    I thought I would post these pictures of Dragonfly simmering. I let it stay that way [Edit: with the pot on in the windless garage] for over 20 minutes, and it did not deteriorate. This is at its lowest setting for simmer, and the flame does not produce any fume or soot. It burns efficiently in the manner of the Perfection kerosene heaters of yesteryear. I think this is unique to Dragonfly, to be able to sustain simmering in the orange flame that is clean.

    That is interesting. I don't own any modern stoves at the moment. It seems like there are pros and cons with every model but good simmering is very important to me, I don't want to burn my water!

    I wish PRIMUS OPTIMUS MSR ETC could get together for a big group hug and come out with one stove to rule them all.

    I usually keep mine half blue half yellow.
    Seemed low enough for me.
    Any troubles with sooting or flareing when turned back up to full steam??

    Cheers

    No, not at all. It is a seemless transition from minimum to maximum. I am quite pleased.

    Hey, B2M,

    Seeing your post made me think about my own Dragonfly, and also my beloved Firefly.

    Here is the simmering flame on my Dragonfly, using Coleman fuel.

    And, here's the simmering flame on that wonderful, old Firefly, which is also burning Coleman fuel. It doesn't get much better than this, me thinks! ;) 8)

    (Ooooops.... the file was too large! Sorry about that! I'll come back and add it later, when I can resize that FF photo.) Talk to you later, my Friend, and God Bless!

    Every Good Wish,
    Doc

    hi all; the steady long burning yellow flame is testament to the good design and efficiency of generation after all the next step from yellow is soot & smoke. the most efficient flame is all blue, for a stove to burn yellow for some time and show no sign of fouling is impressive indeed. i would not recommend this for most stoves unless you wish a carbon clogged stove. mike...

    Mines different again.
    Seems slow to boil compared to the specs but do me.
    Forgret what I did but I think I stuffed it. never mind. It'll do just fine as it is.
    Good flame spread on fry pan when cranked up a bit.

    Interesting, indeed, to see how three individual Dragonfly from the same manufacturer all behave differently! It reminds me how individual rifles of the same manufacture print differently on the paper, too.

    Wow, I can only get this blue simmer on Dragonfly by using alcohol, white gas or gas butane-propane.
    Definitely, I should get those AvTur/Jet A1.

    Not tried kero for simmer but white gas will stay clean blue down as low as all these. I wonder if there are impurities in the kero of the first post. That could explain yellow and minimal soot. Sulphur is the most common issue
