This study investigated the emissions of a semi-industrial boiler using waste cooking oil biodiesel blended with different nanoparticles. The addition of CeO2 and Co3O4 showed a synergistic effect, with the B-Ce-Co-Al50 fuel sample exhibiting the lowest CO emission and the B-Ce-Co100 fuel sample showing the lowest NOX emission.
In the present study, the emission of a semi-industrial boiler has been investigated using the waste cooking oil biodiesel (WCO) blended with the different nanoparticles, including CeO2 , Al2O3 , and Co3O4. The nanoparticles were blended to the WCO biodiesel in three different concentrations (25, 50, and 100 ppmw), considering the different combinations of single, binary, and ternary compounds. The results confirmed that there is a synergistic effect by the addition of CeO2 , and Co3O4. It was also found that the application of B-Ce-Co-Al50 fuel sample (WCO biodiesel containing 50 ppm cerium oxide, cobalt oxide, and aluminum oxide) leads to the lowest value of CO emission. The CO emission for this fuel sample was 74%, and 43% lower compared to the neat diesel, and WCO biodiesel, respectively. The lowest flame temperature and the lowest NOX emission was observed for B-Ce-Co100 fuel sample (WCO biodiesel containing 100 ppm cerium oxide and cobalt oxide). The NOX emission for this fuel sample was 10%, and 39% lower compared to the diesel, and the WCO biodiesel, respectively. (C) 2021 Institution of Chemical Engineers. Published by Elsevier B.V.
