Study on the performance of palm methyl ester in a combustion system

Nowadays, the world is adversely affected by the rapid growth of various industries which use fossil diesel fuel as a main source to power their respective industries. As such, this phenomenon has contributed to environmental pollution apart from these natural resources are increasingly reduced thus resulting in price increments. However, biodiesel fuel has recognized by many researcher as a potential replacement of fossil fuel. A study was conducted to investigate the performance of alternative energy sources that are environmentally friendly and renewable such as palm biodiesel. Therefore, this project presents an investigation on the combustion performance of Palm Methyl Ester (PME) which also known as Palm Biodiesel in an oil burner system. Several Carotino’s palm biodiesel blends (B10, B20, and B40) also have been made by blended with Conventional Diesel Fuel (CDF). Examination of the fuel properties for each blends including CDF and PME have been carried out. The performance of the fuels have been studied based on its wall temperature profile and gas emissions generated such as nitrogen oxides (NOx) and carbon monoxide (CO). The test fuels have been burned in the oil burner combustion chamber at different equivalent ratios and using three different oil burner nozzles (1.25, 1.50 and 1.75 USgal/h). From the test, PME is the lowest emission production compared to CDF but generate a low temperature. For example, at stoichiometric mixture with nozzle 1.25 USgal/h, NOx and CO generated by PME decreased of 27% and 30% respectively compared to CDF. PME has recorded about 12% drop in an average temperature compared to the CDF at the same condition. The higher fuel flow rate used, results more heat and emission generated. The results indicated may be benefits to using biodiesel in industrial processes due to less pollution production
