Ovens, rocket? Mud? ...

Hello. Does anyone have experience using a rocket oven like one of those to bake bread? 

How does it works?

Recently I have the opportunity to bake in a pizza oven, besides it was not very thick (lacked some heat in the end) the results were amazing, so so so much better than my home gas oven. 

I was willing to build a mud oven, than I saw, in the very book I bought, the winiarsky rocket oven that seemed to be more suitable to my kind of use (bake once a week), and I changed my project to a rocket oven.

Now after this experience with the pizza oven I'm again in doubt...

Will the rocket oven give me results as good as a mud oven?

Thanks

Sorry it took me so long to answer your kind post. I've being overwhelmed by others stuff. You know, life is not easy :)

Sorry if I've being rude.

Love to read about your little can oven. Would love to see a picture

The rocket thing seems to involve some technology after all. :)

As I have read the, name came from the sound made by the burner "sucking" in air.

The idea is to have an insulated burning chamber that would perfect the burning, consuming almost al combustible available, resulting in more "heat per log" and almost no smoke (smoke is unburned fuel).

It has being developed in the pursuit of improving health in places where wood burn stoves are the primary cooking arrangement. The goals were to reduce in house smoke and optimize the use of wood.

The key part of the design is the insulated chimney before the stove top (or the oven) that should make a very efficient and hot burning chamber, consuming all available fuel. I've not tried it yet. But If I do I'll post the results here.

There are some insulation in the outside of the oven, but, as I understood, the idea here is a low mass oven.

There are some videos of people using it for bread.

They are usually build with iron drums, not aluminium.

BUT... I still in doubt after trying the power of WFO.

Thanks

Happy baking

I thought my comment perhaps too offensive so I erased it.  You are right.  From what I know, Second burner ovens are more efficient ...and they have to be hot.  Also has to get hot enough first before it can burn twice.  There is a lot on wood burning here in Laos, so much so that the locals firmly object to having a kitchen built inside a house.  (Another topic.).  Charcoal seems to be the fuel of choice for cooking.  I haven't yet seen the compressed coal dust cylinders so common in China but I might have to look more closely.  

Keeping that in mind, would double burning tech be more efficient in the charcoal making process?  Charcoal does have less smoke and more heat, the wood burning phase not.   I plan on using charcoal to heat my WFO for that reason, less smoke, more heat.  

Hi Mini, :)  I can't see how your post could be offensive.

So are you in Laos? I'd love to visit this corner of the world some day.

Didn't know about charcoal being more efficient, or compressed coal dust. Interesting... 

A charcoal WFO (should I say CFO:) is same design but different combustible?

cheers

it works great as  stove.  I also have a design for a masonry or mud / clay oven that is powered by 2 rocket stoves but will probably never get around to building it.  I prefer an oven with mass that can get hot and keep it without tending.  It is hard enough to keep the small sticks fed into the rocket stove as you are trying to cook.  The small sticks burn fast and you really have to keep up with feeding them in leaving little time to actually do the cooking.

These stoves were developed because the large trees and wood were all cut down in much of the developing world but they do have access to small sticks and pieces of wood.  The stove is very efficient for the amount of wood actually consumed.  

Hello Dab. That masonry/rocket project seems very promising, is this your design? Would you mind to share it?

perhaps this is the answer to my doubt...

About the work to keep the sticks burning, I've read that the vertical feeder design (like the second picture) would make the work easier as the gravity would take care of part of the job, never tried though... Winiarski wrote that it's avoided because it is counter intuitive, but it is more efficient.

I'm at Brasil, so in the developing (hope so) :P world, so I can get a lot of sticks. I'm in a city but we do often go to the hills for the weekend, plenty of little wood there...

 

thanks

and 

happy baking

convert it to a rocket oven pretty easily.  That will give me something to do this week:-)  I will shoot before and after photos and mabey bake a loaf if bread in it.  The rocket oven is just to side by side rocket stoves in the back that are 3'-6" off the ground, so they can be fed at the same time by the same person more easily with a  mud oven on top.  The floor is at 4"-6" with the vent at the front.  You don't have to be feeding the fire with a masonry oven while you are cooking and baking.  This design keeps you from having to clean all the ashes off the baking floor before you cook. 

Looking forward to see the photos! 

Are you going to build a mud oven? Or you already have one?

The stoves heats the floor of the oven?

Specially of you are going to make more than one batch, skipping the cleaning of the oven is a great gain.

Very curious with your experiment.

Happy Baking.
