Could something like this work? the oven would be heated from above unless the direct to chimney opening is closed then the gases would pass through the oven (effectively a bell). oven would be a sheet metal box with some sort of insulating board around the back, bottom and one side. I apologize for the crudeness of my sketchup.

Can't see the picture, sorry.

I see nothing wrong with the design.

Is there an opinion on usability of the black oven? I have used cob ovens for bread but that is my only experience. How does a casirole or a quick bread do in such a drying environment? Also opening the oven door will probably cause smoke back? I had also though to circle the heat on the extrior of the oven chamber but from Cook stove experience this is a pretty slow route to a baking temperature.

I can't picture where the oven is in your proposal. Is it beside the firebox and the exhaust gases come down through that square box like thing at the back right?

The oven is the blank space to the right of the firebox. The entry is in the rear corner next to the expansion chamber. The square in the opposite corner would be the entrance to the chimney and would have a bypass.

I had also though to circle the heat on the extrior of the oven chamber but from Cook stove experience this is a pretty slow route to a baking temperature. I think I would make the entire top a cook surface with a bypass at the right rear of the top. When the bypass is closed it would force the exhaust down into the bottom right which would serve as the black oven and have an exhaust at floor level. Open the bypass before opening the black oven door to prevent smoke back and allow exhaust to escape the black oven. .

and a gamble to say this because it depends on the type of construction of the stove and the oven, but in my experience I tried to open a cleaning door during the operation of the stove and the smoke did not come out. maybe someone more experienced than me will know why. an idea but I made it, I do not know if it is correct. I think that the environmental pressure is higher than that found inside the stove, the chimney creates depression and if the chimney is long and isolated the depression is high, this could prevent the escape of fumes when you open the door of the oven. my doubt is that if this thing happens even if the oven is positioned in a part of the stove with relative calm it could be the top of a bell, where the hot fumes are stationary, and there are no small steps that increase the speed of the gas and help to direct the smoke along the channels. Peter, given his great experience, could perhaps evaluate my reasoning and express an opinion. regards

You beat me to a new thread Joseph I have a different solution that I will post in a few days when I have completed the drawings... still learning SketchUp so it is taking its time. It is good to see how you think. Esbjorn
