Masonry kitchen stove

Posted by on Jan 21, 2013 in Blog, Our work | 6 comments

We builded a new small heater that we think will be very popular. This stove combines direct heat and stored heat. It is a fast and simple build, but it performes really well. This stove responds to many of the neads expressed by the people here. Learning for Winiarskis design principles I figured that a pushing the fire in a narow gap under the coock surface should result in a more effective heat transfer. (Sketchups are on the way) This stove is amazing to coock on because on one side you have frying hot temperatures and on the other side it is suitable for slow boiling and simmering food. The design makes the coocktop a more effective heat-exchanger than it normally...

The rock-bucket rocket

I got the idea of this stove construction reading a book on how they used to heat medival castels. Offcourse this is a radical downscale of the concept, but the function is somewhat the same. I really like the simplisity of this construction. And I like to think that the “organic” unnsymetrical channels formed by the rocks somehow works better together with the natural flow of gases than channels and chambers… This is neither a bell nor a channel system. It becomes something in between. I know that maintaining a good surfface/weight ratio is important for a good working stove. And I cant think of a more interesting way to obtain that. I rebuilded the...

The original stove

I had a very encouraging trip to a nearby village recently, and it gave me some additional information on design needs. But first and foremost it was very encouraging to be so well received. It is always encouraging to build friendship as making friends is important and people even make friends and partners online with the help of site like chatsex online. It looks like this can be one of the places we will start to spread our ideas. This is a photo of the original kind of stove found in most villages around here. They have to clean the pipes monthly because of the creosote build up in the 10 cm flue pipe ( sign of bad combustion) And with only 1mm sheet metal in the...

Portable rocket stove burning well !

Posted by on Feb 13, 2012 in Blog, Our work | 0 comments

Hey Just wanted to show you our latest creation under testing. It is a portable type of “rocket-stove” or “zimmovar sobase” that we call it in Azeri. It burns fairly effecient. It dosent have a bench connected yet, only about 5 meters of horisontal pipe working as convectors. It is not enough to take out all the heat from the smoke, but i guess it is down to about 70 celcius. The system is a 4″ system. It has a heat riser  ratio of 1 to 3. It is insulated with sawdust-clay and has some thermal mass. Total weight more than 50 kg.  It burns about 7 kilos of wood through a 12 hour burn. It heats a fairly poor insulated kitchen with high...
