Building a gas fired convection oven for
powdercoating
+++
I was using a brick oven to cure my powder coating which were
small items. Now the project is expanding and I need to build a new
oven. I cannot use electricity, as that commodity is very expensive
it was suggested that I use lpg (liquid petroleum gas) so I need to
build a gas fired convection oven. I have worked the size as being
8'H*6'W*8'D or 384 cubic feet. Mow my dilemma is this where do I put
the fire box(area with the burners) at the bottom of the oven area or
to the back and where do I put the ducting for the fan, top of the
oven to the front/top of the oven to the back, and how wide do I make
the ducting. Looks like I need more than 1 fan. Lastly what would you
recommend to line the interior of the oven area, high temp paint
or....,I have used 1/8" thick mild steel to make the oven area
already cannot afford stainless steel please help in the poorman's
way as possible. I've just really started.

Hi, gentlemen. I strongly recommend "Powder
Coating" by Roger Talbert -- a 141-page softcover
published by Chemical Coaters Association International,
Cincinnati (ccaiweb.com). It has a 10-page chapter about
curing ovens, with sketches, as well as info about dry-off
ovens. It is not a set of plans, but it is invaluable and it
clearly explains the features that should be included in
each type of oven and why.
You will probably also find
letter 33629 informative.
Good luck.
Regards,
