Experimental Study on the Effect of Nano Additives γAl2O3 and Equivalence Ratio to Bunsen Flame Characteristic of Biodiesel from Nyamplung (Calophyllum Inophyllum)

Nano γAl2O3 has been one of the nanometal oxides that improved characteristics biodiesel. The effect nanoparticles addition on premixed flame combustion is investigated with an experiment laminar speed Calophyllum inophyllum methyl ester 30% and 70% petrodiesel mixtures, at atmospheric pressure preheated temperature T = 473K. added to CIME30 biodiesel were 0ppm, 100ppm, 200ppm, 300ppm. Experiments carried out a bunsen burner. equivalent ratio mixture between ϕ 0.67 1.17. revealed expands flammability limit increases speed. without nanoparticles, stable 0,76 -1,17. 0,67 Combustion required lot air. highest occurred 0.83. 0, 100, 200, 300 ppm 30.77, 34.50, 35.90, 38.45 cm/s respectively. higher nano concentration This occurs due catalytic its mixtures.
