Pollution When biomass, such as wood, is consumed completely in the burning process, it produces carbon dioxide (C02) and water vapor (H20) alone.Overview: Fire based solutions, such as the Rocket Stove, allow cooks to make meals when the sun isn't shining or achieve temperatures that would be difficult without expensive parabolic cookers. Heat exchanger - a tubular metal shield that forces hot gases from the chimney to pass over the sides of the cooking vessel.Chimney - a metal box (such as a 5-gallon tin can) or pipe standing vertically and supporting the cooking vessel.Fuel shelf - holds the fuel clear of the bottom of the magazine to allow air to flow underneath.Fuel magazine - a short length of steel or ceramic pipe fitted horizontally into the base of the chimney.The Rocket stove's main components are as follows: The Justa Stove, for example, is a cousin of the rocket stove adapted for indoor use and family cooking needs.Ī Rocket stove made from a barrel in Bolivia This attention has resulted in a number of adaptations intended to improve convenience and safety, and thus the size of the target audience. As such, sufficient fuel for cooking tasks can be gathered in less time, without the benefit of tools, and ideally without the destruction of forested areas.īecause these qualities improve local air quality, and discourage deforestation, the rocket stove has attracted the attention of a number of Appropriate Technology concerns, which have deployed it in numerous third-world locales (notably, the Rwandan refugee camps). Furthermore, the design of the stove requires small diameter lengths of wood, which can generally be satisfied with small branches. Rocket Stoves operates roughly twice as efficiently, and substantially more cleanly, than the open fire cooking methods still used in many areas of the world. Baking is done inside the inner drum-in a sealed compartment within the chimney, above the firebox. The outer drum is split open to create an insulated chimney space between the two drums and to allow for a doorway. Rocket stoves used in conjunction with hayboxes can save enormous amounts of fuel, cooking complete meals while using very few resources.Ī related design, the Rocket Bread Oven, is constructed using two 55 gallon drums, one inside the other. The low-mass stove body and insulated chimney ensure that the heat goes into the cooking pot, not into the stove. The pieces of wood or other material burn at their tips, increasing combustion efficiency, creating a very hot fire, and eliminating smoke. Rocket Stoves use branches, twigs, small wood scraps, or just about any small combustible material. A skirt around the pot will help hold heat in, increasing the efficiency. Cooking is done on top of a short insulated chimney. These are low-mass stoves designed to burn small pieces of wood very efficiently. It is easy to construct, with low-cost materials. The Rocket Stove, a popular variety of improved combustion stoves, is an integral part of the Integrated Cooking Method.
