Out-D alcohol stove -how do I get blue flames?

I purchased this small alcohol stove, a Chinese knock off I believe from some older American made stove.
I have used denatured alcohol (ethanol) but for the life of me I cannot get the solid blue flames I see in some videos. I have only fired it up outdoors at temperatures near freezing. The main flame is quite large but the flames from the jets at the circumference are quite solid yellow. Is there a solution to this?







I inverted the cap and put some water in it and placed it over the complete stove opening so as to get only the jets operating but no change.





It should burn as in this video.

 

it isn't you fault, most probably it's the meth you are using, containing some sodium, the flames you shoe (please correct if I am wrong) doesn't blacken the pot bottom, so the problem of flame color is not incomplete combustion.
Try "bio ethanol" fuel for decorative fire pits and let us know.,

 

I am using this.

 

I’ve had similar results to @Blueflame ; I wonder if having a pot on the stand makes a difference.

 

An interesting post. I have one but have yet to try bio in it, the standard meths produced the pure blue as I expected.

It may be a little while before I get an opportunity to do a test. The bio I have works OK in the Turm, so I would anticipate the same burn result in the Out D (Simon) stove.

 

I also used Isopropanol (99%)...same results.

 

I've used my Simon stove with pure methanol and also with methylated spirits, both giving blue flames. Maybe the Chinese copy is not truly identical? One would need to compare them side-by-side I guess.

I think you may have the answer. Do you have detailed pics of a "real" one? The important issue would be the jets and their relation to the rim of the "can".

 

Upon further investigation I was able to extract the inner sleeve from the stove body. Strange that I wasn't able to do this at the time I received it, no matter. The inner sleeve is aluminum and the outer shell is steel. Therefore it seems that heating will cause both metals to expand, but unequally. This allows fuel to enter the space between the two cylinders (capillary action I assume) allowing fuel to enter the jets. Where do we go from here?

 

Do you have another alcohol stove?
Does it burn blue with the same fuel?

Just a guess. Look at how the two pieces fit. Are there gaps? Are there burrs? Are the parts finished and clean?

 

I tried a lower quality alcohol (50%) and got a weak blue flame. Is pure ethanol too much?



I might try a 75% mix.

 

Strange, I’ve used straight Bioflame denatured alcohol in my alcohol stoves and get blue flames.

 

Does burning the alcohol in a dish on it's own, outside the stove, make orange flames?

 

Yes, this.
Like trying the same fuel in a different stove.

 

Depends on the purity of the alcohol.

 

Yep! Isolating the trouble to the stove or the alcohol was the point of my post.

Same thing Ken had said previously; his advice was better though. Some stoves may burn poorer quality alcohol just fine, while others may not.

 

Ethanol is a much heavier fuel than methanol making it burn yellow in open burners like Trangia and the one in this discussion, that's the reason to use "methylated spirit"-ethanol mixed with some methanol.
Turm and other vaporizer burner spirit stoves doesn't need that volatile fuel to burn blue and may use pure bio ethanol without any problem.

 

@Blueflame
Here is a photo I have just taken of my stove.

I filled it with a little amount of methylated spirit, one of the Swedish brands of ”rödsprit” that is consisting of denaturated ethanol regarding the safety label.
I lit the spirit and it burned inside for about 30 seconds and a ”hiss” sound started to be heard and directly afterwards the blue flames in the holes started.

By the way, I could also separate the inner part of the stove from the outer part and they look exactly the same as yours.

Yes, trying to eliminate the cause. If it is the fuel, it will burn that way in any stove or dish.

 

I dug out my Simon stove yesterday and tried it on bio-ethanol. There were yellow tips but not that bad. I'll try it on methanol later. I also tried to take the inner sleeve out but found that is not possible as inner and outer part are rolled together to fix things.

The cardboard box it came in has "Made in Taiwan" printed on it but someone tried to hide that info with a fat marker!

I bought this stove new many years ago but hardly used it. CampinGaz stuff was cheap and popular those days.... It cost 750 Belgian Franks, late 1980s or early 1990s, I can't remember exactly.
