14.2g Canister stove

Postby Tony » Thu Jan 10, 2008 11:38 pm

This little canister stove I made last year it weighs 14.2 grams (0.5 oz).

The stove is made from aluminium (burner cup and valve body) and Titanium (mixing tube, needle valve, burner plate and pot support legs) the only part that I did not make is the brass jet which I have modified to suit, the needle valve handle is made from Beryllium copper wire. I have also put a flow restrictor in it to slow the gas flow down to suit the small burner.

This stove is one of my favorites.

Dude!

Now that's impressive! What's your effeciency? That's got to be hard to beat weightwise with an alcohol stove.

Hi Skids,

I have not done seroius efficiency testing on this stove but it uses about 6g of canister fuel to boil 0.5l of water which is comparable to most good comercial canister stoves.

I have played around with some lighweight canisters for this stove (picture below).

Please excuse some of these pictures are from a slightly heavier version

nice!
oh to have a machine shop at my disposal... (bmike sighs...!)

well done. i'd be curious about eff. of the stove.

i have a tiny butane mini torch that i eye for turning into a stove. i'm a bit scared of blowing the garage up - so i keep my eyes posted for the proper tip that would spread the flame out...

Hi bmike,

I have nearly burnt down my garage several times and I have many times when I have burnt the hairs off my hands with both canister stoves and alcohol stoves.

One problem that I have is that as I have been playing around with stoves for several years now I have become too complacent, the other day I knocked over a burning alcohol stove right on top of three plastic containers of alcohol about 5 litres, I now store the alcohol in another part of my garage.

With canister stoves I have had leaks that have caught alight near the canister it is a bit frightening.

Nice thing about stoves that are filled with wicking is they absorb and hold the fuel in a safe fashon. Knock it over and the fuel remains intack. The "Starlyte" is one of the best safe stoves. ;)

Tony, what's the function of the large holes in the vertical black tube?

Hi Zelph,

Tony, what's the function of the large holes in the vertical black tube?


The holes are to suck air in to mix with the fuel, it is then entrained in the turbulent gaseous jet. Most of the air required for combustion is sucked in through these holes. I put a lot of time getting the jet size and mixing tube right to suit the small burner and , it is not easy to get right.
