Laboratory Testing of Rocket Stoves of Various Capacities As Compared to the Three Stone Fire
Dean Still, Nordica MacCarty, Aprovecho Research Center, April 2007

In an effort to understand the relationship between stove capacity and fuel use and emissions the performance of three sizes of rocket stoves were compared.

The stoves were tested with the 2003 UCB revised Water Boiling Test. Pots that were integral to the stoves were used without a lid. Kiln dried Douglas fir at approximately 10% moisture content was burned in all tests. Only one test was performed on the household stoves. Therefore, results are not statistically valid but should be useful for general comparison. The [attached] graphs show results from three Rocket type stoves as compared to a carefully tended Three Stone Fire.

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.
