Re: More Data for a Wide Pot on 08/23/2013 13:22:42 MDT Print View

Test #1: Wide Pot, 16 ounces of water

Elevation - 7,400'
Boiling Point of Water - ~195°F
Air Temp - 70°F
Wind - negligible
Water Temp - 45°F
Water Volume - 16 fluid ounces

Caldera Cone for a Vargo Ti 1.3L pot, 5.75" in diameter, and a 12-10 stove.
The lid is insulated with a single layer of aluminized 1/4" bubble wrap.

Sunnyside "Marine Stove Fuel", Product# 834G1, 52% Methanol and 43% Ethanol, per the MSDS

Three sessions, topping off the stove for sessions #2 and #3.

Boil time was 8, 9, and 7 minutes, determined by an instant read thermometer and observation.

Fuel consumption averaged 11 grams per boil, 5.5 grams per cup.

So, pretty consistent with what is posted above.


I was curious of the concept of "volume efficiency", so..

Test #2: Wide Pot, 32 ounces of water

Elevation - 7,400'
Boiling Point of Water - ~195°F
Air Temp - 70°F to 75°F over the course of the testing
Wind - negligible
Water Temp - 45°F
Water Volume - 32 fluid ounces

Sunnyside "Marine Stove Fuel", Product# 834G1, 52% Methanol and 43% Ethanol, per the MSDS

Three sessions, topping off the stove for sessions #2 and #3.

Boil time was 14, 16, and 16 minutes, determined by an instant read thermometer and observation.

Fuel consumption averaged 24 grams per boil, 6 grams per cup.

Also consistent with the posts above, so not much gained here.



Given field variables like centering the pot over the stove, wind, water temps, approximate measures, noticing when the water is boiling, etc. I'd say pot size doesn't make much of a difference with a Caldera Cone.

For solo trips I'll stick with the Keg-H.


So, Eric B., where is that Sidewinder data you where eluding to?

I have never needed more than 0.8 fl oz to boil up to 20 fl oz of water. I do have the Fosters, not the Heinie.

I am getting a much quicker boil with the Staryte burner. Really like being able to seal off the remaining fuel in the stove also.

Katharina,
How much fuel are you using to boil 2 cups of water?
Starting and ending temperatures would be good to know.

Just curious...

Well, I should have known that details matter here.
Let me try again tonight. Hard to tell how much fuel because there was some left over and it is not visible. I will weigh stuff for you.
A little later.

An attempt at something a little more precise.

Room temperature 71.
Just about Sea Level, maybe 200 feet up.
No wind.

Using Heineken pot, Caldera cone, Starlyte burner ( the regular one, not the modified one meant for this set up).
On a wooden cutting board with a sheet of aluminum foil on top.
2 cups of water; temperature started at 64. Came to a rolling boil ( did not stick thermometer in..)
In 8 minutes.

Used 12 grams of Klean Strip denatured alcohol.

Burned my finger once. Not badly.

Thanks.

Sorry about the finger. But it was for a good cause.

Seems like 6 grams per cup is a pretty typical number.

I pulled out the Ti-Tri sidewinder with my Evernew 1300 ml pot and got:

Air temp: 68.5
Water temp 49.something (not quite 50)
Water: 16 oz
Elevation: 8640'
Boil time: 10.25 minutes
Fuel consumption: just over .5 oz
Fuel: Klean-Strip Green (I use Evernew in the field but not for testing stoves)
Stove: 12-10

I was going to test the Keg-H right after but had to deal with a work issue. I'll try again to compare the 2 directly again tomorrow.

I take the Keg-H for short trips but the Ti-Tri for longer trips when burning wood is possible. I'll still take the 12-10 stove and some alcohol but a lot less if I know I can burn wood. That alone makes it worth taking other stove system.

I ordered a StarLyte last week and am looking forward to trying it out with both setups.

"(I use Evernew in the field but not for testing stoves)"

I don't think that is what you meant.

Everclear, the best fuel he Everknew. Multi Purpose is good.
