Abstract:

In this article the combustion of hydrogenated coconut oil in a commercial 50kW emulsion burner was described. Three control parameters were modified in each combustion experiment performed: fuel flow rate (C), secondary airflow rate (A), and pre-heat temperature of the coconut oil (T). The number of combustion tests was reduced by using Taguchi method. Combining Taguchi method and ANOVA analysis the optimal operation condition were stablished for the best performance combustion and the lowest pollutant emissions (CO, NOx): preheated vegetable oil at 80 °C, maximum fuel flow rate (8.17 kg·h-1) and minimum airflow rate (160 kg·h-1). Under these conditions, CO (26 ppm) and NOx (24 ppm) polluting emissions are well below the permitted minimum levels. Furthermore, a combustion efficiency of over 80% was achieved.
