This study aimed to reduce the emission of a boiler using waste cooking oil biodiesel blended with different nanoparticles. The nanoparticles used in this study were cerium oxide and gamma alumina (CeO2 and Al2O3) in three concentrations (25, 50 and 100 ppm) blended with waste cooking oil (WCO) biodiesel. The effect of adding nanoparticles to the neat biodiesel was evaluated in a combustion system to reduce its emissions. For the experiments, a semi-industrial boiler and gas analyzer (Testo 350z) were used to measure the amount of exhaust gas (CO, CO2 and NOX). Experiments show that BDCe100 (Biodiesel containing 100 ppm cerium oxide) has the least CO and NOx emission in comparison with other samples. Nanoparticles play the role of catalysts in the combustion process resulting in more complete combustion.
