Realization and Experimental Study of a Hybrid Cooker (Solar-Biomass) in a Sahelian Climate

---

Résumé

Solar cookers are devices that allow cooking by using free solar energy. However, they can’t
operate during cloudy periods or at night. A hybrid cooker (solar-biomass) is an alternative that
uses an endogenous and renewable energy source for ecological and economical cooking. In this
work, the performances of a hybrid cooker (solar-biomass) are evaluated. The experimental
results obtained indicate that the absorber plate reached a maximum temperature of 121.60 °C.
Moreover, the maximum power of the cooker was 78.47 W with an efficiency of 29 % in solar
mode and 28.4% in biomass mode. The first and second figures of merit parameters performed are
0.1043 and 0.2732 respectively. The results obtained are conclusive in both solar and biomass
mode.
