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

Abstract

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.
