Yes satamax acacia = Black locust . In my area it is everywhere, along with oak, maple , wild cherry , beech is forbidden to cut

I do not exactly get the idea why you want to seperate the bels and not make it a one bell kitchen. Ps. its nice to see you used some of my design of the core with tripwire and p-channel:)

Hi Robert In theory they are two bells, I hope you do not mind if I use your design :-). Actually the project that I use is different but I used your project as a graphical representation. What do you think of the kitchen?

No i do not mind at all... I am very happy that it can be used by the others, thats why i tried to do it and get the explanation about the modification on the J-Tube that was made by Peter.
Regarding your design. Take a note that i am not an expert and i am learning as well, so all of i can say is just an assumption. I kindo of like your design but i do not understand why you want to devide it into two bells... I been building one kitchen range recently and it was one bell...
the heat will evenly be distributed and the highest temps will be just under the cooking plate... that willbe good of course for cooking...
than what i think regarding the oven... you will have the main heat above and around the oven... and little lower temps at the bottom... in this way you will not burn the bottom of your bread or any dish...
than about the heat exchanger... if you place it horizontally you will also collect more heat than if you place it verticaly.
these are mu thought and woul dbe nice if anyone more knowledgeable comment on this as well.

Can someone give a link to what a broken riser is. I've not heard of this before. Cheers, Martin.

Hi Robert. thanks for reply. I'm no expert. I saw that build stoves regularly, you're lucky :-) My intention to divide the bell is dictated by the belief of getting better so to warm the oven, in a single bell the distribution of heat is hotter at the top and then the bottom of the oven will be significantly colder, it does not happen (maybe) if the gases pass around the oven. I have a question for the heat exchanger, this location was chosen because I intend to use a natural circulation of hot water, heating the upper part of the heat exchanger (hotter at the top) will lead to a better circulation ... this also happens with a horizontal heat exchanger ?

Matt, acacia = black locust. Peter, i've had a thing rumaging through my head lately. In cases like this, i think we could do an "horizontal riser" I know it's impossible with a cob bench. But with a bell, we could keep a feed tube or batch box, along burn tunel, where the gases would all be burned. Then that would spread into the bell, cooling somewhat. Then go up an insulated chimney with the mouth at about the same level as the burn tunel. Like separating the elements forming a rocket stove. We would have to keep more heat to power the chimney. But who knows where that might lead. Interesting thought Max. I do see where you are coming from on this. As long as the draft up the vertical chimney is strong enough the burn might be pretty complete by the time it exits the long burn tunnel. Laminar flow might be a problem as there is no disruption with an angle going to the riser section but maybe multiple trip wires or something of the sort could overcome that problem... that is thinking outside of the box for certain Max.

Cramer, just a batch box, with a port, and a long burn tunel behind.

Hi Robert. I believe that in a system with a single bell rather high the sensible choice is to put the oven on the top. But this is a kitchen I have to have the heat for cooking and the position of the oven I think is the most sensible in this case, using a single bell fear that the oven does not heat up enough. The refractory material of the oven will be from 3 cm. The heat exchanger inside the bell of material that should be? I thought the copper ...

Cramer, just a batch box, with a port, and a long burn tunel behind. I have been thinking about this too - to the sides or bottom. There are downdraft furnaces with chambers for the feed and combustion side by side. I wonder if the same could be done with a rocket stove? Feed the heat to a third chamber doubling as an oven. All side by side.
