Attainment of complete combustion is the best strategy for mitigating the release of these emissions. This study sought to experimentally determine the effects of secondary air injection on the emission profiles of NO_x (NO & NO₂), CO and C_xH_x in a charcoal operated cookstove. Charcoal from Eucalyptus glandis was bought from Kakuzi PLC. Composites from three batches were analyzed for chemical composition and the stoichiometric air equivalent. Proximate analysis data show that the charcoal composed 58.72% ¡À 3.3% C, 15.95% ¡À 1.2% Volatile Matter, 4.69% ¡À 0.55% Moisture, 20.7% ¡À 0.8% Ash, High heat value (HHV) of 30.5 ¡À 1.1 and 29.3 ¡À 1.3 Low heat value (LHV) (MJ/kg) with a chemical formula of C₁₈H₂O and a stoichiometric air requirement of 5.28 ¡À 0.6
