- The utilization of biodiesel in boiler has a great benefit due to lower exhaust emissions. The combustion system tends to be simpler than compression ignition as performed in diesel engine. This study was carried out experimentally in a fire tube boiler, with heat input rate of 60.000 kCal/hr and 3 bars of pressure by using palm biodiesel as a fuel. The mixture was varied in 0, 10, 15 and 20% of biodiesel in blends with petroleum diesel (B0, B10, B15, and B20). The experimental research was validated with the CFD simulation by using ANSYS FLUENT CFD package. CFD analysis can provide a better understanding of the combustion process in boiler. The result shows that the use of biodiesel decreased the gases emission with the increasing value of biodiesel in blends. The lowest gases emissions are about 2,78 ppm (NO2); 14,00 ppm (SO2) and 7,65 % v/v (CO2) which is found in the 20% of biodiesel in fuel (B20).
