Rocket stoves are small efficient stoves that can produce a hot flame with only a few small pieces of wood. The reason it is called a rocket stove is because when wood is added to the fire the flames create an internal draft. As the draft is created, the fire begins to produce a jet of fire coming through the stove pipe. The stove flame eventually becomes so hot that it produces very little smoke. The stove should be able to produce a hot continuous flame that will lick the bottom surface of a pot or pan placed on top of the stove.
These stoves were created out of necessity in third world countries to cook small meals and have recently become more popular as a do-it-yourself camping stove. A rocket stove is usually made from readily available materials that can be recycled for reuse. To make a large stove, it is not unusual for the outside shell of the stove to be made from an old propane tank, Freon tank, or air compressor tank. To complete the following instructions for making a rocket stove, experience in welding and metalworking is needed as this project requires a great deal of it.
Step 1: Materials
Changes may be made to the materials in the schematic according to personal preference or based on availability of materials. Materials for fabricating stove legs are not present because many different configurations may be acceptable. Any design may be accepted for personal preference, as long as it is able to support at least 100lbs and withstand high temperatures for this model.
