To improve the efficiency of the Simple Camp Fire Stove I added a third piece, a sleeve to focus the heat on onto the pot. The exhaust was a lot cooler and slower so I could tell that more heat was going into the pot it still took 12 min to boil 6 quarts. Next time I will open up the gaps at the top tabs to allow a little more flow. At one point I was adding wood to the stove in 3 places. I like the sleeve so now I need to do something about the fire. The combustion area is too large. It is about 11" dia and about 6" tall. How would we improve the burn with only 1 more simple piece, maybe 2 ?
