Re: 81 Inch First Build (and first post)
Yeah, I was wondering which way the heat would go, from dome to flue or the other way around....
The swirling concept might be accomplished by angling the incoming air slightly so that is favors the right side wall, the fire side. The roof bricks just above the arch would have a path formed from the top of the arch towards the left and the flue would lean upward, towards the right...so...the air would form a slow rotation counter clockwise inside the oven. Works on engine intake manifolds...after all, every bit of hot air expelled from the chimney top is sucked into the front of the oven, right? Might as well get every bit of efficiency out of it.
I have thought about wrapping a few turns of 3/4 inch copper tubing around the outside of the dome, under the perlite and hooking it up to my hydronic floor heat system...pump, valves, resevoir, load....sounds simple. One could also use it to take down the oven temp if needed too.
Great discussions.
