The Rocket heating part is experimental. It is not new. So we are playing with the addition of a seperate heating mechanism. This could (? lol) be a way to boost the oven temperature up if you wish to. Cleaner and quicker than putting a fire in the burn chamber again.
It seems to fire well at an angle. The thin metal tube is covered with ceramic fiber blanket and can also be dismantled for refitting without taking the whole contraption apart. The fire chamber has a layer of blanket under the top bricks too. The FB Should hold better.
I stuck a seperate air intake with a damper in it. Why? You might ask.. lol.
There’s a few more pipes in the the pipeline (like that?) and plenty of variables to play with.
At best – we can learn something. If need be we will fire as a two chamber oven anyway.
Nothing ventured, nothing gained.
Busy drying the oven out:
Starting with a small fire in the oven. Using some Live Oak. Hard and burns great if it’s dry.
The Rocket draws very well. Ceramic fiber blanket insulates from the heat – but even so it gets pretty warm!
