Our plans about building a sustainable high efficiency wood burning stove design led us to the folks that designed the Rocket Stove. You can find out about this stove design at http://www.rocketstove.org/. They offer many designs from the basic brick stove we have designed to the barrel stove we have built in San Antonio Agua Caliente Guatemala outside of Antigua Guatemala. Our vision was to find used materials around Antigua at the market in order to be able to build this barrel version of the Rocket Stove.
Sustainable Guatemala Wood Burning Stove the idea was to find used materials and Sustainable materials to build our Guatemala wood stove from. This is a popular idea about being or using Sustainable materials for a wood stove design. So we used junk materials we found around Antigua Guatemala and area. Most of the materials are not Sustainable, only the insulation between the barrel and the flue are Volcanic Ash which Guatemala has an abundance of.
A rocket stove is an efficient cooking stove using small diameter wood fuel which is burned in a simple high-temperature combustion chamber containing an insulated vertical chimney which ensures complete combustion prior to the flames reaching the cooking surface. The principles were described by Dr. Larry Winiarski from Aprovecho in 1982 and stoves based on this design won Ashden Awards in both 2005 and 2006. Interest in rocket stoves has led to the development of rocket mass heaters and other innovations.
The rocket stove was originally developed for cooking, where a relatively small amount of continuous heat is applied to the bottom and sides of a cooking pot. Stoves can be constructed from brick, recycled steel cans, or steel sheet metal, or can be purchased.
Although rocket stoves are found more commonly in third world countries where wood fuel sources are more scarce, they have seen in recent years increased use in developed countries, such as the United States. Some are small for portability, with insulation inside a double-walled design and a chamber for partial biomass gasification and additional mixing to increase BTU production and to provide a cleaner, more complete burn. The advantage of rocket stoves is the very little fuel they need, such as wood and dry weeds, to be able to cook a whole meal with it, keeping the air cleaner with less hydrocarbons and carbon monoxide.
