    It's a good system for occasional use, Kevin, but I think it would be too expensive for a liveaboard or even someone who enjoys cooking at anchor.  Here in NZ, these containers are difficult to recycle - I suspect you have better facilities in Europe.

    I also did not like to have gas piping and gas canisters on my boat. Especially since there was no proper space for the canister to be stored, so a leak could lead to an accumulation of gas in the stowage areas or bilges

    But my solution was to put a new single burner cooker in the gimbal space where the old cooker would sit.  I chose a cooker that would run on butane and added a connection for those small aerosol sized butane cans for camping and gardening uses.  But unlike the cheap butane camping stoves, my burner is explicitly rated for indoor use.  So now I can boil a kettle in under five minutes (that’s 90% of what I need a cooker for) and when I am finished I just take off the aerosol sized canister and leave it outside in an open area.

    A few bolts through non functioning bits of the stainless steel cooker top provide added insurance that the kettle/pot will not move about.

    Am I missing something about butane or is this not as easy and safe a solution as all the alcohol burner stoves?

    Hi Mark,

    I just realized that there is already an existing thread with relation to the rocket stove concept. I'm going to post it there.

    Cheers,

    Paul

    It is only loosely related to this thread, but some years ago I built a rocket stove oven for my former Scarlett. The top plate of this wood stove got 250 - 300 °C hot, depending on the wood used, and we used it oftenly to boil water, cook noodles, etc...

    I wrote this article on my blog, have a look:

    Great work, good to see a proper Rocket stove that has the insulated chamber and downdraught. 
    i see you also use pellets, a good option.  Can you show a photo of how the feeder works. 
    ps.  I have a small camping wood stove, basically a fire box with quite a tall chimney.  It definitely is a lot less efficient than your Rocket stove.

    Not wishing to hijack this thread, but as it's about stoves and cookers, I wonder if anyone could suggest a readily available material to use in a trangia to soak up the alcohol, in a similar manner to the Origo does.

    Maybe it wouldn't work in the Trangia, but it would help prevent spills if it did.

    I would imagine ceramic fibre would be better and I will test this, I have ceramic fibre and some trangia burners. I reckon it won't work though as the Trangia keeps burning until the last drop of ethanol, by which stage the flame would be below the top of the fibre which would then blacken and clog up. The Origo uses ceramic fibre, the Compass version uses cheaper rock wool with a thin layer of ceramic fibre on top. I can post a sample of ceramic fibre to you David D if it looks useful. I think a wider, larger volume, Trangia type burner would be great, can anyone here weld one up from Stainless Steel or brazed brass?

    I've find this video about modifying a Trangia burner.

    The video focus about efficiency but any boiling test has been done.

    Despite that, the modification presented could be a good idea for soaking up alcohol and avoid spilling....

    If I remember correctly, that stove transports the fuel to the burner via a wick.

    That would be quite interesting, indeed, Toni! It would explain a bit, why slightly pressurising the tank didn't show a significant effect. However, it would not explain that when the valve is opened in cold state to fill the preheating dish, there is some fluid flowing out rather fast. Too fast for a wick, I would guess. Did you open it up once?


    No, I haven't taken one apart, but the stove manual says;

    'Nach dem Füllen 2-3 Minuten warten, damit sich der im Vergaserrohr befindliche Docht mit Spiritus vollsaugen kann.'

    Which translates as 'Wait 2-3 minutes after filling so the wick in the fuel transportation tube can become saturated'

    I made some good experience with fire-resistant carbonfibre mats, using it as an eternal wick for candles. You can get it from bbq or welding supply. It might also do the trick for your needs.

    Some fotos of the Salsa/Mamba burner:

    foto 1 & 2:

    the fuel runs through the lower, long pipe, which goes through the actual burner. Then into the thin, vertical pipe, which includes a nozzle in the top region. This nozzles faces into the open, upper, vertical tube. Which then leads into the upper burner part and distributes into the burner nozzle ring.

    foto 3:

    filling the preheat dish with cold, liquid ethanol from the nozzle. You csn see the stream of liquid flowing out.

    foto 4: 

    preheating

    foto 5:

    steady burning after preheating, ready for cooking. The valve is fully opened. Note: there is no liquid flowing out of the nozzle anymore, only gasified ethanol. I guess the aim of that nozzle-into-open-tube-design is to generate a burnable mix of gasified ethanol and oxygen.
