There have been threads on this type of burner for the last couple of years, maybe three. I'd like one just because its a new idea, but I'll need to wait until the price comes way down
jet fuel, I think. loto stoves been coming out including the 111C advertised as able to use jet fuel (high filtered Kero) kinda spendy, but, if you work at a base?...
JP-8 is a grade of kerosene. the US military uses it and one other almost exclusively. rik-uk3, do you know if they're on the market yet? it would be great to have something more to read on the design.
It appears that MSR has been concentrating its efforts on its Reactor Stove project instead. I'm beginning to think this stove is just Vaporware? Manny
That page has been there for quite a while... There was another one recently that claimed The 10th Mt division at Ft Drum was testing these... There was an updated photo...Which I saved of course...
JP-8 is the US name for NATO F-34, and contains all the same crap - i.e. Fuel System Icing Inhibitor (DIEGME), not to mention other stuff that *may* be added to it including anti-oxidants, metal de-activator additives and anti-static additives (none of which are particularly nice) Would I want to be downwind of it when its burnt? Nope.
thanks.. I thick Iv'e been looking for them to come out for at least 5 yrs maybe 8. Always next year. the ceramic wick thing ain't changed as well as the buff plate. O.k. who's made one at home ..own up... Think I will probably have to try one day.. Jet fuel hobbo I believe its a high octane petrol with lots more nasties than regular petrol Jet A = kero which may contain some stuff but not supposed to.Seems slightly heavier and not as clean burning than good grade kero Jet A1 = kero with anti icing and all sorts of crap for winter in it. Think jp4 is petrol type with more nasties in it also.
I could be wrong, usually am, but I think the only people making an anyway silent, liquid fuelled stove these days are Coleman. Once Optimus scrapped the Cobra burner and used the Nova burner for the 111X then a piece of stove history ended!
barrabruce, just an idea,......but I was thinking a person could use clay(or similar) to mold the 'ceramic' wick. by placing extremely small diameter threads into the clay while it's still moldable then baking,...you would burn off the threads, harden the clay(wick) and create the capillary feeds. Seal the outside and you're rolling. From the one article, they have progressively smaller feeds/capillary lines in three phases, ultimately resulting in a barely porous wick on top. It seems to me you would need only two phases for the wick. One to feed from the tank, and the gas burner. Clay itself could be a problem because as it would deteriorate it could clog. Extremely crude, but that's my thought.
I also had some thought on this a while back. From what I understood, the "puck" is made of three ceramic layers: Top layer: Basically a nipple or jet, only it's ceramic and bonded together with the next layer. Functions by collecting the fumes from below into a jet, and slos directing heat downwards. Middle layer: Porous but very dense ceramic layer, where the fuel is turned into gas, by the heat from above. Bottom layer: Very porous material, basically just a "ceramic wick" I went out and bought some brass water pipe fittings (female and male endcaps) with an inner diameter suitable for slotting in a "ceramic aquarium bubbly thingy" My plan was to drill and tap a hole in one of the end caps, fit a jet from a stove in it, and let this substitute the Top layer, then put in a middle layer and then the aquarium thingy at the bottom. Since the middle layer is where the magic happens, it would need to be a trial and error testing of different materials. Since it' supposed to be pretty dense, but still have some capillary properties, your idea could work very well. I hade some thoughts on asbestos like packing material, fireproof mortar, or other similar pastes. Basically I aborted the whole thing, since I realized I don't have facilities for that level of tinkering at the moment, and also should bloody well write my final thesis already, instead of letting myself slide into stove-o-mania...
Wouldn't the ceramic wick conduct the heat into the tank?? Tried an aquarium stone once too. Soaked in metho. The one I tried decinergrated into corse sand. Must have been glued together. Pumice stone or sharpeing stones may be a sustitute for ceramics. the sealing the outside be the hard bit.And getting the porosity right. Doubt if they will ever get it to work for long. I mean crap kero in a wick heater clogs up apparently so finer ceramic stuff somehow performs miricles with real crappy stuff?? Bruce
Good to know about the aquarium stone.. I'm guessing anything we could make will be not as good, and a lot more expensive than the real thing. I'm thinking they'll combat the clogging problem buy handing out spare tablets by the dozen. They should be very cheap to produce when you're doing it at that scale. The interesting thing would be to build a new design, utilizing the real tablets if and when they're available in stores as spares.
