Alcohol Mega-Stove

This stove was bult using a 9.2oz aluminum mousse container. Width is 2 5/8 OD and almost 3.5" tall. I was looking for a stove to boil at least 32oz of water, and came up with this. However when the stove is going, and i put the pot of water on top, shortly after it goes out. eventhough there is plenty of alcohol??

thanks guys for the information. I have put this stove "on the back-burner" (pun) for now. Working on my jellystove. video will be posted up soon on it.

To try and fix this one, try JB weld around rim to isolate pot from stove. Also, try 3 or 4 steel or copper wires through jets into stove down to bottom. Try to get more heat into the alcohol.

To fix the design, it looks like the jets are too close to rim. Drop them down a bit.

not sure what you mean "around rim"? would this be to isolate cold h2o wicking to stove? took BrokenAero's idea,drilled 16 holes 1" frm top; which is .5" below 32 holes. Stove brings water to a boil, but it burns full bloom 1st, and then flame goes to a simmer, and eventually boils H2O. I'll seal 32 holes & drill another 16 holes staggered below new 16 holes. confused? hope not. LOL. i like the idea of metal wires down into alcohol, understood concept. will try if mod listed above no worky. ;)

If you use fiberglass cloth held tightly to the wall to wick the fuel up to the holes, you will greatly increase the performance of your stove because the gap between the high and low temperatures will be minimized. Also, the more holes you have in a row, the more you reduce the driving heat wattage because you are reducing the cross sectional area of the aluminum conductor.

Thanks. picked up some fiberglass cloth frm lowes. will try on another stove as this one is jb welded> inner/outer wall already.

What if you add a couple of oz's of Perlite to the stove? That might hold the heat better and keep the fuel evaporating? That was going to be my suggestion.

[ez2curanut]

interesting... i can try the perlite. where do you get that perlite from? I modded this stove with another 12 holes 1/4" below 1st row.

We should wait to see what BrokenAero has to say. If it will not help, BrokenAero will be able to tell us why. I used it in the pop can project because the directions I was following suggested it. However ... it's purpose was to keep the fuel from boiling too fast!

It is very light weight stuff that looks like Styrofoam (white). They sell it at garden supply stores and use it for potted plants. It is a type of heat treated rock ... I think.

The answer is really simple and has already been posted here - the jets are too high. The other bud stove in your video should be able to boil 32oz with no trouble. This is one of those designs where more is not necessarily better.

He's recommending you create a tripod with JB weld to reduce transfer to the pot. That won't be necessary once you make the other modifications. JB weld isn't recommended for use in areas of potential flame temps. Instead you can make three triangular point cuts in the cans before you mate them. But know that you will start to get flame from the inside of the can, and your flame plume may become excessive and innefficient.

[BrokenAeroVT]

You already have plenty of high transfer rate metal conductor. Take advantage of it. No need for extra copper wire. Lowering and spacing the holes will do wonders without the extra weight, & bringing the fuel up to the holes with wick will have the most profound effect in increasing the heat flow.

Around rim refers to top of stove where pot touches. Should insulate stove from cold pot. Some use a wire shaped like a V to reduce contact area. Put V between stove and pot.
