Well, yeah, but I wonder if there's any other kind of fuel besides alcohol for alcohol stoves?
No! Absolutely
do not burn any other kind of fuel in a mass burn stove like a Trangia or pop can stove (same principle). The same thing that makes them able to burn a pool of fuel...i.e. low heat value, lower temperature and higher flash point... makes them incredible dangerous to burn with a fuel that burns hotter with a higher fuel value and lower flash point. Think BOOOM! Putting white gas in a pop can stove makes for a very hot, very unpredictable flame and the potential for a disaster is just too high. Stick with alcohol if you are going to use these kinds of stoves.
