James -

I read with great interest your analysis of wood vs. gas, etc. Being a "newbie" and just started out on this forum (and still in "dream stage" for planning an oven...) I was wondering about air supply to the dome oven/fire.

Have you any experience or thoughts about putting a variable air inlet at the side of the dome - flush to the oven floor, to get air direct to the fire? The reason I ask, is that I think (speculating now) that if you cook not only at the opposite side (of the fire) in the dome, but also in-line with the opening, you would get a cold-air wash over the food.
Also with a side-inlet, you could block the front opening and still have the fire going, possibly maintaining higher heat with less wood consumed (assuming that you choke the air properly so you don't get a blast furnace)???

Any thoughts/comments?

Wow, I feel like i have a masters in wood fired bread making. And "emissivity" my gosh, I haven't heard that word since chem eng heat transfer class, had to go back and look it up.

That's a lot to digest, but I can't wait to experience it for myself, thanks.

I can't think of a better way to blow ash all over your food. It's not generally considered a good idea to have ANY holes inside your dome at all: No ash slots, no air intakes, no vents from auxiliary fireplaces or smokers, no chimneys at the top of the dome. You're trying to build a highly insulated brick chamber to collect, reflect, and concentrate heat. Poking holes in it is counterproductive.
