Jeff, are you still using this design? This is my second year evaporating on an institutional rocket stove with 60L pot. I've rebuilt the burn chamber a couple times with steel and I'm just starting to test mixtures of insulated castable refractory. I'm also looking to redesign for next year to increase the evaporation rate which for me is 2.5gal/hr. The 60L pot holds over 10 gallons but there isn't enough surface area. I'm curious to hear if you have any updates and what you've learned since this build.
Thanks
