160 grams of charcoal boils and simmers 5 liters/CF04 Stove
Lanny Henson www.lanny.us 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.

CO/CO2 Ratio in the Charcoal Stoves Tested at Aprovecho (pdf)
Dean Still, Aprovecho Research Center, June 23, 2006
The following graph plots the levels of CO and CO2 during one test each of the charcoal burning rocket stove and Jiko-type charcoal stove from Ghana. A higher level of CO2 suggests a higher burn rate of fuel.
It can be seen that even though the CO level for the rocket drops below 10 ppm, the CO2 level remains high suggesting a high firepower continues. The Ghana charcoal stove has a lower level of CO2 with a considerably higher level of CO.

Comparing the Charcoal Burning Rocket and Jiko Stoves (pdf)
Dean Still and Nordica MacCarty, Aprovecho Research Center, June 22nd, 2006
The charcoal Rocket Stove was compared to the Jiko-type charcoal stove sent from Ghana. 600 grams of Kingsford charcoal was placed in the stoves under the Aprovecho emissions hood. One test was performed on each stove for preliminary studies. The stoves are compared in the following graph for carbon monoxide emissions during a cooking task (to boil 5L of water and simmer 30 minutes).
