We present in this paper the results of experimental and numerical study of the thermal performances of a cook stove prototype intended for the parboiling of paddy rice. Thus, the experimental results show that the optimal mass of husk rice is M = 7.15 kg for a good combustion within the combustion chamber and got a maximum temperature at the level of the burners surface. This temperature is T_cu1=304.78°C. The circulating air flow rate by forced convection is Q_m = 0.09112 m^-3·s^-1. The vertical side walls temperature is T_ple = 140.6°C and the water temperature and vapor is about 144.6°C in the stockpot. The gas combustion is composed of carbon dioxide (CO₂), carbon monoxide (CO), methane (CH₄) and the ratio of hydrogen to nitrogen (H₂/N₂). The results from the numerical modeling indicate T_cu1=307.8°C, T_ple = 144.55°C and a Q_m = 0.09258 m^-3.s^-1. The average thermal efficiency of the cookstove is η = 46.6% and the power developed by the cookstove is about ≈6 kW. Despite the heat losses, the cookstove remains interesting for paddy rice parboiling activities.
