Yet another Landers, Frary and Clark No. 0 alcohol stove. The wick module is not fixed, I just pulled it up: Initially, the stove worked terribly, there was only one tongue of flame on on side. So I had to clean the jets on the wick module with a needle. Here are the jets: And now it works: Now it boils 500 ml of water in 5 min 40 s. On the same test stand, Primus 96 boils it in 3:20:
UPD. I measured the ethanol consumption. In 12 minutes (the time it takes to boil one liter), excluding ignition, it consumed 31 g.
