The use of inefficient cooking stoves puts great pressure on the forests, as well as poorly
secured cookers pose health risks to the users. Improving the energy efficiency of cookstoves reduces
biomass consumption and thus the anthropogenic pressure on forests. This work aims to identify the
best charcoal cooking stove(s) in terms of energy performance, safety and sustainability. The
proposed approach combines the combined study of the energy performance, safety and durability of
charcoal cooking cookers. A representative sample of five types of charcoal stoves commonly used
in Benin is tested according to the requirements of the ISO 19867 standard. These are the square
cooking stove, the circular cooking stove, the clay cooking stove, the rim cooking stove and the
Nansu cooking stove. The results show two stoves with the best performance: The Nansu stove with
a total energy efficiency of 27.44% and an output of 0.9 kW and the clay stove with a total energy
efficiency of 25.11% and an output of 0.71 kW. These two stoves are made of clay, while the other
three are made of metal. The clay stove offers the best safety with an overall average rating of 71.5
compared to 66.5 for the Nansu stove. The Nansu stove has better durability than the clay stove. This
study thus contributes to the preservation of the environment and health through the recommendation
of efficient, safe and durable charcoal cookers to be promoted. |
