My project du jour. I'm trying to optimize my esbit fuel consumption and to assemble a simple, light, and efficient system to boil water and nothing else. This is going to be an ongoing project over the next few months and I'll update this thread as I go. As always, your input is appreciated.
With my current set up, I can boil 16 ozs of water and warm up another 8ozs just enough for a lousy cup of tepid coffee in the morning. Ideally, I'd like to be able to boil 32oz of 40* water with one tablet. The boiling temperature is overshooting my needs as I'm not trying to sanitize the water so in the field I only need it to reach 150*-175*F (dependent on what I'm trying to rehydrate) and my cozy will be able to sustain that temperature with < 10* drop over 10 minutes. At a minimum, if the 32oz with one tablet is undoable, I'd at least like to enjoy a relatively hot cup of coffee in the morning setting an alternative goal of 24ozs on one tablet.
My tentative plan is to acquire or MYOG the few systems I'm aware of who specialize in optimizing the Esbit fuel consumption (Flat Cat & Caldera Cone.) My current system is < 6oz for SP 700ml pot, cozy, stove, ti spork, windscreen, heat shield, and ti wing. A singe Esbit tablet in its package is .5 oz. It would be pointless for me to adopt a more efficient system which would add several ozs to the basic set up.
My ti wing is weight friendly at .5oz but the flame pattern over performs for the first few minutes and I lose precious heat. One solution is to buy a wider pot but I like how the narrow pot fits in my pack so I'm trying to make this one work. I'll eventually buy a wider pot to see how that affects the performance.
So I start my journey with my first failed project (don't try this one at home kids)-
The general theory was to cut the bottom out of a fancy feast can and fill the sides with holes. By eyeing it, it seemed that the distance from the tablet to the pot was similar to what it was with the tri wing. The tri wing (my current set up) with windscreen and heat shield will achieve a boil 10-10.5 minutes. The Fancy feast project was still limping along at 15 minutes with no end in sight. I was unwilling to pursue it any further as the 10 minute boil time is at the threshold of my patience in the first place.
This was the worst of all worlds as the fuel was nearly expired at 15 minutes. This project would not work for simmering either. I found an old thread where Craig W. used a fancy feast can and cut larger holes into the side. I'll try that tomorrow and see how it goes.
So here's my failed project in all its glory:
To be continued....
