Analysis of the Effect of Air Flow Rate and Waste Cooking Oil on Furnace Efficiency

Using waste cooking oil (WCO) as an alternative fuel can reduce dependence on fossil fuels and address the problem of waste oil. This study aims to analyze the effect of variations in air flow rate and WCO on the combustion characteristics and efficiency furnace. The combustion process was carried out by varying the fuel and airflow rates of the furnace. The experiments included measuring the flame temperature, boiling water tests, and measuring the efficiency of heat absorption by water in the pan. The results showed that the highest combustion temperature of 925.55℃ was achieved at an airflow rate of 10.5 m3/hour with a fuel flow rate of 10.5 x 10-4 m3/hour. This comparison also produced the fastest water boiling time of 2 minutes with a heat absorption efficiency by water in the pan of 33.37%. The highest heat absorption efficiency by water in the pan was obtained at a fuel flow rate of 6 x 10-4 m3/hour with an airflow rate of 6 m3/hour of 42.14%. These results demonstrate the potential of WCO as an alternative fuel for efficient household combustion appliances, with the right air supply to achieve optimal combustion.
