Can't seem to find much information in english language about these. Concept seems simple enough, but I wouldn't think the metal at the inlet interface would last very long. Do we have another name for this design, or anyone know about its efficiency? DesignYoutube video loading/lighting |

I would question the efficiency since the gases aren't being pulled downward. In addition, there is very little mixing in the above chamber.
I have seen similar metal setups but they usually have the fire on the bottom of the barrel along with an exit flue/venturi.
Glad you shared this.

Darn it. My power went out. (Storm)
The stove looks like a standard gasifier but not a downdraft.

Dkeav, Last year there was a rocket stove/gasifier combo that used sawdust or woodchips and burned in a barrel drum. I am unable to find that specific video but here is a similar stove. There are many more like this on youtube.

So far, the gasifier/rocket combo stoves that I've seen looked like nightmares..
I'm sure it can be done well, just haven't seen it yet.
That sawdust stove is pretty cool though.

There can be an argument made that a gasifier/rocket has already been done before with the old Jetstream furnaces. I don't know. I go back and forth on the topic.
Sometimes it might be better to pick a style:
The inventor could easily go with either a plain rocket or seal up the port and create a gasifier with a rocket core.

Thanks for being so cool about stoves, Donkey. I mean that.

The big mistake that I keep seeing with the rocket/gasifier combos is that heat is taken from the burn chamber and heat riser to run the gasifier portion. The most common configuration is an uninsulated chamber surrounding the heat riser, full of wood chunks with an opening from that chamber down into the burn tunnel for wood-gas to feed the flame below.
Seems to me that the same thing can be accomplished by making the heat riser about 1/3 taller with the bottom half insulated and the top half arranged more or less as above.

hello, have n t been back on forum for awhile, (but have been browsing it now and again ), has anyone tried out these bubafonya stove ideas , i am thinking of building something as a long burning heat source to an insulated boiler tank for pumped hot water supply , theres a fair bit of info on them ,mostly on homemade heating type forums in russian .Goggle translate is brutal into english ,but its good enough. Seems a rugged system and perfectly do able with limited equipment and scrounged bits and pieces---i would nt say fool proof ---as a caveat in case you dont here from me for awhile -and presume the worst--

Just saw something about these stoves over at Permies, and found this thread via goggle.
The stoves are interesting but I can't imagine they are very clean burning.

so no ones built one yet , but it looks useless ,suppose thats it then , not much point in going further with it, i will have to read up more on the vortex stoves and start purchasing firebricks or learn how to mine magnetite , if i can find a seam of it, my budget is not eco fiendly at the moment
