Abstract
Improved charcoal cookstoves are being produced indiscriminately by unlicensed local craftspeople, and their use is expanding quickly in Sierra Leone. There have not been any comprehensive or in-depth analyses of efficiency or charcoal savings on Wonder stoves and Metal stoves. In this study, the performance of two improved charcoal cookstoves —the Wonder stove and the Metal stove—was assessed. To conduct efficiency and charcoal-saving analyses, a set of charcoals from the Abura tree (mitragyna cilliata) and another set from assorted trees: Mango tree (Mangifera indica) and Matchstick tree (Aechmea gamosepala) were prepared. When Abura charcoal and other types of charcoal (assorted) were to test the efficiency of the stoves, the results obtained for the Wonder stove showed average efficiencies of 19.67% and 14.68%, respectively, while those for the Metal stove showed efficiencies of 17.79% and 14.75%. When burned charcoals were compared at the high-power phase cold start in both stoves, the Wonder stove saved 54.21% of the charcoal with a corresponding time of 4.42 minutes, while the Metal stove saved 1.40% of the charcoal with a similar time of 4.34 minutes.
