160 grams of charcoal boils and simmers 5 liters/CF04 Stove
Lanny Henson July 2, 2006

The CF04 Stove boiled and simmered 5 liters using only 160gr of charcoal and wood.

After several modifications to 4 different prototypes, it only took 150 gr of lump charcoal with 11% moisture and 10gr of wood to boil 5 liters of 83 degF/28.3 degC water in 45 min. That is 32 grams per liter to boil and simmer. At 1 hour after boiling the water was still simmering at 100 degC and after 2 hours the water was 205degF/96 degC. At this point I shut the air control and capped the pot module to stop the airflow and retain heat.

At 3 hours the water temp was 190 degF/87.8 degC and was 178 degF/ 81 degC at 4 hours.

This modular stove is built from used metal containers.

It has a center fire burner module, a sunken 8-liter pot module, and an insulated/ chip drying top cap.
The burner and is made from an institutional food can. It takes all the ware and stress from the fire protecting the rest of the stove body.They are easy to build and can act as fuel cartridges to store fuel for quick and easy use.
The burner module, under development, adds secondary combustion air to the top of the burner.
