your kiln will be in terms of BTUs
used to heat a given space. that has a lot to do with simple physics:
given a roughly cube shaped kiln, the larger your kiln, the less
surface area per unit of volume there is, so less surface area per
unit of volume for heat to escape.
