Designed to increase fuel efficiency without increasing harmful emissions, rocket stoves are helping people become more self-sufficient, slowing climate change, and saving lives in developing countries where fuelwood is scarce and traditional open fires are polluting indoor air.
An insulated rocket elbow, formed of a horizontal fuel chamber that fits into a vertical combustion chamber (also referred to as a “chimney”). There’s a stove body that surrounds the elbow, made of sheet metal or some other inexpensive material, with a small opening.
A fuel grate is placed inside the fuel chamber, on which the fuel wood rests. Above is a pot skirt, a sheet metal shield that surrounds the cooking vessel, creating a gap, to ensure that more heat from the flue gases enters the vessel.
