Hello.
Next time at my house on the Philippines I want to create some stoves build from clay.
To play with designs I've got some parts for air ducts.

I have already a fire place in a classic German design.
Two fires for cooking and one for burning waste.
The doors are still missing in the picture.
In tests with provisional doors it worked very well.
I had to leave before it was finished.
My mother in law has problems using it as it is to far away
from the vernacular fire places.
The the mostly used small ceramic improves little over a three stone fire.
Stinking and unhealthy.
As I was young I've worked as a model maker for foundries.
Building the stove will be no problem.
What do you think about the designs for the rocket?
Makes a venturi any sense at all?

Does nobody have to say something ?
Theoretically a combination of the first and the third with some second air in the smallest profile would give th best results.
So far I have been quite successful in translating my knowledge of physics into something working.
However there are often side effects not taken easily into account.
Thus I was hoping someone else may already have tried something in in this direction and could share some insights.

I think "conventional wisdom" (if something as new as rocket stoves are allowed conventional wisdom!) says there shouldn't be changes in cross sectional area. Perhaps you should explain your thoughts about what the venturi would do. Since there's supposed to be flames / flame temperature gases in there, they should be moving pretty fast already.

Among other things Venturis can be used to add something to a system and mix it with what is already inside.
( can be used for separation and removal too )
I want to benefit on the effects used by airbrushes and Bunsen burners to add some second air to establish
an afterburner for faster, cleaner and healthier cooking and saving some fuel.

I would certainly run this set up outside first to see if there is really much point. If I was in the Phillipines, I would be looking at these. |

Building one self is more fun.
And for the people there:
The cheapest is 1500 PHP, which is a whole monthly salary for lower work in many parts of the Philippines.

Building one self is more fun. This is true. I was not necessarily suggesting you buy one, for the reason you stated, but they are the sort of stove which can use waste from production to keep the running cost low. You could download this which is a complete book including build information. There is a continuous burn model in existence, but there are no drawings around. This is a simpler stove. |
