A rocket stove is an efficient and hot burning stove using small-diameter wood fuel. Fuel is burned in a simple combustion chamber containing an insulated vertical chimney, which ensures almost complete combustion prior to the flames reaching the cooking surface. Rocket stove designs are most often used for

s for cooking but the design is also used for large, fixed stoves in institutions, and to make rocket mass heaters for heating. In field tests in India, rocket stoves used 18 to 35 percent less fuel, compared to the traditional stoves, and reduced fuel used 39-47 percent, compared to the simple, traditional, open, three-stone fire.

History

A precursor to the rocket stove was the

Argand lamp The Argand lamp is a type of oil lamp invented in 1780 by Aimé Argand. Its output is 6 to 10 candelas, brighter than that of earlier lamps. Its more complete combustion of the candle wick and oil than in other lamps required much less frequent ...

, which introduced a glass chimney above the flame to increase air-flow. As well as being used for lighting, this design was also used for cooking and for heating water due to its "affording much the strongest heat without smoke." Larry Winiarski, Technical Director of Aprovecho, began developing the rocket stove in 1980 based on a VITA stove, designed by Sam Baldwin, and rediscovered the principles of the systems developed by the Romans in

Efficiency

Many developing countries use traditional wood fuel stoves without proper ventilation, which produces indoor concentrations of smoke particles "typically 10 to 100 times the long-term levels recommended by the

." Chronic exposure to these particles are linked with disease. Rocket stoves are better at combusting the fuel, thus using less fuel and producing less smoke,

In rural Kenya, a comparison of traditional three-stone stoves and rocket mud stoves (RMS) showed that RMS use resulted in a 33% reduction of carbon monoxide production in the kitchen and a 42% reduction in "personal" carbon monoxide production, which was measured with data loggers placed on clothing.
