Hi folks,

I am ready to begin assembling materials for a kiln, having just gotten the
funds to build.
I am planning on a 24-30 cu. foot (usable space)downdraft, propane fired
car kiln. I have seen two designs locally that seem fine with just one
major difference. One design has four big burners facing sideways into the
kiln and the other has eight small (Venturi) burners facing upwards into
the kiln. Would anyone be so kind as to go into the pros and cons of these
two possibilities?

Thank you muchly,
Michelle, who will have more cone 7 glaze results to post soon.

The side mounted burners require a bag wall and because the flame loses some
velocity, I imagine the stack would have to be much higher than the bottom
mounted burners. I have a Berman downdraft that is fired with six small
burners positioned beneath the kiln. It has a stack only as high as the body
of the kiln measuring up from the firebox\flue exit and draws remarkably well.


Good luck!!

Michelle- Why don't you consider 2 burners firing forward on either side of your
exit flue? With the proper btu rating (orifice size)- 2 burners are much simpler
& with my experience more controllable. Read Nils Lou's book- The Art of Kiln
Firing- & modify for your own needs. If you are interested in an inexpensive
burner system- Big Berthas are hard to beat. 2 of my favorite potters use these
burners(Tom Turner & Ellen Shankin) & they get good consistent results- as we do
here.
Good Luck w/ your kiln building-
