Something wrong with my trangia

[Povarian]

I just received my swedish stainless steel trangia mess kit from Tommy, and I'm wondering what's going on...

Three brews mashed in it, and there's been NO sootiness - and I'm using the dyed meths too. I thought I was supposed to get black over everything, and that's why people are recommending the dyeless stuff. Any explanations?

Not that I'm complaiing though.

Any chance your meths may have been contaminated with a little water? That would cut out a lot of the sootiness.

I wouldn't have thought so - straight out of a homebase bottle into a trangia fuel bottle and then into the burner. No visible signs of water - i.e. layer separation. I was using it just above a stream for the brews, so the air was slightly more humid than usual. Most of the stram bed is dry now, but I chose the spot where it emerges from the underground run to the surface.

As an aside - how much would water contamination affect the burner efficiency?

i use a form of alchol called methylized alcohol, which is a 85% mixure and also has a dye in it. which means it has 15% water in it. I have never seen any soot in trangia or similar stoves ! The burner still has enough power to cook my food and water with.

I suppose -any- water will affect the burner efficiency to some degree. To be honest though, I've never really noticed much of a difference when I've added 10% water by volume to my meths.

My uncle had a Trans Am (KITT style) which had twin turbos and hydro injection. This involved adding water into the combustion mixture to aid cooling from the heat of the turbos, and actually increased the combustion efficiency in the same was an intercooler does by cooling the air and making it more dense. Interesting to know how it would effect trangias though.

Not to mention the umpteen ww2 fighters that had either water or steam injection for go faster ability !

the water injection in an engine cools the air/fuel mix making it denser. this allows more fuel to reach the combustion chamber producing more power in the engine.

in a trangia the fuel is unpressureised so it's not goingto have the same effect. time for an experiment. i'll get back to you on this.
