Abstract

Dependence on fossil fuels has encouraged Indonesia to develop biodiesel, in line with the mandatory B40 policy. This study examines the effect of air velocity variations on the combustion performance of B40 (40% palm biodiesel and 60% diesel) and B100 (100% palm biodiesel) fuels. Experiments were conducted using an oil burner with air velocities of 20, 35, 45, 50, and 55 m/s. The flame temperature distribution was measured at distances of 150 mm, 300 mm, 450 mm, 600 mm, 750 mm, and 900 mm from the burner nozzle using a K-type thermocouple. The results showed that the flame temperature increased with air velocity, peaked at 45 m/s, and decreased at higher velocities. The B100 fuel produced a higher flame temperature than B40, with a maximum temperature of 1052°C. The decrease in temperature above 45 m/s is due to the cooling effect of the stronger airflow, which reduces combustion efficiency. The flame temperature also tends to decrease as the distance from the burner nozzle increases, reflecting the influence of turbulence and natural cooling on heat distribution. This study highlights the importance of controlling air velocity and measurement distance to optimize flame temperature and combustion efficiency in burner systems.

Abstract

The droplet test in combustion is a widely used method for evaluating the physical properties of fuels, such as biodiesel. This examination entails depositing liquid droplets onto a surface and monitoring their properties. This study employs a semi-automatic control system in droplet testing to enhance the accuracy and efficiency of the process. The Arduino sensor system controls the heater-connected screwdriver by the droplet temperature. One button activates the Arduino sensor system to switch on and move the heater toward the droplet location. After the droplet turn into flame and shows its light intensity, the sensor captures the signals and the heater automatically reverses to maintain flame temperature. The comparison between droplet temperatures taken using manual and automatic methods were compared with 10 repetitions for each experiment. The results showed that automatic method has higher accuray result with average coefficient variation value of 4-9%, whereas the manual is 9-48%. This method is anticipated to improve the precision and efficacy of droplet testing to a fully automated control system.
