Wonder Institutional Rocket Stove
Wonder Institutional Rocket Stove

The stove is designed for large-scale cooking that is currently done over the traditional 3 stone fire. The portable institutional rocket stove features a small removable combustion chamber unit made from ceramic slabs and mild steel. The combustion chamber has both primary and secondary air inlets and is contained in a round metal cylinder. At the top, a double skirt around the cooking pot forces the gases from the combustion to scrape against the side of the pot, it then transfers the heat to the pot enhancing the efficiency of the stove. Different sizes of the combustion chamber and other parts of the stove are variable depending on the size of the pot, ranging from 50 litres, 75 litres and 100 litres. The fuel magazine is at the front of the stove with a shelf that supports the firewood, to the sides of the fuel magazine there are primary air inlets, firewood is continually fed and freely burns in the fire chamber, and the chimney is attached to the skirt for excess smoke to be removed from the cooking area. The stove is designed to accommodate round bottom pots, which are made by local artisans in West Africa.
