Hello,

I have an idea but i don't know if it works.
I have build a lot of wood gasifier stoves for bushcrafting as you don't need much wood as fuel, it gives just little smoke at the ignition and once it burns almost no smoke.
I also have a small rocket stove and it also burns perfect.
I was thinking about making a wood gasifier that has insulation so it burns hotter and cleaner (like a wood gasifier in a rocket stove)
Will this work?

Gr. Matis

Hi Matis,
Sorry no help from me, but here is a link to a site dedicated to rocket stoves; maybe you can get some traction over there:

good luck!

Sounds like a great idea! If this hybrid process can increase riser temps, it should increase the draft though the stove. Can you post some pictures?

Actually i haven't made it yet, but i'm going to build it.

I don't know if it would be possible to put a barrel on the wood gasifier so it is like a rocket mass heater. Will this work?

Don't why not. Maybe a double wall riser to bring the wood gas from the combustion chamber to either higher up in the riser or to the top of the riser. Tinyhouseblog.com just had blog post on a rocket stove boat heater. http://tinyhouseblog.com/heaters/roger-lehets-kimberly-stove/ Check it out!

I've been tinkering with a rig to get a hotter flame for boiling maple sap.. This is my first attempt-- Rocket Stove (5 gallon bucket with ash insulator, 6" stove pipe burn tube, tin can feed with tin can feed plate. Gasifer sitting on top, a piece of double-walled stainless pipe I had laying around. Some metal mesh is crammed in the bottom for fuel to rest on and holes are drilled around the top (gasifier jets). I put the gasifier on top of the hot Rocket and the thing really took off.. just few handfulls of grass pellets gave me 4 foot flames. Will try to figure out how to attach a video... (doesn't want .mov or .m4v extensions?? Will explore further. Here's screenshot...)

Not good. CO output from solid fuel cook stoves is higher than other fuels. Using them indoors without an integral flue to the outside poisons people.

The glowing metal is good, that means you may be reaching the needed temps. The Orange flames are bad, that indicates unclean burn. I don't thing a clean burn can be achieved by a 5 gallon bucket based system as it's just too small. I haven't seen one that doesn't have evidence of unclean burn written all over it. Keep up the experiments though.
