Rocket Stove with baking oven and mass heater

[ragulka]

Hi, i am new to these forums but have read and gathered info about rocket stoves for about a yera now. I've read the Rocket Mass Heaters book all the way through

Anyway, I am trying to see if there's a way to build a more conventional-looking stove/mass heater using the rocket as it's core.

In Estonia, where I live, we have a lot of stoves that look like this: www.kuldsedkaed.ee/wp-content/uploads/2011/04/Pliit-ja-soem%C3%BC%C3%BCr-1.jpg

The good thing about it is that it has both normal stove and the baking oven. And I'm trying to replace the normal cor with rocket.

Here's a quick and dirty sketch I did tonight based on my readings about rocket stoves and rocket baking ovens. It's top is supposed to be the stove and the baking oven is in the centre. I am also toying with the idea of having a glass door with air intake from outside, or somewhere else (not on the sketch).

Any comments and feedback is really really welcome.

In your drawing a heat diffusor is missing.
A diffusor is needed to prevent the flame hitting the bottom of the baking chamber directly.
If the flame would touch the bottom directly it would create an extremely hot spot, burning the baking goods.

There is a rocket baking oven manual, which you could downsize for your needs.

Sorry, you will have to copy the whole address.
It's not working as a link in my post because of the spaces in it.

Hey karl, yes, that is certainly missing from the drawing. In the book I see there is a thin line just where the flames would hit the bottom of the oven, this is it, right? And i also see clay tiles for heat retention.

Yes, it is the thin line.
Additional mass by clay tiles is not only for heat retention, but also provides a more evenly heat distribution.

Do you know what the thin line should be - metal?

Usually some kind of ceramics is used as few (expensive) metals can resist such conditions for any longer time.
Metal diffusers ( even enameled ) as used in lower temperature and low corrosion conditions will fail.
A disc made of fire clay should do the job.
