R&D: Wood-Burning Stoves for TAPS

Amazima Ministries serves communities in and around Jinja, Uganda by providing education for children and youth, medical care, vocational training, and discipleship for women, children, & families.

Everyday the primary school prepares lunch for hundreds of children from scratch. Firewood is used to cook the meals. Typical wood-fired stoves are inefficient and fill the kitchen with smoke and soot. This results in higher operating costs for the ministry, contributes to deforestation, and creates a harmful work environment for the cooks.

EMI’s R&D team developed a more efficient wood-burning stove, using materials from a nearby vermiculite mine. When operated correctly, the redesigned stove lowers wood fuel consumption, shortens cook times, and keeps smoke out of the kitchen. 

Prototype and data collection during stove R&D. The materials of construction and geometry of the stove help achieve near complete combustion. This reduces smoke (unburnt fuel) and keeps heat and hot gases inside the stove near the pot.
