Kenya Ceramic Jinko - an improved cooking stove for Africa.
Background
Traditional cooking methods in Kenya used a pot on a clay fireplace or a sheet metal stove - jinko - which consumes much wood, leading to degradation of forests. Collecting firewood is a major imposition on women. And incomplete combustion (particularly indoors) gives rise to many respiratory illnesses.
Thus, there was a need for a better cooking stove.
Performance
The Kenya Ceramic Jinko uses coke, and reduces fuel by 30-50%. The ceramic liner reflects radiant heat back to the fire, increasing combustion temperature and giving more complete combustion of the carbon. The fumes are much reduced.
