trangia SVEA burner comparison with coke can burner

I made a coke can or soda can stove and wanted to compare it with a trangia SVEA swedish military burner. the coke can burner performed better in terms of POWER output but lacks the option of heat control that you get with a trangia and simmer ring.

I had a think about it when i made my coke can stove and decided to more or less copy the trangia so it's about the same height and most important of all it has the double wall design and a wick between the walls like the trangia. the wick is key.

I carry and use both, picking whichever is better for what im doing at the time: coke can burner is best for boiling up to one liter of water because it is faster than the trangia due to faster warm up and higher POWER output. If im boiling more than 1L, its very windy or if i want to simmer what im cooking then i use the trangia for its heat control with the simmer ring and its larger fuel capacity.

"Penny stoves" with no double wall are a COMPLETE WASTE OF TIME! they are very difficult to get warm and impossible to get warm if it's very windy. you need a double wall design to make it effective. A double wall design will work without a wick but will warm up faster with a wick (made out of a cotton J-cloth, old T-shirt or something or fibreglass).

Wow! Thanks, for the pseudo science no doubt prompted by a quick wiki search. I appreciate all that. I'll pass it on immediately to the design staff. The sweet spot for the trangia/svea is about 1.80 inches from the top of the burner. In the blue flame. The hottest portion is where the cooking surface is placed in our design. Perhaps they can change for you. I didn't make all this money by not knowing a bit about the design I created. Cheers.

@rcvanau your first comment: "you know nothing, i know everything"

my comment: "meh, i know something, i think they are similar for these reasons but different sizes"

your comment: "im a sarcastic asshole"

not pseudo science, i learned that in high school, not wikipedia. Im not an idiot, im an engineer.

you certainly didnt "make all this money" using charisma. Did you design this type of burner? im not sure from your first comment if you meant Trangia was yours or you based your design on it

The trangia/svea burners are more effecient than your coke can. Burning the fuel faster and producing a higher flame does not mean it produces more heat. The blue flame is what you are looking for, not a high yellow flame. You clearly don't understand fire or physics. I own a company that produces camping stoves and burners similar to this. Trangia was our model.

@rcvanau both burners produce flames that are largely yellow. The proportion of yellow to blue flame is also very similar in both burners, just the coke can burner has a larger flame and burns the fuel in a shorter time therefore is more powerfull.

It is an exothermic reaction: 2 CH3OH + 3 O2 → 2 CO2 + 4 H2O. Since the methanol is vaporised into the atmosphere, all the burners of this type will be similar, just some have more holes to let the gas out and have a lower thermal mass so are faster.

I did a similar comparison with my own trangia and a double wall beer can stove. I had similar results but you forgot to mention one important difference. The Trangia takes longer but consumes half the fuel to boil the same amount of water. This means you would only need to carry half the weight in fuel to boil the same amount of water. Depending on how much water to intend to boil, the Trangia could save you weight even though the stove itself is heavier.

@kc8ntp Yes, Penny stoves just work better than most any you can buy. I suggest getting a couple six packs of the Heinni cans as soon as you can, if you can still find them. They are discontinuing the old design with the rings (They may have stopped making them already, not sure). The can shape of the Heinni cans is ideal for the Penny Stove, and is thicker than the others too.

Lol, you have me thinking...I'm gonna see if I can find a couple six packs today. Hope I can still find them.

@Bravo21 you are so right. I use the Penny stoves and if configured right, they will burn a lot longer than these open designs. I am getting 57-minutes from 75ml of denatured alcohol; and this is without a simmer-ring. It will boil 3-cups of water in 8-minutes -- I am at 7100' ASL. I am building another Penny stove as I type this, which it is going to be a bit smaller -- around 45ml of fuel max -- and I am going to make a simmer-ring for it. This one should work great for a couple days out.

I have a Trangia stove from way back, but I now use a Penny stove I built from Heinni cans. The heinni can design allows the stoves to have a simmer ring, weigh 1/3rd of what the Svea/Trangia stoves do, are durable (Mine has a couple hundred uses) efficient and user friendly. The Svea is a decent stove, but there is better tech available, cheaper, and you have a satisfaction factor because you made it yourself.
