Millet stalks are used as fuel in pottering crafting in Africa. A study was conducted to characterize the gaseous species produced during the reductive and oxidative combustion of millet stalks. The experiment was carried out on temperature ranging from 800-1000°C, using the tubular furnace, coupled with two gas analyzers i.e. Analyzer Fourier Transforms Infrared (FTIR) analyzer and a non-dispersive infrared (NDIR) as experimental apparatus. The gaseous products analyzed are i.e. CO, CO2, CH4, C3H8, C2H4, C2H2, C6H6, HCN, N2O, NO, NO2 and NH3. The results show that, in reducing conditions, the levels of carbon monoxide (CO), methane (CH4) and acetylene (C2H2) are increasing functions of temperature, while emissions of CO and benzene (C6H6) decrease as the temperature increases. Emissions of other compounds were remained relatively stable. Reductive combustion produced various compounds like CO2, CO, N etc. while oxidative combustion produced compounds like light while oxidative combustion produced compounds like light was found about 15%.
