This final part of my canister stove series is more of a technical addendum that addresses the canister stove's interaction between propane and cold temperatures.
Why isn't propane very useful in an upright canister stove if you want to use the entire canister at low temperatures?
Given all the ideas in the previous three parts of this series, one has to ask what limitations restrict the use of upright canisters at below-freezing temperatures. It turns out there some significant restrictions. I took three different fuel mixtures and ran them through the spreadsheet used in the article The Effect of Cold on Gas Canisters by Stuart Robb and Roger Caffin to see what would happen to the propane concentration as the gas was used up. The results were a bit surprising.
